Land Drainage

Definition: Land Drainage

Land Drainage: Land drainage is the process of removing surplus water from land. If surplus water is prevented from moving through the soil and subsoil, it soon fills all the pore spaces in the soil and this will kill or stunt the growing crops. Well-drained land is better aerated, and crops are less likely to be damaged by root-destroying fungi. Aerated soil also warms up more quickly in spring. Plants form deeper and more extensive root systems, grassland is firmer, and disease risk from parasites is reduced. The main methods of draining land are underground pipe drains, mole drains, and ditches. Proper land drainage improves soil health and crop yields.
