Summary: Macronutrient-enriched biochars have the potential to recycle nutrients from waste, improve soil fertility, reduce fertilizer consumption, and promote sustainable agriculture. The recent focus has been on exploring different methods for producing macronutrient-enriched biochar fertilizers, and there is a need for further scientific understanding and advancement in this field. This review provides crucial information about the production and use of nutrients-enriched biochars, as well as their potential challenges and future perspectives. The main focus of these biochars is on nitrogen and phosphorus, and they can enrich up to 10%, 15.32%, and 25.85% of total N, P, and K respectively. However, more research is needed on the bio-labile and plant available fractions of these nutrients. Overall, the prospects of nutrients-enriched biochars for sustainable agriculture have gained momentum, and further engineered biochars hold great potential for specific soil-plant-environment systems.

Summary: Soil salinization is a significant problem for crop production, but by using stress tolerant plant growth promoting rhizobacteria, saline soil fertility can be improved. This study identified two bacteria, Pantoea dispersa and Pseudomonas aeruginosa, from the rhizospheric microbiota of stress tolerant Eichhornia crassipes that showed high solubilization of phosphate under salt stress. The mechanisms of phosphorus solubilization and adaptive responses to salt stress were analyzed, revealing the potential of P. dispersa PSB1 in improving soil fertility in saline conditions.

Summary: Long-term use of toxic pesticides has had adverse effects on the environment and human health. Microbe-mediated biodegradation is an effective strategy for removing contaminants in agriculture and promoting environmental sustainability. A Pseudomonas plecoglossicida strain (MBSB-12) isolated from imidacloprid-contaminated tea garden soil showed high efficiency in degrading the pesticide, reducing 87% of extractable imidacloprid from treated soil in 90 days. Further investigation is needed to understand the molecular mechanism of imidacloprid degradation by this strain.

Summary: The continuous decline of earth's natural resources and increased use of hazardous chemical fertilizers are posing great concerns for the future of agriculture. Biofertilizers are gaining importance as a promising alternative to hazardous chemical fertilizers in achieving sustainable agriculture. They play a key role in enhancing crop yield, maintaining soil fertility, and providing essential nutrients in soluble forms for plant growth.

Summary: The intensification of agricultural production in response to the global population increase and the growing demand for food has raised concerns about environmental impacts. Microalgae have emerged as a promising and sustainable alternative to agrochemicals, offering benefits such as improved soil fertility and reduced reliance on synthetic fertilizers. They also have the ability to sequester carbon and contribute to sustainable agriculture by reducing greenhouse gas emissions.

Summary: The aim of this study was to evaluate the effects of silicon fertilization on phosphorus fertilizer use efficiency in acidic tropical soil, and to investigate the potential of using glacial rock flour as a source of silicon. The results showed that glacial rock flour can rejuvenate strongly weathered agricultural soils, improve stress tolerance in plants and ultimately increase yields, but it does not improve phosphorus availability in acidic soils.

Summary: Agriculture is crucial for many economies, but traditional soil fertility classification and fertilizer application methods are expensive and pollute the environment. This study explores the use of machine learning and deep learning techniques in soil fertility classification and examines their potential to reduce costs and improve soil fertility.

Summary: Due to climatic constraints in semi-arid areas, cultivated soils have low organic matter, leading to limited crop yield. Conservation tillage systems, such as no tillage, no tillage with straw return, and straw incorporation into the field, are considered effective in preserving soil resources and sustaining soil productivity. This study aimed to investigate the impact of these conservation tillage systems on soil properties and spring wheat yield. Results showed that conservation tillage significantly improved soil physical, chemical, and biological properties, as well as increased wheat yield, compared to conventional tillage.

Summary: Microorganisms produce microbial volatile organic compounds (mVOCs), which act as communicators through inter and intracellular signaling pathways. These chemically diverse mVOCs play crucial roles in plant interactions, modifying physiological and hormonal pathways to enhance growth and production. Additionally, mVOCs alleviate stresses and elicit plant immunity, making them an effective alternative to chemical fertilizers and pesticides. This review summarizes recent research on mVOCs and their roles in inter and intra-kingdom interactions, highlighting their potential for improving soil fertility, food safety, and security in sustainable agriculture.

Summary: Soil degradation poses a threat to agricultural production and soil multifunctionality. Efforts are being made to promote sustainable soil management through consensus among science, policy, and practice. In Germany, a shortlist of seven consensual measures for agricultural soil management has been compiled, including structural landscape elements, organic fertilization, diversified crop rotation, permanent soil cover, conservation tillage, reduced soil loads, and optimized timing of wheeling. The implementation barriers primarily include economic and technological factors, with a need for a systemic diversification of the production system.

Summary: Excess water and soil salinity are abiotic stresses that limit plant access to soil nutrients and reduce crop production in coastal agricultural lands. This study investigates the effects of water salinity on phosphate mobility at the soil-water interface, finding that higher salinity enhances phosphate adsorption to soil particles. Additionally, the enhanced adsorption under elevated salinity and alkaline pH conditions suggests that co-adsorption with divalent cations plays a major role in phosphate binding to soil minerals.

Summary: Organic farming typically results in lower crop yields compared to conventional farming, with the success depending on local climate and crop and soil management. A long-term study in Denmark showed that the legacy effects of soil fertility management on crop yield, particularly through nitrogen inputs from cover crops and manure, are significant. Organic cropping systems should focus on weed suppression, soil fertility improvement, and targeted manure inputs to enhance nitrogen uptake for optimal yields.
