Abstract:
Organic vegetables produced in greenhouses and other controlled environments may fill a unique market niche as consumers demand local, high vegetables year round. However, limited technical information supports these production systems and more research is needed to provide recommendations for appropriate substrate mixes and nutrient management. Compost can be used as a substitute for peat-based media, and research results vary widely based on feedstock, compost method, and proportion used in mixes. Most studies consider compost in terms of peat-substitute or replacement and not as a source of fertility in soilless systems. Common challenges in using compost in soilless media are due to immaturity of the compost, poor water holding capacity, and unbalanced salinity and pH. It is possible to certify organic soilless production systems; however, the National Organic Program (NOP) of the U.S. Department of Agriculture has not yet provided clear rules and requirements supporting these systems. The objective of this article is to review the literature on soilless organic vegetable production, summarize results from the more widely studied topic of vegetable transplant production, and point to future research for organic agriculture.

Abstract:
Global food demand has increased in tandem with the world’s growing population, prompting calls for a new sustainable agricultural method. The scarcity of fertile soil and the world’s agricultural land have also become major concerns. Soilless and microgreen farming combined with nanotechnology may provide a revolutionary solution as well as a more sustainable and productive alternative to conventional farming. In this review, we look at the potential of nanotechnology in soilless and microgreen farming. The available but limited nanotechnology approaches in soilless farming include: (1) Nutrients nanoparticles to minimize nutrient losses and improve nutrient uptake and bioavailability in crops; (2) nano-sensing to provide real-time detection of p H, temperature, as well as quantifying the amount of the nutrient, allowing desired conditions control; and (3) incorporation of nanoparticles to improve the quality of substrate culture as crop cultivation growing medium. Meanwhile, potential nanotechnology applications in soilless and microgreen farming include: (1) Plant trait improvement against environmental disease and stress through nanomaterial application; (2) plant nanobionics to alter or improve the function of the plant tissue or organelle; and (3) extending the shelf life of microgreens by impregnating nanoparticles on the packaging or other preservation method.

Abstract:
Agricultural activities in Europe cover half of the total area of the continent and are simultaneously a cause of environmental impact and victims of the same impact. Horticultural or fruit crops are considered highly intensive and often employ many crop inputs such as fertilizers, pesticides, and various materials. Strawberry falls into this group, and it has grown in acreage and production more than others globally. The aim of this study is to compare the environmental impact of two strawberry cultivation systems in central Italy, a mulched soil tunnel and a soilless tunnel system. The method used to assess the impact is LCA, widely applied in agriculture and supported by international standards. The data used are mainly primary, related to 2018, and representative of the cultivation systems of central Italy. For impact assessment, the method selected was the CML_IA baseline version. From the results obtained, the two systems show a similar impact per kg of strawberries produced (e.g., for global warming: 0.785 kg CO2 eq for soilless, 0.778 kg CO2 eq for mulched soil tunnel). Reduced differences can be observed for the use of crop inputs (greater for the tunnel) and the use of materials and technology (greater for soilless). The mitigation measures considered concern the replacement of the packaging (excluding plastic) and the growing medium of the soilless using perlite and compost from insect breeding.

Abstract:
Fresh weight is a direct index of crop growth. It is difficult to continuously measure the fresh weight of bell peppers grown in soilless cultures, however, due to the difficulty in identifying the moisture condition of crops and growing media. The objective of this study was to develop a continuous and nondestructive measuring system for the fresh weight of bell peppers grown in soilless cultures considering the moisture content of growing media. The system simultaneously measures the trellis string’s supported weight and gravitational weight using tensile load cells. The moisture weight of growing media was calibrated during the growth period using changes in moisture content before and after the first irrigation of the day. The most stable time period for the measurement, from 03:00 to 06:00, was determined by analyzing the diurnal change in relative water content. To verify the accuracy of the system, the fruits, stems, leaves, and roots’ fresh weights were measured manually. The fresh weights measured by the developed system were in good agreement with those manually measured. The results confirm that our system can reliably and accurately measure fresh weights of bell peppers grown in soilless cultures. This method can be applied to continuous growth data collection for other crops grown in soilless cultures.

