soil management

Soil management is crucial for agriculture, focusing on preparing the soil for planting (tilling) and adding nutrients (fertilizing). Soil fertility is its ability to provide essential compounds for plant growth. When fertility is low, fertilizers or natural materials like farm manure can be added to supply nutrients.12

Practices like green manuring, where crops are grown and plowed under, can improve soil quality by adding nitrogen and organic matter. Farm manure is a valuable organic fertilizer, vital for organic farms, providing nutrients and improving soil structure. However, unsustainable practices like aggressive tilling and lack of cover crops can lead to soil erosion and degradation, threatening arable land. Techniques such as minimum tillage, cover cropping, and mulching are employed to conserve soil and prevent erosion. Desertification, the decline in biological productivity of drylands, is exacerbated by climate change and unsustainable land management, posing a significant global challenge.123456
