In this paper is analyzed a case study of an industry project concerning irrigation decision support system (DSS) suitable for precision agriculture applications. In particular, a first prototype irrigation module has been developed by testing different components. The prototypal system concerns the irrigation management by reading field and weather values and, by enabling electrovalves through cloud control. A web panel will monitor in real time all sensors data, besides the DSS will activate or disactivate the irrigation pipelines. The irrigation decision is performed by comparing the measurements with pre-set threshold limits of sensor values and by analyzing predicted weather data. The paper describes in details the network design and implementation by discussing the sequence diagram describing the DSS data flow. Finally is proposed the DSS algorithm by discussing the DSS logic and its first implementation. The proposed DSS behaves as an engine processing simultaneously multiple parameters. The goal of the paper is to prove how potentially a microcontroller can perform a DSS which can be customized for different cultivations.

Full textAbstract:
Irrigation plays a pivotal role in Southern Europe, and its importance is expected to further increase due to rising climatic variability. Concurrently, the European Water Framework Directive (WFD) mandates the safeguarding of water bodies and the implementation of incentive pricing strategies to promote efficient water management. Within this context, Irrigation Scheduling Decision Support Systems (IS-DSS) could contribute to the achievement of these objectives, although there are still obstacles to their adoption due to uncertainties regarding their potential benefits. This paper aims to derive a pricing model that reflects actual water use through the adoption of an IS-DSS. The innovation of this study lies in showing that adopting an IS-DSS to reduce irrigation volumes can potentially lower concession fees in collective irrigation systems. Thus, it contributes to the fulfilment of the WFD’s objectives regarding incentive water pricing. Notably, the tool is evaluated using the case study of a farm located in the Mediterranean region. The results demonstrate the dual benefits of IS-DSS adoption: on the one hand, it helps preserve water resources with a 24% reduction in irrigation volumes; on the other, it decreases irrigation costs by 20% at the farm level and by 9.4% at the irrigation district level. Therefore, the presented study provides insights into the potential of IS-DSS to enhance water pricing policies to promote efficient water management in Southern European agriculture in alignment with the WFD requirements.

Full textAbstract:
The efficient management of irrigation water can affect crop profitability quite significantly. The application of precision irrigation based on soil monitoring can help manage water resources. In viticulture, the irrigation technique is thought to strongly influence grape ripening and the final grape composition. In this study, an irrigation decision support system was compared to a surface drip irrigation system in a commercial vineyard located in Andrea (Southern Italy) planted with Vitis vinifera cv. Montepulciano. We aimed to investigate the ability of the DSS to save water while maintaining an acceptable yield and quality of the grapes. To allow for the comparison, eco-physiological as well as yield parameters were measured during the irrigation periods in both irrigation systems over two years (2019 and 2020). The results indicate that the vines grown using the DSS treatment were less stressed compared to the plants grown using farm irrigation in both years. The yield attributes showed slight or no significant differences between the treatments. The quality results showed no significant differences between the treatments in both years. Our results indicate that with savings of 10% and 17% of the irrigation water in the first and second year, respectively, the DSS was able to maintain good yield and quality levels as compared to the farm irrigation system. These two-year results provide a promising implementation of its use in precision irrigation.

HighlightsMulti-faceted research efforts converged to an automated irrigation decision support system (DSS).Low-cost, solar-powered, wireless plant abiotic and biotic stress sensors were developed to aid the DSS.Low-cost, accurate TDR soil water sensors and a wireless node and gateway system were developed for the DSS.Sensor systems and research-based algorithms were integrated into an automated irrigation DSS and control system.Abstract. Variable-rate irrigation (VRI) is now possible with every new center pivot irrigation system sold, either using sector (speed) control or both sector and zone (radial along the pipeline) control. However, decision support systems able to generate a prescription for spatially varying irrigation based on crop water need have lagged far behind VRI equipment. Irrigation based on crop water need has been shown to increase both crop water productivity and nutrient use efficiency, meaning that an effective VRI decision support system (DSS) could improve profitability while conserving resources. In this article, we report separately on a VRI DSS using sensor-based plant and soil water feedback as implemented in four U.S. states. This article describes the genesis and development of the Irrigation Scheduling Supervisory Control and Data Acquisition (ISSCADA) system, of the integral plant and soil sensors, and of its wireless sensor network subsystems, as well as the role of multi-location research efforts and cooperative research and development agreements in the development of the needed plant and soil sensors and the ISSCADA and wireless sensor network systems.