Abstract:
Two experiments were conducted in different cropping seasons under Mediterranean climatic conditions to investigate the impact of two cooling systems (fan-pad evaporative as opposed to fan ventilation) on greenhouse microclimate and soilless cucumber growth. The second objective of the experiment was to determine the most appropriate irrigation regime (between 0.24 and 0.32 L m−2) in relation to crop water uptake and greenhouse fertigation effluents. The use of a fan ventilation system enhanced the vapor pressure deficit; thus, the crop transpiration improved by 60% in relation to the transpiration rates of plants grown under the fan-pad system. Higher transpiration rates alleviated the heat load as the external–inside greenhouse air differences declined from 6.2 °C to 3 °C. The leaf–air temperature differential indicated that plants were not facing any water stress conditions for both cooling systems tested; however, fan ventilation reduced drainage emissions outflows (95% decrease) compared with evaporative cooling. Results also demonstrated that an irrigation regime of 0.24 L m−2 can be applied successfully in soilless cucumber crops, keeping the drainage to a minimum (20% of the nutrient solution supply). These results suggest that fan ventilation cooling system in conjugation with an appropriate irrigation regime prevents overheating and minimizes the nutrient and water losses in spring-grown soilless cucumber crops in Mediterranean greenhouses without compromising yield.

Abstract:
Greenhouse tomato (Lycopersicum esculentum Mill.) producers are urged to reduce their environmental footprint. Here, the suitability of biochar produced from tomato crop green waste as a substrate for soilless, hydroponic tomato production was evaluated. Substrates containing different combinations of biochar (BC) and pine (Pinus radiata D. Don) sawdust (SD) were produced (BC0-SD100, BC25-SD75, BC50-SD50, BC75-SD25, and BC100-SD0) and characterized. The effect of these substrates on tomato growth, yield, and fruit quality was studied. Most of the measured properties of substrates containing biochar were suited to use as a soilless substrate. The electrical conductivity (EC) of substrates containing biochar was initially high (>4.6 mS·cm−1), but was easily reduced to <0.5 mS·cm−1 by rinsing with water before use. The pH of substrates containing biochar was higher than is considered acceptable for tomato production (7.5–9.3) but did not significantly (P < 0.05) affect any plant growth, yield, and fruit quality indicators measured compared with those of plants grown in pine sawdust. The results support the concept of creating a closed loop system whereby biochar produced from tomato crop green waste is used as a substrate for soilless, hydroponic tomato production, providing a sustainable means to support the growth of high-value food crops.

Abstract:
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing the pros and cons of soilless culture and growing media constituents, the exploitation of different organic materials and their economic and environmental relevance.

