Full textAbstract:
A survey was carried out to evaluate the effect of adequate and inadequate inorganic fertilizer rates on the yield of Paprika (Capsicum annuum var. angulosum mill) in Mutasa resettlement area, Mutasa district. Questionnaires and interviews were used to produce primary data from 42 respondents in 2009. Secondary data was obtained mainly from Agricultural Technical and Extension Services (AGRITEX) and Paprika Company of Zimbabwe. Mean yields of paprika obtained from adequate and inadequate basal and top dressing fertilisers were compared and analysed using ‘Z’ statistical test at 0.05 level of significance. Mean yield from inadequate fertilizer rates of 30 farmers was 0.8 t/ha. The mean yield from adequate fertilizer rates of 12 farmers was 1.0t/ha. Results showed that the two means were significantly different. Adequate fertiliser rates produced significantly higher mean yield than the mean yield from inadequate fertiliser rates. The higher mean yield was enhanced by the highest number of (5) top dressing split applications. The study therefore recommends the use of adequate rates of 700 – 1 000 kg/ha basal fertilizer, 250 – 350 kg/ha ammonium nitrate (AN) and 350 – 400 kg/ha of potassium chloride. The top dressing has to involve 5 split applications. This exploits its high fruit yielding potential. Additional research is required to determine response of the crop, as a high value crop, to foliar and fertigation fertiliser application.

Full textAbstract:
Wheat (<em>Triticum aestivum</em> L.) is vital for global food security due to its nutrition and widespread consumption. To support the growing population, using both organic and inorganic fertilizers enhances soil health and wheat yield. Mineral fertilizers directly affect crop yield and soil quality. Soil organic matter (SOM) is a crucial component for soil quality, microbial activity, decomposition, and nutrient cycling. The interaction between fertilizer uses and soil health is a complex phenomenon. The choice of fertilizer type, amount and application method impacts soil microbial populations and properties. Long-term balance fertilizer application enhances soil microbial biomass, with multiple factors like nitrogen source and application method as well. Sustainable agriculture and environmental health require both organic and mineral fertilizers use for better production. Public education on fertilizer synergy, crop yields and soil health are essential to enhance the productivity of agricultural products. Excessive inorganic fertilizer use leads to adverse consequences, including heavy metal accumulation, pollution, and environmental degradation. Organic fertilizers offer a more sustainable soil fertility approach, improving soil properties and crop yields. Application methods, like band spreading, trailing hose and burial, reduce nutrient loss and enhance soil structure. Combining organic and inorganic fertilizers is more effective for crop growth and yield, addressing limited arable land and global food demand. Fertilizers have been vital in ensuring food security for the expanding world population. With the population projected to exceed 9 billion by 2050, integrated soil nutrient management is crucial. Fertilizer use also impacts soil erosion, leading to topsoil loss and soil health decline. Nutrient-rich topsoil is vulnerable to erosion, especially in regions with inadequate fertilizer use. Proper nutrient management is a key to mitigating soil erosion and protecting soil and the environment. Research into the relationship between fertilizer use, crop production and soil erosion is needed for sustainable agricultural practices. © 2019 The Author(s)

