Concept of irrigation and drainage

Irrigation and drainage are the two sides of the water‑balance equation that governs crop productivity and soil health. Irrigation supplies water to compensate for evapotranspiration and rainfall deficits, while drainage removes excess water and prevents waterlogging and salinisation.