Abstract:
A doença vassoura-de-bruxa reduziu expressivamente a produtividade dos cacauais da região sul da Bahia, maior produtora nacional. O controle genético da enfermidade, com o uso de plantas tolerantes e com alto potencial produtivo, tem sido a principal estratégia para o convívio com essa doença. O plantio de mudas clonais, provenientes de estacas enraizadas, tem mostrado ser uma prática promissora para a renovação da lavoura. O Instituto Biofábrica de Cacau (IBC), criado em 1999, tem como um de seus objetivos produzir e comercializar essas mudas. Estudos preliminares mostraram a necessidade de aprimoramento do protocolo, pois foram observados distúrbios nutricionais, apesar do uso elevado de fertilizantes. Os objetivos deste trabalho foram: avaliar a perda de nutrientes; comparar metodologias de extração de nutrientes em substratos; identificar a folha mais adequada para ser utilizada como diagnóstica; comparar formas de adubação; definir níveis críticos (NC) e doses recomendáveis de P e de N. Foram realizados dois experimentos, ambos em viveiro de produção de mudas do IBC, onde se utilizou o clone PH 16, com 12 mudas por parcela útil (uma muda por tubete de 288 cm3), sendo avaliados: diâmetro, altura, área foliar, matéria seca, concentração e conteúdo de nutrientes na planta. O primeiro experimento, implantado em julho de 2005, foi um fatorial 5x5+1: cinco substratos (misturas de fibra de coco – FC e Plantmax®), cinco doses de P no plantio (de zero a 0,8 g dm-3) e um tratamento adicional (P aplicado aos 30 dias); o segundo experimento, instalado em julho de 2006, foi um fatorial 2x5: duas formas de adubação, no substrato e foliar, e cinco doses de uréia, aplicadas semanalmente após o 82º dia. A análise do lixiviado do primeiro experimento identificou variações do pH, da condutividade elétrica e dos nutrientes de acordo com os tratamentos e com o tempo. A terceira folha do primeiro lançamento maduro foi a mais indicada para ser utilizada como folha diagnóstica. Para a maioria dos nutrientes, não foram encontradas correlações significativas entre os teores extraídos dos substratos, por metodologias distintas, com os absorvidos pelas plantas, exceto para P, K, Ca e Cu. A adubação com P em cobertura aumentou sua disponibilidade e absorção, mas não afetou o crescimento das mudas. Os melhores substratos foram os que continham entre 30 a 55% de FC. As doses recomendáveis, calculadas para obtenção de 99% da produção máxima da matéria seca da parte aérea, variaram de 136 a 275 g m-3 de P, aplicadas em préestaqueamento, de acordo com o substrato; e, para N, em aplicação semanal pósenraizamento, foi de 63 mg dm-3 para a adubação no substrato ou de 11,7 g L-1 para a adubação foliar. Para o N, a adubação no substrato foi superior à foliar. O NC de P no substrato variou de acordo com o extrator e o substrato e os NCs foliares foram de: 1,75 g kg-1 de P e 23,1 g kg-1 de N.
The witches' broom disease decreased expressively the cocoa productivity in Bahia south region, the biggest national producer. The disease genetic control, using tolerant plants with high potential productivity, has been the main strategy to cope with this disease. The cloned cutting breeding, originated from rooted cuttings, has proved to be a promising practice for crop renovation. The "Instituto Biofábrica de Cacau" (IBC) or Cocoa Biofactory Institute, founded in 1999, has one of its aims to produce and commercialize these rooted cuttings. Preliminary studies have shown the need of protocol improvement, as it was observed nutritional problems, despite the high use of fertilizers. The objectives of this work were: Evaluate nutrients losses; compare nutrient extraction methodologies in potting mix; identify the most suitable leaf to be used as diagnostic; compare different fertilization practice; define P and N critical levels (CL) and recommendable doses. It was carried out two experiments, both in cloning breeding nurseries of IBC, where it was used clone PH 16, with 12 cuttings by useful plot (one cutting by container of 288 cm3), being evaluated: diameter, height, foliar area, dry matter, concentration and nutrient content in plants. The first trial, implanted in July 2005, was a factorial 5x5+1: five potting mix (mix of coconut fiber – CF and Plantmax®) five doses of P in the planting (from 0 to 0.8 g dm-3) and an additional treatment (P applied on the 30th day); the second experiment, installed in July 2006, there was a factorial 2x5: two fertilization treatments, in potting mix and foliar, and five urea doses, applied weekly after the 82nd day. The first experiment leaching analysis identified variations of the pH, electric conductivity and nutrients according to treatments and time. The third leaf from first ripen sprout was the most indicated to be used as the diagnostic leaf. For most nutrients were not found significant correlation between substrate extract levels by distinct methodologies and the absorbed ones by plants, except for P, K, Ca and Cu. The P fertilization in covering increased its availability and absorption, but did not affect cutting growth. The best substrates were those contained between 30 and 55% of CF. The recommendable doses, assessed to obtain 99% of the maximum production of shoot dry matter, varied from 136 to 275 g m-3 of P, applied in the precutting, according to the substrate; and for N, in weekly pos-rooting application, was 63 mg dm-3 for the substrate fertilization or 11.7 g L-1 for foliar fertilization. For the N, the substrate fertilization was superior to foliar. The CL of P in the potting mix varied according to extractor and substrate and the foliar CLs were: 1.75 g kg-1 of P and 23.1 g kg-1 of N.