Full textAbstract:
The sustainable management of water resources is one of the most important topics to face future climate change and food security. Many countries facing a serious water crisis, due to both natural and artificial causes. The efficient use of water in agriculture is one of the most significant agricultural challenges that modern technologies. These last are considered powerful management instruments able to help farmers achieve the best efficiency in irrigation water use and to increase their incomes by obtaining the highest possible crop yield. In this context, within the project “An advanced low cost system for farm irrigation support—LCIS” (a joint Italian Israeli R&D project), a fully transferable Decision Support Systems (DSS) for irrigation support, based on three different methodologies representative of the state of the art in irrigation management tools (W-Tens, in situ soil sensor; IRRISAT®, remote sensing; W-Mod, simulation modelling of water balance in the soil-plant and atmosphere system), has been developed. These three LCIS-DSS tools have been evaluated, in terms of their ability to support the farmer in irrigation management, in a real applicative case study in Italy and Israel. The main challenge of a new DSS for irrigation is attributed to the uncertain factors during the growing season such as weather uncertainty, and crop monitoring platform. For encounter this challenge, we developed during two years the LCIS, a web-based real-time DSS for irrigation scheduling using low-cost imaging spectroscopy for state estimation of the agriculture system and probabilistic short- and medium-term climate forecasts. While the majority of the existing DSS models are incorporated directly into the optimization framework, we propose to integrate continuous feedback from the field (e.g., soil moisture, crop water-stress, plant stage, LAI, and biomass) estimated based on remote sensing information. These field data will be collected by the point-based spectrometer and hyperspectral imaging system. Then a low-cost camera will be designed for specific spectral/spatial parameters (bound to the required feedbacks). The main objectives were: developing real-time Decision Support System (DSS) for optimal irrigation scheduling at farm scale for crop yield improvement, reducing irrigation cost, and water saving; developing a low-cost imaging spectroscopy framework to support the irrigation scheduling DSS above and facilitates its use in countries/places where expensive imaging spectroscopy is not available; examining the developed framework in real-life application, the framework will be calibrated evaluated using high resolution devices and tested using a low-cost system in Israel and Italy farms.

Full textAbstract:
The IrrigaSys decision support system (DSS) has supported farmers’ decision-making regarding irrigation scheduling in the Sorraia Valley irrigation district in Southern Portugal over a span of six years (2017–2022). This study aims to conduct a postevaluation of farmers’ adherence to the DSS, employing a multicriteria analysis (MCA) approach with data from the 2019 (driest year) and 2020 (average year) growing seasons. Two distinct scenarios were taken into consideration: the first focused on water conservation, and the second centered on farmers’ economic returns. The outcomes of the first scenario revealed that farmers exhibited a reasonable level of expertise, particularly during the driest season. They achieved water-saving indicators comparable to those obtained when adhering to optimized irrigation schedules generated weekly by the DSS. In the wetter season, discrepancies emerged between farmers’ and model indicators, primarily attributed to challenges in integrating reliable information from precipitation forecasts into the decision-making process. In the second scenario, both farmers’ and model results exhibited close economic indicators throughout both seasons. While IrrigaSys requires further developments, these results show that the DSS has effectively contributed to supporting irrigation water management in the study region.

Full textAbstract:
Improvements in irrigation water productivity constitute an ongoing effort globally. In California, growers are under regulatory pressure to stabilize groundwater levels and reduce nitrate leaching, partially, by further improvements in irrigation optimization. Evapotranspiration (ET)-based methods can inform crop water requirements and boost irrigation efficiency, but in practice, they can be challenging for farmers to implement, especially in vegetable systems. Irrigation field trials were conducted near Salinas CA in 2018 and 2019 to evaluate the crop coefficient model employed by the CropManage ET-based irrigation decision support system (DSS) for summer cauliflower (Brassica oleracea var. botrytis cv. Symphony) and investigate potential water savings through improved irrigation scheduling. Overhead sprinklers were used for crop establishment, and surface drip was used subsequently. A randomized complete block design was used to administer treatments near 50, 75, 100, and 150% of crop evapotranspiration (ET) during the drip period with an added treatment at 125% in 2019. Water requirement for the 100% treatment was determined by the CropManage DSS model based on crop coefficients derived from fractional canopy cover. Deliveries to remaining treatments were scaled proportionally. The total yield and irrigation productivity were maximized by the 100% treatment both years with total applied water ranging from 275 to 300 mm. At present, the reported water application for summer cauliflower averages 465 mm in the region. Hence, implementing ET-based irrigation scheduling, administered through the CropManage DSS, could reduce water use in summer cauliflower by an average of 30% relative to current practices and serve to enhance groundwater management while maintaining crop returns.

