Methods of replenishing plant nutrients in the soil - SS2 Agriculture Past Questions and Answers - page 2

Crop rotation is a farming practice where different crops are planted in a specific sequence on the same land over time. It helps maintain soil fertility by preventing the depletion of specific nutrients and disrupting the life cycles of pests and diseases.

Organic manure is beneficial in agriculture because it improves soil structure, adds organic matter, and enhances microbial activity. It differs from synthetic fertilizers because it releases nutrients gradually and supports long-term soil health.

Liming involves adding lime, usually calcium carbonate, to soil. It raises soil pH, making acidic soils more suitable for plant growth. It also improves nutrient availability by reducing soil acidity.

Fallowing is the practice of leaving land uncultivated for a season or more. It contributes to soil nutrient replenishment by allowing the soil to naturally recover and replenish nutrients. It's typically done when soil health needs restoration.

Cover cropping benefits agriculture and the environment by protecting the soil from erosion, suppressing weeds, and adding organic matter. It also enriches the soil by fixing nitrogen and supporting biodiversity, making it a sustainable farming practice.