Abstract:
Freshwater is a finite resource that is rapidly becoming more scrutinized in agricultural consumption. Specialty crop producers, especially ornamental crop producers, must continually improve production sustainability, with regards to water resource management, in order to continue to stay economically viable. Soilless substrates were initially developed to have increased porosity and relatively low water holding capacity to ensure container crops would not remain overhydrated after irrigations or rain events. As a result, substrates were selected that are now considered to be in efficient in regards to water resource management. Therefore, to provide growers with additional means to improve production sustainability, soilless substrate hydrology needs be innovated to provide increased water availability while continuing to provide ample air filled porosity to ensure productive and efficient water interactions. Historically, soilless substrates have been characterized using "static" physical properties (i.e. maximum water holding capacity and minimum air-filled porosity). The research herein involves integrating dynamic soilless substrate hydraulic properties to understand how substrate hydrology can be manipulated to design sustainable substrates. This task involved adapting new technologies to analyze hydrological properties of peat and pine bark substrates by employing evaporative moisture characteristic measurements, which were originally designed for mineral soils, for soilless substrate analyses. Utilizing these evaporative measurements provide more accurate measures of substrate water potentials between -10 and -800 hPa than traditional pressure plate measurements. Soilless substrates were engineered, utilizing only three common substrate components [stabilized pine bark (Pinus taedea L.), Sphagnum peatmoss, and coconut coir fiber], via particle fractionation and fibrous additions. The engineering process yielded substrates with increased unsaturated hydraulic conductivity, pore connectivity, and more uniform pore size distributions. These substrates were tested in a greenhouse with irrigation systems designed to hold substrates at (-100 to -300 hPa) or approaching (-50 to -100 hPa) water potentials associated with drought stress. Substrate-water dynamics were monitored, as were plant morphology and drought stress indicators. It was determined that increased substrate unsaturated hydraulic conductivity within the production water potentials, allowed for increased crop growth, reduction in drought stress indicators, while producing marketable plants. Furthermore, individual plants were produced using as low as 5.3 L per plant. Increased production range substrate hydraulic conductivity was able to maintain necessary levels of air-filled porosity due to reduced irrigation volumes, while providing water for plants when needed. The substrates were able to conduct water from throughout the container volume to the plant roots for uptake when roots reduced substrate water potential. Furthermore, increased substrate hydraulic conductivity allowed plants within the substrate to continue absorbing water at much lower water potentials than those in unaltered (control) pine bark. Finally, HYDRUS models were utilized to simulate water flux through containerized substrates. These models allowed for better understanding of how individual hydraulic properties influence substrate water flux, and provided insight towards proportions of inaccessible pores, which do not maintain sufficient levels of available water. With the models, researchers will be able to simulate new substrates, and utilize model predictions to provide insight toward new substrates prior to implementing production tests. It has been determined, that increasing substrate hydraulic conductivity, which can be done with just commonly used components, water requirements for production can be reduced, to produce crops with minimal wasted water resources. Concluding, that re-engineering substrate hydrology can ameliorate production sustainability and decrease environmental impact.

Abstract:
Growing landscape trees in containers is a common practice in the nursery industry. In the southeastern United States, pine bark is often used as a container substrate, and two common amendments to pine bark are lime and micronutrients. In this study, three experiments were conducted to determine the effect of these amendments on the growth of a wide range of landscape tree species grown in pine bark. In the first experiment, nine species of landscape trees [Acer palmatum (Japanese maple), Acer saccharum (sugar maple), Cercis canadensis (redbud), Cornus florida (flowering dogwood), Cornus kousa (kousa dogwood), Koelreuteria paniculata (golden-rain tree), Magnolia x soulangiana (magnolia), Nyssa sylvatica (blackgum), and Quercus palustris (pin oak)] were grown from seed in two pine barks: pH 4.7 (low) and 5.1 (high). Preplant amendment treatments to each pine bark (Pinus taeda) were: with or without dolomitic limestone (3.57 kg.m-3) and with or without micronutrients (0.9 kg.m-3, Micromaxâ ¢). The same experiment was repeated using Koelreuteria paniculata and Quercus palustris, the same lime and micronutrient treatments, and two pine barks: pH 5.1 (low) and 5.8 (high). In both experiments, micronutrients increased shoot dry mass and height for all species, while lime decreased shoot dry mass and height for all species. Effect of bark type in the first experiment was variable, while shoot dry mass and height were highest in the low pH bark when the experiment was repeated. Substrate solution element concentrations increased when micronutrients were added, decreased when lime was added, and in general, concentrations were higher in low pH bark than in high pH bark. In the third experiment, Koelreuteria paniculata was grown from seed in pine bark amended with 0, 1.2, 2.4, or 3.6 kg.m-3 dolomitic limestone and 0 or 0.9 kg.m-3 micronutrients (Micromaxâ ¢). Initial pH for each lime rate was 4.0, 4.5, 5.0, and 5.5, respectively. Adding micronutrients increased shoot dry mass and height. Lime increased growth only at the 1.2 kg.m-3 rate. In general, substrate solution element concentrations increased when micronutrients were added and decreased when lime was added. In all three experiments, adding micronutrients was necessary regardless of pine bark pH, while adding lime was not necessary.

