17 Jul Impact of Crop residue on soil fertility in perspective of rice-wheat cropping system
चावल-गेहूं की फसल प्रणाली के परिप्रेक्ष्य में मिट्टी की उर्वरता पर फसल अवशेषों का प्रभाव Crop residues (CRs) are considered a vital natural resource for conserving and sustaining soil productivity. Addition of CRs to soil is a useful tool in maintaining and increasing amounts of soil organic matter. Therefore, soils have significant capacity for C storage and to mitigate atmospheric CO2. As rice-wheat cropping system (RWCS) is one of the world’s largest agricultural production systems, covering an area of ~26 M ha spread over the Indo Gangetic Plains (IGPs) in South Asia and China. Rice and wheat are harnessing enormous soil fertility therefore, to maintain the productivity of this system, replenishment of...
