Impact of crop residue recycling and chemical fertilizers on soil health and nutrients uptake under different cropping systems – a scopus review

Abstract

Technology developed for sustainable agricultural practices have gained considerable attention in recent years due to their potential to enhance soil quality, increase crop productivity and mitigate environmental challenges. Integration of crop residue recycling and judicious use of chemical fertilizers, which collectively influence the buildup of organic matter, improvements in physical and chemical soil properties and nutrient uptake by plants. Crop residue recycling played a crucial role in bolstering organic matter content. Chemical fertilizers supplement essential nutrients that may be deficient in the soil, stimulating plant growth and development. The interaction between crop residues and chemical fertilizers is complex and dynamic. These improvements facilitate root penetration, leading to enhanced nutrient and water uptake by plants. Moreover, crop residues retention reduces soil erosion by promoting surface cover, which helps maintain soil structure and prevent nutrient loss. The build-up of organic matter in soil improved the soil chemical properties, nutrients status and their transformation. Additionally, organic matter enhances soil buffering capacity, mitigating pH fluctuations that can affect nutrient availability. The joint application of crop residues and chemical fertilizers can foster balanced nutrient management, reducing the risk of nutrient imbalances or toxicities. Nutrient uptake by plants is profoundly impacted by these practices. The integrated nutrient management through combination of crop residues and chemical fertilizers enhances nutrient availability, leading to improved nutrient acquisition by plants. This review resulted into the increased crop yield and quality, contributing to food security and economic sustainability.