Full textAbstract:
Low plant population and inadequate fertilizer application are constraints for maize production among farmers in Nepal. In order to identify the integrated effects of plant density and fertilizer dose for production of hybrid maize, series of on station experiments were carried out at Rampur, Chitwan, Nepal using strip plot design with three replications during winter seasons in two consecutive years 2016/17 and 2017/18. Two promising Nepalese hybrids namely RML-95/RML-96 and RML-86/RML-96 were taken as vertical factor whereas five densities viz. 55,555 ha-1(D1), 66,666 ha-1 (D2), 77,519 ha-1 (D3), 87,719 ha-1 (D4) and 98,039 ha-1 (D5) in combination with two doses of NPK fertilizers i.e. recommended and rational as horizontal factor. Recommended dose of NPK for maize was 120:60:40 kg ha-1 and the rational doses for above mentioned densities were calculated based on bench mark of fertilizer recommendation for 53,333 plants ha-1. Derived rational doses of NPK for D1, D2, D3, D4 and D5 were 125:63:42, 150:75:50, 174:87:58, 197:99:66, 221:110:74 kg ha-1 respectively. Genotypic variation of two tested hybrids for growth, yield attributes and grain yield were found statistically similar. However, planting the hybrids in various densities and fertilizer doses significantly influenced grain yield ranging from 5.63 to 7.91 t ha-1. Significantly higher grain yield (7.91 t ha-1) and benefit cost ratio (2.21) were observed when plant population was maintained at 77,519 ha-1 with fertilizer dose 174:87:58 NPK kg ha-1. Applying fertilizer as rational dose enhanced the yield up to the density of 77519 plants ha-1 then the yield gradually declined as the density increased. Whereas recommended dose of fertilizer with increasing plant density from 55,555 to 87,719 ha-1 had statistically similar yield and declined more at 98039 ha-1. The present recommended dose of fertilizer application is inadequate for higher plant density to increase the grain yield of hybrid maize

This study used a randomized complete block design (RCB) to evaluate the effect of various doses of organic fertilizer on the growth and yield of peanut plants. This research involved seven treatment units, each with a unique combination of inorganic and organic fertilizers. Each treatment was repeated four times, so there were 28 treatment units. Each unit comprises 16 plants carefully selected and managed to ensure consistent growing conditions. Four plants were taken from each unit as samples for analysis, and 112 sample plants were used to collect growth data and other relevant variables. Peanut cultivation in Indonesia faces serious challenges, such as reduced productivity due to prolonged drought and inadequate agricultural practices. This research aims to determine the impact of lowering the dose of inorganic fertilizer and increasing the use of organic fertilizer on the growth and yield of peanuts. The results showed a significant effect of various fertilizer combinations on growth parameters. Treatment P5 (a combination of inorganic and organic fertilizer) gave the best results in vegetative observations. In contrast, treatment P4 (a combination of inorganic and organic fertilizer) was superior in yield and pod weight. These findings emphasize the importance of implementing integrated fertilizers in peanut cultivation to improve agricultural sustainability. This research provides valuable insights for farmers and researchers in developing more efficient and environmentally friendly farming practices and supporting increased productivity of peanut plants in various environmental conditions

Fertilizer is a supporter of soil growth and enrichment so as to increase agricultural production while at the same time improving environmental quality. The use of fertilizer is adjusted to the amount of land needed and the number of seeds purchased. In reality, fertilizer for shallots is still difficult to obtain, and prices are still high above retail prices, making shallot farmers want fertilizer subsidies from the government even though the subsidies provided are still inadequate and uneven. The purpose of this study was to analyze the effect of providing fertilizer on land area, seed needs, and prediction of fertilizer needs for shallots. The results of this analysis resulted in the design of business processes in the supply of fertilizers using the Business Process Reengineering Life Cycle method. Primary data collection was carried out using questionnaires and interviews with shallot farmers. The results showed that the production of fertilizer needs in accordance with the area of land and the number of seeds used. Therefore, efforts to increase the competitiveness of shallots can be carried out by proposing the BPR Life Cycle, so that the proposed framework is expected to be realized in order to increase productivity and build farmer institutions to realize further agricultural development.

Full textAbstract:
Agriculture is the backbone of Ethiopia’s economy. It is responsible for 35.45% of the country’s total domestic output. This means that the sector is critical for enhancing the lives of the wider population. Despite its importance, Ethiopia’s agricultural sector produces little. The Ethiopian government has focused on increasing the usage of organic fertilizers to improve this and overall economic growth. Organic fertilizer use is still inadequate in most parts of Ethiopia, including Moretna Jeru District in North Shewa Zone, Amhara region. The main objective of this study was to investigate factors that influence the adoption (use) of organic fertilizer technology in Moretna Jeru District. For this study, primary data were acquired from 192 smallholder farmers who were chosen at random throughout the 2020/21 growing seasons. The factors influencing organic fertilizer adoption were investigated using a probit model. Farmers’ characteristics such as extension contact, number of livestock, landownership via title deed, and household size have a favorable and significant impact on organic fertilizer usage. Farmers should be encouraged to use manure technology. This would be attainable if the government, nongovernmental organizations, and other stakeholders focused more on improving extension services and providing better information and training on the use of organic fertilizers.

