MP Board · Class 9 · Science · Improvement in Food ResourcesWhat is crop rotation? Explain its main advantages in maintaining soil fertility and crop productivity.
Step-by-Step Solution
Crop rotation is the agricultural practice of growing different crops sequentially on the exact same piece of land according to a pre-planned timetable. This practice offers multiple advantages: it prevents the depletion of specific soil nutrients by alternating nutrient-demanding crops like cereals with nitrogen-fixing leguminous crops like pulses. Additionally, crop rotation effectively disrupts the lifecycle of pests, weeds, and disease-causing pathogens, reduces heavy reliance on chemical fertilizers, improves overall soil structure, and ultimately maximizes long-term crop yield.
