Correct Answer: Option B
Explanation
Crop rotation is the practice of growing different crops in sequential seasons on the same land. Ecological benefits: (1) Nitrogen replenishment — legumes (soybean, pea, clover) fix atmosphericvia rhizobial symbiosis, replenishing soil nitrogen naturally; (2) Pest/pathogen cycle disruption — breaking monoculture eliminates host-specific pathogens and pests; (3) Soil structure improvement — different root architectures improve aeration and water retention; (4) Weed suppression — varied crops prevent adaptation of weeds. Repeated use of fertilisers causes soil salinisation, pH imbalance, and microbiome disruption. Growing the same crop depletes specific nutrients and builds up crop-specific pests. Burning crop waste destroys organic matter and releases.