Full textAbstract:
Traditionally, broadcast or foliar fertilizer applications sufficed to improve the nutrition of many irrigated, deciduous fruit orchards in western North America. Recent developments, including adoption of low-pressure, micro-irrigation systems and planting at higher densities (especially for apples), have increased interest in controlled application of fertilizers directly with irrigation waters (fertigation). The possibility of using fertigation to synchronize fertilizer application and plant nutrient uptake seems attractive as environmental concerns to minimize leaching of nutrients (especially N) to groundwater increase. Recent fertigation research in western North America will be reviewed and compared to traditional fertilizer application methods to assess the potential of fertigation to overcome inadequate nutrition. Emphasis will be placed on the use of soil solution monitoring to assess changes in soil NPK status. Tree response will be illustrated by studies in high-density orchards where N, P, K, Ca, B, or Zn have been fertigated.

Full textAbstract:
The study investigates actor relationships in subsidized fertilizer programs within Indonesian rice production hubs. It aims to comprehend roles and interactions among actors in budget allocation, fertilizer distribution, policy oversight, and farmer involvement. The research employs a descriptive qualitative approach, analyzing how institutional practices and hierarchies impact the subsidized fertilizer market. The study focuses on Indramayu and Karawang Regencies in West Java and Sidenreng Rappang (Sidrap) and Wajo Regencies in South Sulawesi, all significant rice production centers. Data was gathered through in-depth interviews involving central, regional, distributor, store actors, and farmers. Results reveal collaboration and competition as primary relationship modes in the subsidized fertilizer program. Cooperation exists among institutional players at the central level during budget deliberations, while relationships emerge when actors unite to advocate for budget adjustments or specific fertilizer types. Factors like discourse, institutional practices, and capitalist interests shape these inter- actions. Discourse might favor chemical or organic fertilizers. Farmers occupy a relatively marginalized position in actor conflicts, warranting increased policymaker attention. Although the government seeks improvements, farmers still face challenges such as inadequate doses, delays in distribution, and financial constraints

Full textAbstract:
Low crop yields as a result of inadequate application of fertilizer remains to be a challenge limiting optimum crop production especially among smallholder farmers in Kenya. The government of Kenya, under The National Accelerated Agricultural Inputs Access Programme (NAAIAP), introduced subsidized fertilizers aimed at increasing crop productivity. Despite these initiative, there has not been much achievements as far as general increase in crop yields and especially maize crop yields in the country is concerned. This study therefore sought to investigate the factors affecting the access and the use intensity of subsidized fertilizer among smallholder farmers in Kenya with the case of Trans Nzoia County. The specific objectives of the study were to establish the factors affecting the access to subsidized fertilizers and to assess the factors affecting the intensity of fertilizer used. This study employed cross -sectional survey using structured questionnaires to collect the data from 384 farmers who had been selected using multi-stage sampling technique. The data was analyzed econometrically using a double hurdle model which combined a probit model and a truncated regression model. The findings show ed that age, access to extension services, land size, distance to market, household size and non-farm income significantly affected the accessibility of subsidized fertilizer to the farmers while the intensity of subsidized fertilizer use was significantly determined by age, land size, access to extension services and non-farm income of household head. The study concluded that the government should target the smallholder farmers and consider their factors when formulating policies for distribution of subsidized fertilizers as they are the intended beneficiaries of the program.

‘Microbes in agriculture and biotechnology’ considers the applied microbiological research to improve soil fertility and combat plant diseases, as well as the development of genetically modified (GM) food, which may help to reduce the cost of modern agricultural practices and their contribution to climate change. Natural mechanisms that control soil fertility are inadequate to the task of supporting modern intensive agriculture and a human population that may exceed nine billion in 2050. Intensive grazing of cattle on deforested land is similarly unsustainable. Even in areas where soils are exceedingly rich, crop productivity falls without soil amendment with organic matter and inorganic fertilizers.