Abstract:
Soilless culture plant production presents a sector with unlimited potential for the horticulture industry. Soilless culture systems are environmentally friendly, resource-efficient, and support sustainable intensification in agriculture. Soilless culture system (SCS) crops in climate-controlled environments lead to higher crop production for the unit area and thus to a decrease in land usage in comparison to other cultivation methods. Here, we present the state-of-the-art of growing media and soilless culture and an outlook on further developments. For the future, it remains vital to identify and further develop sustainable materials, technologies and approaches, while keeping energy and production costs low and transportation distances short. The following chapters of this book provide further information and precise details, explaining step by step all these issues.

Abstract:
The majority of strawberries produced in the world are grown in the open field, and only in the past 50 years has protected cropping become established as a commercially viable system. Soilless culture (hydroponics) is an important component of this form of intensive production because it enables the strawberry crop to be grown above the ground (table top system) which can provides an improved root environment, nutrition and irrigation and at the same time easier fruit harvesting. Solid media systems predominate over liquid based systems with peat and coir being the most popular media. Future production appears to be increasingly towards year round production by the improved control of the plant environment, combined with reducing harvesting costs by robotic harvesting.

Abstract:
The biological properties of growing media (GM) in soilless cultivation have been considered minor traits for decades. However, there is a growing demand for alternative, cheaper GM constituents, characterized by organic origin. A better understanding of the biological processes of GM is a key factor in developing improved functional properties in the next generation of “living” GM. This chapter reviews current knowledge about the biological properties of GM for soilless cultivations, paying attention on their importance for plant nutrition, and the influence exerted by weeds, pests/pathogens and beneficial microorganisms to promote crop performance and improve the ability of GM to suppress pests and diseases. More understanding of the relationship between GM, microbial communities and plants increases opportunities to develop sustainable strategies for disease control, fertilization efficiency and horticulture performance.

Abstract:
It is estimated that the global population will reach approximately 10 billion people by 2050 and 66% of the world population will live in urban areas. This growth in cities creates demand for fresh products to maintain a healthy population, a product that often exposed to a long journey to reach the consumer, not only losing quality and nutritive value in the process, but also requiring a significant cost of fossil fuel for transportation and storage. However, the world’s agricultural land among being limited, is also facing major problems such as pollution, salinization and drought that do not favor crop production. The need for food security has paved the way for landless agriculture, becoming more popular in the urban area and becoming a part of urban farming. This article aims to examine hydroponic technologies to help expand the knowledge of their application in terms of science, origin, dynamics and farming systems. Among the benefits of soilless cultures; reservation of cultivated land for main crops; saving at least 90% of irrigation water; use of almost constant amount of recycled water; successfully growing almost every vegetable crops and having highest productivity compared to conventional agriculture. Therefore, it is an indispensable solution in areas where arable land is not available or in saline-prone areas, in short, wherever there is competition for land and water. The purpose of this study is an overview of soilless farming systems, explaining the most widely used hydroponic system, the importance of water quality, nutrient content, grown crops and ultimately cost benefit in terms of economics.