Full textAbstract:
Purpose: Different irrigation systems exist and they all possess various degrees of benefits in enhancing food sufficiency. In this study however, the enhancement of capillary irrigation system through an integrated fuzzy logic controller with Decision Support System (DSS) to ensure improvement in water saving for irrigation thereby improving crop yield towards food security was examined and achieved.
 Methodology: An integrated fuzzy logic controller with Decision Support System (DSS) for capillary irrigation system was adopted for the enhancement of water saving for irrigation. By using this method, the challenges of irrigation management which is prevalent with capillary irrigation system is minimised using the fuzzy logic controller. An Internet of things (IoT) based weather station for computation of potential evapotranspiration (PET), for measuring rainfall and a VH400 moisture content sensor for monitoring the volumetric water content of soil, were some facilities used to control the water level depth (WLD) autonomously through a fuzzy controller simulated in MATLAB and implemented on Arduino Mega.
 Findings: The soil moisture content (SMC) depicts that fuzzy controlled water level depth (WLD) is able to compensate reduction of water in crop medium that took place due to plant water uptake which changes daily. The result proves that dynamics of water supply depth has substantial effects on the water absorption flow rate, wetting pattern, soil water content and cumulative infiltration which are proportional to the water supply depth decrement. 
 Unique Contribution to Practice: An integrated fuzzy logic controller with Decision Support System (DSS) is a new technique proposed for managing capillary irrigation system as it offers enhanced water saving capacity (irrigation volume) based on crop demand.