Water, a ubiquitous molecule (H2 O), is the essence of life on Earth (Morrison et al., 2020). Its unique physicochemical properties, notably its exceptional solvent power, make it indispensable for all biological processes (Rubilar et al., 2020). However, the availability of clean freshwater, vital for human and ecosystem health, is increasingly threatened by anthropogenic (human&#2;caused) contamination (Gitis and Hankins, 2018; Hodges et al., 2018). Several human activities contribute to this global challenge. Inadequate wastewater treatment facilities allow untreated sewage to enter waterways, introducing harmful pathogens and nutrients that disrupt aquatic ecosystems. Industrial discharges often contain hazardous substances, heavy metals, and persistent organic pollutants, further compromising water quality (Umar et al., 2019a; Elbeltagi et al., 2021). Unsustainable agricultural practices, including excessive fertilizer use and pesticide discharge, also contribute to water pollution. Additionally, the dumping of waste materials, including plastics and radioactive elements, into oceans and other water bodies poses a significant long-term hazard (Jiang et al., 2019; Edokpayi et al., 2020)

With the rise of civilization, open-field agriculture is encountering significant challenges, particularly the decrease in per capita land availability. In 1960, when the global population was 3 billion, the per capita land was 0.5 hectares. However, with the current 6 billion people, it has dwindled to only 0.25 hectares, and projections indicate it will further decline to 0.16 hectares by 2050. This decline is exacerbated by rapid urbanization, industrialization, and the melting of icebergs due to global warming, which further reduces arable land for cultivation. Another issue is the saturation of soil fertility and the stagnation of productivity despite increased fertilizer usage. In addition, certain cultivable areas suffer from poor soil fertility, with limited opportunities for natural fertility build up by microbes due to continuous cultivation. Frequent drought conditions, unpredictable climate, and weather patterns, rising temperatures, river pollution, inadequate water management, excessive water wastage, and declining groundwater levels also pose threats to conventional soil-based agriculture and food production. In light of these circumstances, relying solely on open-field agricultural production will soon make it impossible to sustain the entire population. Consequently, soil-less culture has gained relevance in addressing these challenges. This method involves cultivating plants without soil, utilizing improved techniques that conserve space and water. Soil-less culture has demonstrated promising results worldwide as a means of food production. This paper discusses the way to automate a small-scale hydroponics system by building a computerized system consisting of: Microcontroller pH sensor EC sensor (to measure nutrient level in solvent) Temperature sensor Fluid pumps connected to pH- and nutrient reservoir

The relentless growth of the global population, compounded by the adversities posed by climate change, has triggered an unprecedented demand for sustenance. This burgeoning need places an imperative on the agricultural sector to adopt practices that are both sustainable and efficient. Traditional farming methods, marked by inefficiencies and environmental ramifications, prove inadequate in meeting this escalating demand. Inresponse, precision farming emerges as a transformative solution, centering on data-driven decision-making and the optimization of resources.This groundbreaking whitepaper meticulously navigates the intersection of precision farming and augmented reality (AR) technology, showcasing a paradigm shift in agriculturalpractices. AR, a revolutionary tool overlaying digital insights onto the physical world,empowers farmers with real-time information on soil conditions, crop health, and moisture Levels. Harnessing AR's capabilities, farmers gain unprecedented control over irrigation and fertilizer applications, minimizing waste while maximizing yields. The paper dives deep into the modern challenges of agriculture, articulates the substantial benefits of precision farming, and underscores AR's transformative potential in surmounting these challenges. Precision farming, elucidated as the fusion of technology to gather and analyze data on parameters like soil moisture and weather conditions, is detailed with utmost clarity. In contrast to the antiquated one-size-fits-all approach of traditional farming, precision farming, facilitated by real-time data and analytics, enables bespoke crop management.This optimization minimizes resource usage, curtails waste, and augments productivity to Unparalleled levels.The whitepaper seamlessly dissects precision farming into two indispensable components:data capture and data visualization. The Internet of Things (IoT) emerges as the linchpin for data capture, employing sensors that collect real-time data transmitted to a centralized platform for astute analysis. Concurrently, AR, the second component, emerges as the pivotal interface, empowering farmers to seamlessly visualize and interpret data for judicious decision-making. In the current corporate panorama, stalwarts like Augmenta and Grow Glide, coupled with potential contributors like Rams Creative Technologies Pvt. Ltd. and emerging entities likeInfosys Limited, stand as vanguards propelling technological advancements to bolster precision farming. However, the potential for widespread AR adoption in precision farming faces impediments. Concerns regarding the safety and health risks associated with AR hardware, coupled with formidable development costs, and a prevailing lack of awareness pose substantial challenges.

