Agricultural drainage patterns describe how water moves through the soil and sub‑soil layers in croplands, influencing field capacity, root zone moisture, and crop yield. Mastering the classification of patterns, the driving forces (gravity, capillarity, pressure), and the impact of field layout and soil texture is essential for exam questions on design and management of drainage systems.
