Manure enhances soil texture, water retention, and nutrient levels. Crop rotation, growing different crops alternately, helps replenish soil nutrients, as seen in traditional practices like growing legumes and wheat alternately.

Chapter 1 Crop Production and Management
Manure and crop rotation are effective practices for soil improvement. Manure, rich in organic matter and nutrients, enhances soil structure, water retention, and microbial activity. Its gradual decomposition releases nutrients, promoting plant growth and improving overall soil fertility. Crop rotation involves alternating crops in a specific sequence, preventing soil nutrient depletion and reducing pest and disease pressure. Different crops have varied nutrient requirements, contributing to a balanced nutrient profile in the soil. Together, manure and crop rotation foster sustainable agriculture, maintaining soil health, preventing degradation, and ensuring long-term productivity.