The global demand for animal-sourced foods has led to an expansion and intensification of livestock production, resulting in complex environmental and ecological challenges. In the 1960s and 1970s, leys played a crucial role in cropping systems. However, the pursuit of increased production to meet the needs of a growing global population has driven specialization in agriculture. This shift has involved widespread use of inputs like fertilizers and herbicides, narrowing agricultural focus in high-income regions. Consequently, it has reduced agro-diversity and fragmented once-diverse landscapes, leading to biodiversity loss, diminished pollinator habitats, and increased susceptibility to pests and diseases, all threatening global food security. Despite advancements in breeding for crops like maize, translating these gains into practical agriculture has been limited. This has resulted in too few crops cultivated under high-intensity conditions, leaving current food systems ill-prepared for climate change. A paradigm shift towards resilient food systems, prioritizing increased yields and ecological efficiency, is essential to align with the EU’s farm-to-fork strategy. This chapter explores agricultural challenges and underscores the need for sustainable solutions. It delves into the integration of crop and livestock systems, an innovative approach that optimizes food production while reducing reliance on synthetic inputs. This approach not only improves the conversion of plant-bound nutrients into animal-source food but also nurtures soil vitality. The discussion extends to grasslands and multispecies leys, highlighting their role in promoting biodiversity, enhancing soil health, and offering carbon sequestration opportunities. A compelling case study illustrates the benefits of a grass-clover ley-based integrated crop-livestock system (ICLS), impacting water and air quality conservation, climate change mitigation, agro-biodiversity enhancement, and land use efficiency. Despite evidence that innovative farming practices can enhance environmental benefits, farmers often receive inadequate compensation due to the lack of proper valuation. Additionally, the chapter provides estimates of avoided environmental costs associated with a typical ICLS compared to a conventional dairy system. In conclusion, a transformative shift in agricultural practices, which prioritizes sustainability, regional circularity, and the preservation of natural and social capital, is advocated.

Full textAbstract:
The use of chemical fertilizers as a supplemental source of nutrients has been on the increase but they are not applied in balanced proportion by most farmers [1]. Also, fertilizer requirements of the mixed intercropping systems have been a matter of conjecture; some studies had suggested that fertilizer requirements of the dominant component be applied [2], others recommend that the sum of the sole crop requirements, be applied [3]. Teriah [4], however, stated that both practices have proved either inadequate or wasteful. In this experiment the effects of different rates of NPK 15-15-15 fertilizer application on growth and yield of hot pepper and Egusi melon in an intercropping system was examined to determine optimum rate for production. The experiment was carried out at the Teaching and Research Farm of the Federal University of Agriculture Abeokuta, in the south western part of Nigeria. It took place from March to October 2017 during the growing season. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 5 treatments (fertilizer rates) and 3 replicates. Treatments were; 0, 100, 200, 300 and 400 kg/ha of NPK 15-15-15 applications. Plot size was 3m by 3m with a 1.5m gang way round each plot to reduce inter-plot effect. Data were collected on growth parameters at 6 weeks after treatment (WAT) and continued at two-week intervals until 10 WAT. Four plants each of pepper and Egusi melon from the inner rows were randomly selected and tagged for the purpose of data collection. Data on yield were also collected at ripening. Analysis of variance (ANOVA) was carried out on each observation and the Least Significant Difference (LSD) was used for means separation (P≤0.05). The effects of fertilizer rates showed significant difference on pepper plant height, number of leaves, number of branches and leaf area. However, there was no significant difference in the effect of fertilizer rate on days to 50% flowering of pepper. Number of vines and vine length of Egusi melon were significantly different in their responses to fertilizer rates but the leaf area and days to 50% flowering of melon were similar at the various treatment levels. Meanwhile, total fruit yield of pepper, number of Egusi melon pods per hectare and the dry matter yield of Egusi melon showed significant difference. It was concluded from the study that the growth and yield of pepper and Egusi melon in intercrop increased with increase in fertilizer rate up to 400Kg/ha of NPK (15:15:15). However, higher fertilizer application rates should be explored in future studies for a better yield increase. These studies should be carried out with various compositions of inorganic and organic fertilizer application rates to ensure sustainable fertilizer application and to also preserve the natural fertility of the soil.

