This book is a practical guide to managing soils and water in irrigated agriculture. It starts with the basics—how soil is built (texture, structure, density), how it can degrade, and how chemistry and soil organic matter affect fertility. It then explains the soil–water–plant links: how water is stored and moves in soil, how roots take it up, and how to schedule irrigation for healthy crops. Clear chapters walk through N, P, K, secondary nutrients and micronutrients specifically under irrigation, with tips to avoid losses and fix deficiencies. You’ll also learn how to evaluate land for irrigation, test irrigation water quality, use saline water safely (when and how), and improve efficiency with better timing, application methods, and drainage. Checklists, simple calculations, and field cues help you make sound, field-ready decisions.