La tecnologia agricola è sviluppata a una velocità elevata verso una nuova era. Ha superato
l'evoluzione dell'Agricoltura 2.0, 3.0 e sta subendo l'Agricoltura 4.0 con tecnologie avanzate per
l'ottimizzazione delle colture, del suolo e dell'ambiente. L'agricoltura 4.0 connessa con l'ausilio
dell'internet delle cose (IoT) può gestire non solo la fertirrigazione ma anche altre tecniche
agronomiche. Il sistema di fertirrigazione solare è un sistema di fertirrigazione intelligente che integra
software e hardware a supporto delle decisioni dell'agricoltore e in grado di tradurre le decisioni in
azioni (es. fertilizzazione e gestione dell'irrigazione) in modalità automatizzata. Il sistema di
fertirrigazione solare sposta la fertirrigazione manuale in un'era di automazione e intelligenza
artificiale. Raccoglie i dati ambientali dal campo, li integra con le previsioni meteorologiche prelevate
dalla rete e implementa la corretta soluzione di fertirrigazione per il tipo di coltura selezionata e la
specifica fase di crescita. Queste decisioni intelligenti del sistema di fertirrigazione solare sono
supportate dal sistema di supporto alle decisioni (DSS) che fornisce decisioni autonome in tutte le
condizioni ambientali. Il DSS ha sviluppato i processi agricoli dalle funzioni manuali a quelle
automatiche massimizzando produttività e precisione. Tuttavia, il sistema ha registrato alcuni
problemi in situazioni difficili, sulla base dei quali lo studio intende sviluppare il sistema affrontando
tali problemi. Lo studio ha tre obiettivi: 1) sviluppo del database del sistema di fertirrigazione solare;
2) gestione dell'acqua delle colture tramite piattaforma desktop basata sul web; e 3) valutazione
dell'evapotraspirazione di riferimento per tutte le colture.
Lo sviluppo del sistema di fertirrigazione solare è stato eseguito utilizzando i più recenti sistemi e
applicazioni moderne con alcune nuove funzioni come il confronto dei dati raccolti in tempo reale
dei due anni con i dati del sistema. Il sistema di fertirrigazione solare risente negativamente dei rischi
naturali, animali e, in generale, di usi errati. Dopo lo sviluppo del sistema, le differenze
nell'acquisizione dei dati sono state la preoccupazione principale. In un sistema agricolo, diversi
processi eseguono lo stesso lavoro per ottenere risultati, mentre diverse apparecchiature misurano e
generano diversi tipi di set di dati. I dati vengono analizzati utilizzando un'unica piattaforma per
renderli paralleli come un unico indicatore. Lo studio suggerisce vari contributi che includono:
1. Sviluppo del sistema di fertirrigazione solare utilizzando il DSS che si basa su funzioni di
microservizi e consente agli agronomi di fornire con successo set di dati orientati ai risultati
analizzando la coltura e set di dati ambientali.
2. E' stata generata l'analisi del database RDBMS (Politecnico di Bari (PoliBa)) seguita
dall'applicazione online denominata Solar Fertigation. L'applicazione online trasferisce una
terminologia particolare alle differenze nei dati dove un particolare processo attiva la
fertirrigazione per le colture in campo.
3. Sono state acquisite previsioni meteorologiche e dati meteorologici per stimare il miglior
modello possibile per una crescita e una produzione ottimali delle colture. Gli effetti di
temperatura, umidità, radiazioni UV, pressione atmosferica, velocità del vento e
precipitazioni sono stati confrontati con le fasi di crescita delle colture nei periodi 2019-2021
in quattro diverse regioni italiane con una piovosità media annua di 806 mm (Campobasso) e 675 mm (Regione Puglia). Gli eventi di precipitazioni elevate hanno influenzato la produzione
delle colture, mentre gli eventi piovosi medi tendono ad avere un'elevata domanda di
fabbisogno di acqua per l'irrigazione.
Gli studi hanno rilevato che l'attuale spessore della vegetazione si trova all'interno dell'intervallo
ideale, sebbene si sarebbe potuta formare una tendenza migliore per la produzione di grano. Il sistema
ha sviluppato una particolare strategia a lungo termine e tecniche di gestione delle colture per
vantaggi economici a breve e lungo termine in particolari condizioni ambientali per rese e produzione
più elevate.<br>Agriculture technology is developed at a fast speed towards a new era. It has passed the evolution of
Agriculture 2.0, 3.0 and is undergoing the agriculture 4.0 with advanced technologies for crop, soil
and environmental optimization. Agriculture 4.0 connected with the help of the internet of things
(IoT) can manage not only fertigation but also other agronomic techniques. The solar fertigation
system is a smart fertigation system that integrates both, software and hardware to support the
decisions of the farmer and capable of translating decisions into actions (e.g., fertilization and
irrigation management) in an automated mode. The solar fertigation system shifts the manual
fertigation into an era of automation and artificial intelligence. It collects the environmental data from
the field, integrates them with the weather forecasts taken from the network and implements the
correct fertigation solution for the type of the selected crop and the specific growth stage. These
intelligent decisions of the solar fertigation system are supported by the decision support system
(DSS) which provides autonomous decisions in all environment conditions. The DSS developed the
agricultural processes from manual to automatic functions by maximizing productivity and precision.
Though, the system recorded a few issues in challenging situations, on the basis of which, the study
is meant to develop the system by addressing those issues. This study presents three objectives: 1)
development of solar fertigation system database; 2) crop water management using web based
desktop platform; and 3) reference evapotranspiration assessment for all crops.
The development of the solar fertigation system was performed by using the latest systems and
modern applications with some new functions such as a comparison of the two years real-time
collected data with the system's data. The solar fertigation system is negatively affected by natural
hazards, animals, and overall, by wrong uses. After the system's development, differences in the data
acquisition were the main concern. In an agricultural system, different processes perform the same
work for getting results, while different equipment measure and generate different types of datasets.
Data are analyzed by using a single platform to make it parallel as a single gauge. The study suggests
various contributions that include:
1. Development of the solar fertigation system using the DSS which is based on microservice
functions and allows agronomists to successfully deliver result-oriented datasets by analyzing
the crop, and environmental datasets.
2. Analysis of the RDBMS database (Politecnico di Bari (PoliBa)) followed by the online
application known as Solar Fertigation was generated. The online application transfers
particular terminology to the differences in the data where a particular process activates the
fertigation for crops in the field.
3. Weather forecast and meteorological data were acquired to estimate the best possible model
for optimum crop growth and production. The temperature, humidity, UV radiation, air
pressure, wind speed, and rainfall effects were compared with the crop growth stages from
the periods 2019-2021 at four different regions in Italy with a mean annual rainfall of 806 mm
(Campobasso), and 675 mm (Apulia region). High rainfall events affected crop production
while average rainfall events tend to have a high demand for irrigation water requirement.
The studies found that present vegetation thickness is found within the ideal range though a morebetter
trend for grain production could have been formed. The system developed a particular longterm
strategy, and crop management techniques for short- and long-time economic benefits in
particular environmental conditions for higher yields and production.

In general and as a result of the triple interaction among the studied treatments, using drip irrigation either with soil mulching or not, 80 % of ETc as a water regime was the best.

But reducing the compost rate to 24 ton ha-1 attained the highest net profit for local potato consumption and achieved the best significant net profit for exportation.

The third chapter considers the impact of a temporary irrigation restriction on farmer’s water demand function: imposing a water limitation at a given period will not necessarily induce a reduction of the yearly water consumption.