The industrial cultivation of American cranberry (Vaccinium macrocarpon Aiton) in Latvia was started during last 20 years with total plantings of more than 125 ha today. As a native wetland plant, commonly cranberries grows on poor, acid soils and are characterized as nutrients low requiring crop, however, balanced plant nutrition is vitally important to realize the full potential of cranberries as crop, to ensure adequate growth and yield production. Previous results obtained by authors from different cranberry producing plantings in Latvia frequently showed inadequate cranberry tissue supply with N and P. A field trial were established to examine the impact of N and P fertilizer rates on cranberry yield, fruit quality, morphological factors, and mineral element supply. Field experiments on cranberry cultivar �Bergman� were conducted during 2019 cropping season in a commercial plantation established on an excavated peat bog in Latvia. The cranberries received five levels of N (0 to 40 kg N ha-1) and P (0 to 30 kg P ha-1) as well as N and P treatment combinations applied in spring. Cranberry leaf analyses and soil (peat) testing were used as a diagnostics tool to reveal nutrient (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B), soil pH and EC status. In general, crop characters were significantly influenced by different levels of N and P. As expected, the results showed that combined N and P treatments with the highest rates: N30/P20 and N40/P30 resulted in the highest yields and yield parameters, as well as ensured optimal N and P concentrations in cranberry tissues. It should be noted that the rates of applied fertilizers were environmentally safe as the nutrient concentrations recommended for peat growing medium were not exceeded.

For more than a decade years, the authors have conducted extensive investigation and analysis on these accidents and consider that apart from the causes of man-made quality out-of-control and technical level, another major cause is the absence of experience accumulation of some medium environments induced failure accidents for design standards and codes, design units and designers, therefore, it is unable to prevent and control in-service risk factors at the design stage. Since 2003, we have conducted risk-based inspection and analysis of industrial pipelines of all types of units in about eighty large-scale oil refinery plants, chemical plants and chemical fertilizer plants under the jurisdiction of SINOPEC and PetroChina according to API581, API571 etc. in cooperation with Bureau Veritas, France (BV). Through these analyses, we have found out the major failure modes, mechanisms, likelihood and consequences of petrochemical industrial pipelines, and we also consulted the original design and installation documents of all pipelines, it is found that most of the high failure risks of petrochemical industrial pipelines are induced by inadequate consideration to environment induced failure mechanisms at the design stage. In order to avoid repetitive occurrence of these accidents, suggestions on improvement of design and manufacture methods in China are proposed in this paper, that is, the experience of in-service environment-related failures should be fed back to the organizations of design and manufacture standards, design institutions and designers by some effective means, and set up the design and manufacture platform based on risks and life in China, so as to control the risks of pressure pipelines away from accident over the whole life through such measures as reasonable material selection, structural optimization design, selection of reasonable manufacturing and installation process etc. at early stage of design and manufacture.

