What is the role of cover cropping and conservation tillage in improving soil structure, water infiltration, and resilience to erosion while enhancing the quality of produce in cereal-legume cropping systems?
Cover cropping and conservation tillage are crucial practices for enhancing soil health, improving water infiltration, and reducing erosion. Cover crops, planted between main crops or during fallow periods, increase soil organic matter, prevent erosion, and boost nutrient cycling. Conservation tillage, which minimizes soil disturbance, further contributes to soil health by increasing organic matter, improving soil structure, and enhancing water infiltration.
Incorporation of cover crop into cropping system increases (1) time of active rooting (2) protects soil from rain fall impact(3) improves soil OM quality and increases SOM quantity compared to bare soil (4) increases soil microbial activity and diversity due to increased supply of root exudates, nutrients,water and oxygen,thus improving soil health. Conservation tillage Increases soil bio-diversity, improve soil water and nutrients cycling, reduces soil degradation in terms of wind and water erosion, soil OM, nutrients acidification and soil compaction.
