Proper nourishment is fundamental for satisfactory crop growth and production. However, for efficient crop production, it is important to understand the soil environment, to recognize the limitations of that environment, and to ameliorate them where possible without damaging the soil quality. Soil testing and fertilizer recommendation facilities (STFRF) can help farmers to achieve environmental and economic sustainability by assisting them in recognizing their soil condition, reducing agrochemicals usage, using an appropriate amount of fertilizer, minimizing input costs, and achieving higher yield. These facilities are not new in the context of Bangladesh, yet the adoption rate among farmers is low and its determinants have rarely been empirically tested based on microlevel data. Therefore, this study examined those factors underlying the adoption of soil testing and fertilizer recommendation facilities using field surveyed data of 176 individual farmers. Our evidence shows that young farmers with less farming experience are more likely to adopt these facilities. Additionally, being small-scale farmers, having higher education, having more farming income, and having more knowledge about these facilities and the fees of these facilities were found to have a significant effect on the adoption. On the other hand, gender, land ownership, and secondary income were found to be insignificant with regard to the adoption of soil testing and fertilizer recommendation facilities. Our results also revealed that most adopter farmers not only focused on profitability, but were additionally concerned with environmental well-being.

AbstractIn arid areas of western Rajasthan, major constraints responsible for low plant production include low and erratic rainfall, high evaporation, and low soil fertility, particularly with respect to organic carbon and nitrogen. These problems lead to acute shortages of grain, fodder and fuelwood. Sustainable crop and biomass production can be achieved through adoption of agroforestry, silvipastoral and agrihorticultural systems. Integrated nutrient and moisture management practices can help in controlling pathogens and in improving the soil environment for higher sustained production.

Soil Water Movement

Of the many forms of above- and below-ground stresses facing agriculture production, physical soil limitations are generally among the most persistent and least amenable to amelioration. Fine textured heavy soils have physical constraints that severely affect soil and plant health and yield parameters and there is a need to study the problems of these type of soils and find possible measures to ameliorate these problems. Reasons for these problems along with possible preventing measures have been discussed. These soils have severe soil aeration problem due to restricted soil water movement within the profile. The affects of these constraints on crop growth and productivity were highlighted. For efficient crop production, it is important to understand the soil environment in which plants grow, to recognize the limitations of that environment and to ameliorate where possible without damaging the soil quality. For satisfactory plant growth, it is essential that the soil provides a favourable physical environment for root development that can exploit the soil sufficiently to provide the plants needs for water, nutrients and anchorage.

AbstractAgricultural intensification continues in Africa in attempts to meet the rising food demands of the equally rising population. However, most arable lands in the region are characterized by nutrient deficiency and over-reliance on synthetic fertilizers which consequently contributes to increased production costs, environmental pollution, and global warming. Decades of research on plant–rhizobacterial interactions have led to the formulation and commercialization of rhizobacterial biofertilizers globally for sustainable soil and crop health. Nevertheless, this promising technology has not received much attention in Africa and remains largely unexplored due to several constraints. This article discusses the practical applications of rhizobacterial biofertilizers for sustainable crop production in sub-Saharan Africa. The challenges of soil infertility and the use of conventional synthetic fertilizers in crop production in Africa are critically evaluated. An overview of the potential of rhizobacteria as biofertilizers and alternatives to synthetic fertilizers for soil fertility and crop productivity in the continent is also provided. The advantages that these biofertilizers present over their synthetic counterparts and the status of their commercialization in the African region are also assessed. Finally, the constraints facing their formulation, commercialization, and utilization and the prospects of this promising technology in the region are deliberated upon. Such knowledge is valuable towards the full exploitation and adoption of this technology for sustainable agriculture for Africa’s food security.

Microorganisms make a deal in the field of agro-ecosystem and environment (7). Continuous in global human population may hamper in the field related to soil fertility, (39) energy crisis, food security for further generation (40). These conditions could be regulated by using synthetic fertilizers (8). Although synthetic fertilizers are effective but have deleterious effect on the field. This article focuses on the role of Cyanobacteria with context to the field of crop production (13). Cyanobacteria aka blue green algae belongs to aprimordialdescent of photo-oxygenic bacteria. They also form symbiotic association capable to fix atmospheric Nitrogen into utilise form and make it available to the plants. Its extra ordinary development rate shows its use in the field of biotechnology, medicine, agriculture, bio energy. The exo-polysaccharide of Cyanobacteria balances soil ecology and they have the ability to compete with flora and fauna. Several Cyanobacteria have high biomass yield, generation of useful by-products, bio fuel and enhancing sustainable development in the field of science. In this review article describes the latent use of the bacteria in the crop field, different area of science field and mass production of cyanobacteria bio fertilizer in agriculture to overcome the use of chemical fertilizers.

AbstractThis paper presents EuropeAgriDB v1.0, a dataset of crop production and nitrogen (N) flows in European cropland 1961–2019. The dataset covers 26 present-day countries, detailing the cropland N harvests in 17 crop categories as well as cropland N inputs in synthetic fertilizers, manure, symbiotic fixation, and atmospheric deposition. The study builds on established methods but goes beyond previous research by combining data from FAOSTAT, Eurostat, and a range of national data sources. The result is a detailed, complete, and consistent dataset, intended as a basis for further analyses of past and present agricultural production patterns, as well as construction of scenarios for the future.