Full textAbstract:
Devant l'inadequation aux besoins des agriculteurs des moyens d'aide au pilotage des irrigations existants, un systeme expert a ete developpe. Ce systeme permet d'elaborer des strategies d'irrigation qui prennent en compte le contexte technico-economique de l'exploitation et permettent une verification de l'adaptation objectif-moyens en diminuant les besoins de point. Ce systeme est concu pour fonctionner sur micro-ordinateur ou sur serveur videotex (minitel). La methode d'elaboration de ce systeme a consiste a interviewer un expert, a formaliser la connaissance recueillie et a la coder dans un langage dit d'intelligence artificielle. Les connaissances mises en uvre dans le domaine des strategies et du pilotage des irrigations sont de plusieurs types. Les formalismes de representation les plus adaptes peuvent donc, etre differents: formalisme oriente objet pour les objets manipules; programmation logique pour les etapes de diagnostic; algorithmique pour l'elaboration des strategies et la modelisation du bilan hydrique. Ces differents types de connaissances justifient l'utilisation d'un outil permettant la mise en uvre des differents modes de representation qui leur sont le plus adapte. C'est le cas du langage que nous avons choisi (spiral). Le prototype ainsi obtenu a fait l'objet d'essais sur des parcelles de pommiers irrigues par mini-diffuseurs. Le pilotage effectue permet une economie d'eau par rapport a la pratique de l'agriculteur sans pour autant stresser la culture. Ce resultat est encourageant, mais il faut le considerer avec prudence: en effet, il depend du choix des parametres d'entree. Ce qui nous conduit a proposer un calage periodique du modele par des mesures in situ

Full textAbstract:
Abstract The fast transition of India from a water-stressed to a water-scarce country has provided additional impetus for the search for interventions and decision support systems (DSSs) for solutions to problems arising from a mismatch between demand and supply and competing demands of economic and environmental sectors. Agriculture is the largest user of freshwater and increasing water productivity in agriculture is a national challenge requiring urgent attention. Globally, DSSs have gained immense popularity in various domains and, more recently, in agriculture and water resources management but are still limited in developing countries like India. This chapter presents a comprehensive compilation and stocktake of the DSSs developed at various scales in India and specific to the Ganges Basin, aimed at serving as a foundation for future work in this direction. After the criteria-based screening of the literature and reports, each selected DSS was analysed in the context of the aspects covered, key criteria, and the parameters such as relevance, applicability, focus, and scale of application. To reinforce the recommendations, KIIs were held with selected experts and stakeholders. A matrix approach was employed to compile and review the DSS with broader segregation under (i) crop and farm-based decision support systems, (ii) DSS based on artificial intelligence, enhanced machine learning, fuzzy multi-criteria decision making, and knowledge systems, (iii) DSS for real-time operation of micro-irrigation systems, (iv) DSS for management of tanks and reservoirs for water-deficit regions, and (v) DSS for improving water productivity under canal commands and conjunctive management of surface and groundwater resources. The selected DSSs were then analysed for focus, key findings, relevance, applicability, and scale of application of the DSS.

Full textAbstract:
Work to reclaim and restore land that had once been productive but which was believed to have fallen into dis/mis-use was a key foundation of the imperial environmental enterprise, and an inherently political act. Chapter 2 looks at state efforts to reclaim land via planting and irrigation, examining anxieties over desertification and wind-drift sands, and the political symbolism of projects such as the Murgab Imperial Estate, an experiment in irrigation at the Murgab river delta in Transcaspia. Yet comparing and contrasting the actions of imperial outsiders and Central Asian villagers and tenant farmers reveals a vast gulf between the imagined worlds of restitution and the physical realities of land degradation. Corruption, salinization, erosion, and water disputes all came to characterize schemes that had been intended to project imperial power and to act as beacons for the acceptance of Russian subjecthood. As such, the chapter points towards the gradual discovery of the instabilities and intricacies of local ecosystems and, ultimately, the limits of state land reclamation efforts. In this reading, sand, silt, and mud were powerful material agents that both enhanced and undercut imperial projections of power.

Full textAbstract:
Groundwater is an important source of supply, is available in almost all regions of the Earth, constituting an important natural resource. In addition, having knowledge of this resource in terms of quality and quantity is of paramount importance, as these waters are often used for human supply, for irrigation in rural areas and for industrial purposes. In this context, the North Fluminense region, especially the municipality of Campos dos Goytacazes, has been demanding more and more for the use of water resources, due to the population and business increase, motivated, above all, by the huge undertaking that is the Açu port complex, installed in the neighboring municipality, São João da Barra. This reality points to the relevance of developing work that will contribute to a better knowledge of groundwater. This research aims to contribute to a better knowledge of the water quality of the shallow free aquifers in the municipality of Campos dos Goytacazes. As for the methodology, the following steps will be carried out: collection of bibliographic and documentary data, such as conference proceedings, books, ordinance, laws, articles, theses, dissertations, and others; literature review; selection of physicochemical data from existing shallow wells; comparison of physical-chemical parameters with the maximum values allowed with Consolidation Ordinance Nº. 5 established by the Ministry of Health; map creation; and elaboration of table and graphs. It is expected with this research to produce and make available information that can contribute to the sustainable management of underground water resources in the municipality of Campos dos Goytacazes

