Impact of Microplastics in Agricultural Soil on Nutrient Recycling and Fertility

Microplastics (MPs) in agricultural soils have become a critical environmental issue with significant implications for soil health, crop productivity, and ecosystem stability. This study delves into the multifaceted impacts of MPs, particularly in terms of soil fertility and nutrient recycling within agricultural settings. MPs, defined as particles less than 5 mm in size, originate from varied sources, including agricultural practices, product residues, and atmospheric deposition. They disrupt soil structure, alter microbial communities, and interfere with the nutrient cycles essential for plant growth. Microplastics also serve as carriers for pollutants that further degrade soil quality and pose risks to food security and human health. The research employs quantitative analyses to establish a correlation between microplastic concentration and its effects on soil properties such as bulk density, porosity, and nutrient absorption capabilities. It highlights the urgent need for comprehensive management strategies and regulatory frameworks to mitigate MPs’ pervasive impact on agriculture and safeguard environmental health.
