 Soil amendments play a pivotal role in overcoming continuous cropping obstacles in soybean systems by restoring soil health, boosting nutrient cycling, and strengthening the resilience of microbial communities. Continuous soybean cultivation often leads to soil fatigue, nutrient depletion, and an imbalance of beneficial and pathogenic microbes. By incorporating amendments such as organic compost, biochar, manure, and mineral conditioners, farmers can stimulate beneficial microbial activity, enhance soil enzyme functions, and suppress harmful pathogens. These amendments improve soil structure, increase organic matter, and create a more stable rhizosphere environment, allowing soybeans to better withstand stress. Strengthening microbial resistance not only reduces disease incidence but also promotes root vigor, nitrogen fixation efficiency, and overall plant productivity. Ultimately, soil amendment strategies serve as a sustainable and nature-based solution to revitalizing degraded ...

 Competitive adsorption between phosphate and dissolved organic carbon (DOC) in iron-rich soils plays a crucial role in regulating nutrient availability, soil fertility, and biogeochemical processes. In these environments, iron oxides provide abundant reactive surfaces that strongly bind both phosphate and DOC, often leading to competition for adsorption sites. This interaction influences phosphorus mobility, potentially reducing its availability for plant uptake when DOC occupies key sorption sites. Conversely, phosphate can displace weakly bound organic molecules, altering carbon stabilization and microbial activity. The extent of competition is governed by soil pH, redox conditions, DOC composition, and the crystallinity of iron minerals. Understanding these mechanisms is essential for improving phosphorus management in agricultural systems, predicting carbon cycling under changing environmental conditions, and developing strategies that enhance nutrient-use efficiency while pre...

 Soil infiltration—the process through which water enters and percolates through the soil profile—varies widely across soil reference groups, textures, and land-use types. This variability is shaped by inherent soil characteristics and external ecosystem pressures. Coarse-textured soils such as sandy soils generally exhibit higher infiltration rates due to larger pore spaces, while fine-textured clay soils tend to have slower infiltration because of compacted micropores and higher water-holding capacity. Soil reference groups like Fluvisols, Andosols, or Cambisols often display strong infiltration potential owing to their porous structure and organic matter content, whereas Vertisols and Luvisols typically show restricted infiltration due to swelling clays and dense subsoils. Land-use practices further influence infiltration behaviour: natural forests and well-managed agroforestry systems enhance infiltration through increased litter cover, root activity, and soil biological proces...

  Global food and nutrition security is increasingly challenged by the accelerating impacts of climate change, which affect agricultural productivity, food availability, and dietary quality across regions. Rising temperatures, shifting rainfall patterns, and frequent extreme weather events disrupt crop growth, reduce soil fertility, and increase pest and disease pressures, thereby threatening stable food supplies. Climate-induced declines in nutrient-rich crops further compromise dietary diversity and the nutritional well-being of vulnerable populations. Ensuring global food and nutrition security in this changing climate requires an integrated approach that promotes climate-resilient crop varieties, sustainable soil and water management practices, diversification of farming systems, and improved post-harvest technologies. Strengthening early warning systems, enhancing farmer capacity, and advancing policy frameworks aimed at sustainable, equitable food systems are essential for re...

  Integrated nutrient management (INM) for sustainable crop productivity emphasizes the balanced and efficient use of organic, inorganic, and biological nutrient sources to maintain soil fertility while ensuring long-term agricultural sustainability. INM combines fertilizers, compost, manure, crop residues, green manures, and microbial inoculants to optimize nutrient availability and improve soil structure, microbial activity, and nutrient-use efficiency. This approach helps reduce dependency on chemical fertilizers, minimize nutrient losses through leaching or volatilization, and enhance soil organic carbon, leading to better water retention and improved root growth. By integrating site-specific nutrient management, precision application, and crop rotation practices, INM supports stable yields, enhances crop resilience to stress, and promotes ecological balance. Ultimately, integrated nutrient management not only boosts agricultural productivity but also contributes to long-term ...