Full textAbstract:
The recognition of Serra de Tramontana as a World Heritage Site was a desire of the local community on the island of Mallorca in Spain. Historically, the Serra was characterized by the interactions between the different cultures that sailed in the Mediterranean Sea, especially the Arabs, who introduced hydraulic systems, guaranteeing the implantation of the settlements through the infrastructure of paths, buildings, irrigation channels with stone walls. Ensuring the protection of such a complex and unique landscape demanded the elaboration of a Master Plan, aimed at the analysis, design and management of the landscape, with actions and strategies linking development and heritage resources. This research presents the main concepts, methodologies, processes of elaboration and management of that Master Plan, which proved to be a judicious document on human adaptation in the territory, presenting heritage assets together with guidelines for sustainable development, focused on the protection of local culture and continuity of the traditional way of life, as well as the survival of native species, and preservation of biodiversity as a whole. Keywords: Cultural landscape, territorial planning, heritage, economic development O reconhecimento da Serra Tramontana como um patrimônio da humanidade era um desejo da comunidade local na ilha de Mallorca na Espanha. Historicamente, a Serra se caracterizou pelas interações entre as diversas culturas que navegaram no mar Mediterrâneo, em especial os árabes, que introduziram no local os sistemas hidráulicos islâmicos, garantindo a implantação dos assentamentos através de infraestruturas de caminhos, edificações e canais em pedra. Garantir a proteção de uma paisagem tão complexa e única, demandou a elaboração de um Plano Territorial, voltado ao reconhecimento, tratamento e gestão da paisagem, com ações e estratégias vinculando desenvolvimento e recursos patrimoniais. Essa pesquisa apresenta os principais conceitos, metodologias, processos de elaboração e gestão do Plano, que se mostrou como um documento criterioso sobre a adaptação humana no território, apresentando os bens patrimoniais em conjunto com diretrizes para o desenvolvimento sustentável, focado na proteção da cultura local e continuidade do modo de vida tradicional, bem como na sobrevivência das espécies nativas, e preservação da biodiversidade como um todo e possibilitou o reconhecimento da Serra Tramontana como Patrimônio da Humanidade pela Unesco.

Full textAbstract:
In recent years, climate change trends specific to the world’s regions have been observed in Lithuania. Droughts and torrential rains are increasingly being recorded, causing long-term waterlogging. As Lithuania is an agrarian country, the horticulture sector is developed. Abundant growers of potatoes, cabbage and other vegetables are counted in years. It is estimated that the consumption of potatoes in Lithuania is more than 96 kg per capita per year. However, potatoes, which are grown by the majority of crop farms, suffer most from frequent natural droughts. To lower droughts influence, farmers can install irrigation systems or use biological additives in the field, such as agroperlite and agrovermiculite. The experiment was conducted at the two experimental farms in Lithuania, growing ‘Vineta’ potatoes. The aim of the study was to determine the dynamics of soil moisture in May-August, when different amounts (effects of different percentages) of biological additives are added to the soil. In 2020, the amount of precipitation varied during the research period. During the whole period in Pupasodis fields precipitation was 234 mm. During observed period, 77% of all decades were drier than perennials (DNs). In Šilavotas fields, it was found that 351.5 mm of precipitation fell during the observed period, which is 164.3 mm more than in the Pupasodis area. The distance between experiment plots was more than 70 km. The study results show that soil temperature correlates with exponential dependence with precipitation. The correlation coefficient r = 0.69, and when assessing the relationship between soil temperature and ambient temperature, a linear dependence and R = 0.5649 were found.

Full textAbstract:
Secondary metabolites in plants are organic molecules that fulfil non-essential but necessary functions. Among these, phenolic compounds or phenylpropanoids play a fundamental role. They are biochemically modulated and synthesised via two principal pathways, the shikimic acid pathway and, to a lesser extent, the malonic acid pathway. The enzyme Phenylalanine Ammonium Lyase (PAL) is found in the shikimic acid pathway and is responsible for naturally synthesising polyphenols, phytoalexins and phytotoxins in plants. The results obtained by the Spanish National Research Council (CSIC) show how applying Brotomax® to a healthy grapevine plantation can increase the enzymatic activity of PAL in the leaves, with statistically significant differences compared to untreated or control plants. Better results are also obtained when the elicitor is applied via irrigation as opposed to foliar application. Brotomax® does not directly provide the plant with phenolic compounds, instead it influences the biochemical modulation of these compounds and lets nature regulate and balance their action..................................................................................Los metabolitos secundarios de las plantas son moléculas orgánicas que cumplen funciones no esenciales, pero sí necesarias. Dentro de ellos ocupan un papel fundamental los componentes fenólicos o fenilpropanoides, los cuales son modulables bioquímicamente y sintetizados principalmente en dos rutas, la ruta del ácido shikímico y en menor medida en la ruta del ácido malónico. La enzima Fenilalanina Amonio Liasa (PAL) se encuentra en la ruta del ácido shikímico y es la responsable de la síntesis de los polifenoles, fitoalexinas y fitotoxinas en las plantas de manera natural. Los resultados obtenidos en el Consejo Superior de Investigaciones Científicas (CSIC) demuestran cómo la aplicación de Brotomax® en una plantación sana de uva de mesa, es capaz de incrementar la actividad enzimática de la PAL en hojas, existiendo diferencias estadísticas respecto al no tratado o testigo. También se obtienen mejores resultados cuando realizamos la aplicación vía riego de dicho elicitor en comparación a su aplicación vía foliar. Brotomax® no aporta directamente los compuestos fenólicos a la planta, sino que incide en la modulación bioquímica de los mismos; y deja que la naturaleza regule y equilibre su acción.