Understanding soil fertility variability in cultivated areas provides important insights for the rational use of soil amendments and fertilizers. This study aims to evaluate changes in the spatial variability of soil chemical properties resulting from intensive vegetable cultivation over more than 50 years in mountain agroecosystems in Nova Friburgo, Rio de Janeiro. The creation of maps for each attribute allowed visualization of its spatial distribution in the area, which is not possible when using only descriptive statistical analysis. The soil's chemical and physical attributes showed spatial variation, with P, K+, Mg+2, Al+3, base saturation (V%), and silt displaying high variability, while Ca+2, Ca+Mg, H+Al, organic carbon, CEC, sand, and clay showed medium variability. However, pH demonstrated low variability. Two main sources of variation in fertility spatial distribution were identified: one characterized by topography and another associated with agricultural activities, which, through intensive use of agricultural inputs, are contributing to increased soil fertility. Another factor is associated with inadequate soil management and topography, which cause the transport of finer soil particles and their accumulation in lower parts of the terrain, where enrichment in P, K+, Ca+2, Mg+2, and organic carbon levels is observed. The evident acidity in agricultural soils is due to high natural acidity and farmers' infrequent use of liming. The soils showed values considered high or very high for P (88%) and K+ (65%) in the study area. These values are directly associated with excessive use of poultry litter and soluble phosphate and potassium fertilizers during vegetable production.

Waste management in Brazil is guided by the National Solid Waste Policy (PNRS) (IBAMA, 2022). The PNRS foresees the elimination of landfills and the disposal of urban solid waste (MSW) in landfills only when there is no potential for reuse, including recycling and reverse logistics (BONJARDIM; PEREIRA; GUARDABASSIO, 2018, p. 315). Organic solid waste (RS) can be transformed into fertilizers (ARAÚJO; CERQUEIRA; CARNEIRO, 2020), and inadequate disposal can cause sanitary and environmental problems (HECK et al., 2013). MSW is classified by Law No. 12,305/2010 (BRASIL, 2010) into household waste (RDO) and public waste (RPU). In this study, RS was classified as wet solid household waste (RSDU) and UPR, according to SNIS (2022). Composting, a natural process of degradation of organic matter, is currently used to manage organic RS, using techniques to accelerate decomposition and produce organic compounds of social interest (CRIVELARO; MOREIRA; DA SILVA, 2018, p. 91). This study hypothesized that the implementation of a composting yard at the University of Sorocaba is viable, both technically and economically, to manage part of the RS generated at the Campus Cidade Universitária Prof. Aldo Vannucchi. The objective was to develop an operational pilot project for an organic RS composting yard for the university, identifying sources of organic RS (RSDU and RPU), adapting a methodology for composting, determining performance indicators and carrying out a cost analysis of the project.

Growth stimulation of perennial ryegrass by plant growth promoting bacteria under limited nutritional conditions.

Full textAbstract:
Although there are many studies on plant growth promotion carried out using bacteria on various crops, there is scarce information on the effects of PGPR on the growth of perennial ryegrass (Lolium perenne) cultivated in Colombian high tropics. Ryegrass is one of the most widely cultivated grass in Colombia, and it used as a nutritional source for livestock in intensive dual purpose, milk and meat production systems [1]. Several factors affect pasture degradation, including the following: (i) low planting density before grass initiated, (ii) forage species unsuitable for local conditions, and especially (iii) decrease in soil fertility due to inadequate use of fertilizers [2]. Therefore, the maintenance of pasture growth becomes a pivotal challenge to the sustainable management of Colombian tropical soils under livestock production.

Full textAbstract:
Millets have long been a staple of the regional diet in Northeast India because of their durability and high nutritional value. However, the rise in consumption of fine cereals, along with a subpar production system and inadequate compensation for millet farmers, have led to the decline of millet consumption and production. The low volume output is exacerbated by the lack of access to good-quality traditional seeds, fertilisers, and effective farming methods, coupled with changing patterns of climate. Furthermore, poor market demand and a lack of pro-poor policies of the government make millet growing even more difficult. Farming communities have few options for generating revenue since limited efforts have been made to market and link millet-based products to markets. Thus, there is a need to support existing farming practices that generate agrobiodiverse landraces, develop climate-resilient cultivars, and facilitate platforms for the value addition of the product. The existing primary processing of millets is labour-intensive and the lack of proper storage facilities results in poor-quality grains fetching low market prices. Thus, there is a need to develop infrastructure and build the capacity of farmers and other stakeholders along the millet value chain.
