Crop rotation involves growing different crops alternately on the same field. Its benefits include: 1) Soil fertility improvement: Leguminous crops (like pulses) fix atmospheric nitrogen, enriching the soil. 2) Pest and disease control: Breaking the life cycle of specific pests and pathogens associated with a single crop. 3) Weed suppression: Different crops have varying growth habits that can outcompete certain weeds. 4) Reduced reliance on synthetic fertilizers: By naturally replenishing nutrients. It contributes to sustainable agriculture by minimizing the need for chemical inputs, preserving soil health, enhancing biodiversity, and ensuring long-term productivity without degrading the environment.