Full textAbstract:
La réutilisation planifiée des eaux usées épurées peut soulager les ressources en eau conventionnelles et réduire la consommation d'eau. Elle constitue une option d'action possible dans la gestion intégrée des ressources en eau, si les avantages dans le contexte local l'emportent sur les dépenses nécessaires (traitement supplémentaire, infrastructure, coûts, énergie). Le présent projet a cherché à savoir si la réutilisation de l'eau pouvait être une option pertinente pour la gestion des ressources en eau en Suisse. Pour ce faire, les données existantes sur la disponibilité et la consommation d'eau ont été analysées et une enquête sur le sujet a été menée auprès des services cantonaux de l'environnement. En raison du changement climatique, les périodes de fortes chaleurs sont de plus en plus fréquentes en Suisse, notamment en été. Les épisodes de sécheresse qui en découlent entraînent une augmentation des besoins en eau pour différentes applications (irrigation pour l'agriculture et dans les villes, eau de refroidissement, etc.). Au niveau local, les représentants de 19 des 26 cantons ont identifié un besoin de réutilisation de l'eau pour diverses applications, en particulier pour l'irrigation. De plus, on s'attend à une augmentation de ces besoins avec le changement climatique en cours. En outre, la réutilisation de l'eau présente des synergies avec d'autres mesures de gestion des ressources en eau, par exemple le stockage de l'eau pour les périodes où les besoins sont plus importants. Bien entendu, la réutilisation de l'eau doit être soumise à des exigences claires en termes de qualité et de quantité utilisable et des directives techniques doivent être établies, afin de ne pas mettre en danger l'homme et l'environnement. De plus, pour que les projets de réutilisation de l'eau puissent être mis en oeuvre avec succès à long terme, l'acceptation sociale doit être garantie. Actuellement, la réutilisation de l'eau n'est pas explicitement réglementée dans le droit suisse ; seule l'irrigation est implicitement interdite, alors que toutes les autres applications sont autorisées, mais sans directives concernant la mise en oeuvre ou la qualité. En outre, la Suisse manque d'expérience, de connaissances et de compétences pour la mise en place de la réutilisation de l’eau. Il est donc recommandé d’acquérir de l’expérience par le biais de projets pilotes et d’évaluer les informations spécifiques au projet (coûts, infrastructure nécessaire, etc.). En parallèle, un processus coordonné d'adaptation de la législation est nécessaire pour encadrer une mise en oeuvre sûre de la pratique en Suisse. Cela permettra de garantir que la réutilisation de l'eau soit une mesure fiable et contrôlée pour la gestion future des ressources en eau.

