Restoring Soil Fertility through Organic Amendments: Impacts on Agriculture and Human Health

The application of organic amendments in agriculture has become a vital approach to addressing key challenges in Indian agriculture, such as fragmented landholdings, inadequate irrigation, and declining soil fertility. These amendments, which are added to soil to enhance its physical, chemical, and biological properties, play a significant role in promoting sustainable farming. Organic amendments like compost, manure, and green manure serve as excellent sources of organic carbon and essential nutrients. They improve soil structure, enhance drainage, and facilitate nutrient cycling while mitigating soil alkalinity and fostering microbial activity, thereby supporting overall soil health. Research highlights the effectiveness of organic amendments in improving soil quality. Organic amendments also offer notable benefits for human health by reducing dependence on synthetic fertilizers and minimizing toxic residues. They decrease the risks of heavy metal contamination and pesticide exposure. Adopting organic amendments supports the broader goals of sustainable agriculture by enhancing biodiversity, improving soil fertility, and reducing environmental and health risks. Nevertheless, further research is needed to refine these practices, optimize their application, and thoroughly evaluate their effects on human well-being and agricultural productivity. Organic amendments offer a promising solution to meet the growing food demands of an expanding population while maintaining ecological balance and ensuring food security.