Miyamoto, Seiichi, and Rami Keren. Improving Efficiency of Reclamation of Sodium-Affected Soils. United States Department of Agriculture, 2000. http://dx.doi.org/10.32747/2000.7570569.bard.
Full textAbstract:
Sodium affected soils, along with salt-affected soils, are distributed widely in irrigated areas of the arid and semi-arid region of the world. Some of these soils can and must be reclaimed to meet the increasing demand for food, and existing irrigated lands must be managed to reduce salinization and alkalization associated with deteriorating irrigation water quality. This project was conducted for examining ways to reduce the use of chemical amendments and large quantities of leaching water for reclaiming sodic soils or for preventing soil sodification, We hypothesized that sodicity of calcareous soils irrigated with moderately sodic irrigation water can be controlled by maximizing dissolution of soil CaCO3. The work performed in Israel has shown that dissolution of CaCO3 can be enhanced by elevating the CO2 partial pressure in soils, and by increasing pore water velocity. The concentration of Ca in pore water was at an order of 1.5 mmolc L-1 at a CO2 partial pressure of 5 kPa, which is sufficient to maintain SAR below 4 at salinity of irrigation water of 0.5 dS m-1 or less. Incorporation of crop residue at a flesh weight of 100 Mg ha-1 reduced the exchangeable Na percentage from 19 to 5%, while it remained 14% without crop residue application These findings indicate a possibility of preventing soil sodification with appropriate crop rotation and residue management without chemical amendments, provided that soils remain permeable. In the case of highly sodic soils, dissolution of CaCO3 alone is usually insufficient to maintain soil permeability during initial leaching. We examined the effect of salinity and sodicity on water infiltration, then developed a way to estimate the amendments required on the basis of water infiltration and drainage characteristics, rather than the traditional idea of reducing the exchangeable Na percentage to a pre-fixed value. Initial indications from soil column and lysimeter study are that the proposed method provides realistic estimates of amendment requirements. We further hypothesized that cultivation of salt-tolerant plants with water of elevated salinity can enhance reclamation of severely Na-affected soils primarily through improved water infiltration and increased dissolution of CaCO3 through respiration. An outdoor lysimeter experiment using two saline sodic Entisols sodded with saltgrass for two seasons did not necessarily support this hypothesis. While there was an evidence of increased removal of the exchangeable Na originally present in the soils, the final salinity and sodicity measured were lowest without sod, and highest when sodded. High transpiration rates, coupled with low permeability and/or inadequate leaching seemed to have offset the potential benefits of increased CaCO3 dissolution and subsequent removal of exchangeable Na. Although vegetative means of reclaiming sodic soils had been reported to be effective in sandy soils with sufficient permeability, additional study is needed for its use in saline sodic soils under the high evaporative demand. The use of cool season grass after initial salt leaching with CaCl2 should be explored. Results obtained from this project have several potential applications, which include the use of crop residues for maintaining sodium balance, the use of CaCl2 for initial leaching of poorly permeable clayey sodic soils, and appraisal of sodicity effects, and appropriate rates and types of amendments required for reclamation

Den 15-19 maj 2022 medverkade Agtech 2030, genom undertecknad, i en delegationsresa till Israel. Resan var kulmen på olika aktiviteter under 3 års tid. En milstolpe skedde 2019 då vi fick ett brev från Israels ambassadör Ilan Ben-Dov, som resultat av en artikel vi hade skrivit på DN Debatt. Sedan dess har analyser och dialoger genomförts med tema Israel/Agtech. Syftet med resan som nu äntligen blev av var att ge ett keynoteföredrag, delta i diskussioner med svenska och israeliska företag samt göra studiebesök i innovationsmiljöer. Min roll var inte minst att identifiera samarbetsmöjligheter inom lantbruksteknik. Det var ett digert program som inkluderade konferenser, innovationscentra, en inkubator, universitetsbesök, företagsbesök och mingelevenemang. Några nedslag: Vi besökte bioteknikföretaget MeaTech i Tel Aviv som odlar fram artificiellt kött i sitt lab. De 3Dprintar fett- och proteintrådar med material framodlat genom stamceller. Och sedan får köttbitarna växa till sig i fermentorer. De har fått stora mängder riskkapital och menar att framtiden är kött utan att vi behöver några djur, för djur är inte hållbart anser dom. Vi fick smaka köttet. Vi besökte också Kibbutz Hatzerim i Negev (fotot). Där föddes den moderna droppbevattningen som lade grunden till företaget Netafim. Ett centralt begrepp var ”fertigation”, alltså bevattning med näringsberikat vatten. Vi fick höra om att anpassa näringsberikat vatten till varje segment av fälten (VRDI), om metoder för att hindra frostskador (frost migration) och om sub surface drip irrigation (SDI). Vi besökte också företagsinkubatorn “The Kitchen FoodTech Hub” i Ashdod. Peres Center for Peace and Innovation i Jaffa, var storslaget. Det är ett upplevelsebaserat innovationscentrum för att visualisera israeliska innovationer. Faculty of Agriculture, Food & Environment, Hebrew University i Rehovot, gjorde också intryck. De har omfattande forskning och blan annat experimentväxthus fulla av sensorer av olika slag. Volcani Center – Agricultural Research Organization i Rishon Lezion, är ett slags institut med världsledande forskning inom både agtech och foodtech.Under veckan hann vi med två stora konferenser. Den ena skedde på Start-Up Nation Central med fokus på start-ups och globala företag. Den andra ägde rum på Israel Export Institute. Rubriken på mitt föredrag där var “Agtech innovation: Urgent needs and fantastic opportunities”. Jag diskuterade ett antal utmaningar och problem men underströk att lantbruket sprudlar av innovationskraft och visade på flera flera exempel. Jag berättade också om Agtech 2030. En allmän slutsats från resan var att Israel har stora visioner inom detta område.
