Conditions of Application and Efficiency of Biodrainage

Abstract

Biological drainage (forest planting, perennial grasses (Lucerne and others) with deep root system (2-4 m and above), main crops (e.g. wheat, cotton plant and others) embrace leakage and ground waters and utilize them for transpiration. Due to this the level of ground water comes down, ground water rise and salt build-up in active layer are reduced. Biodrainage, as against artificial drainage and antifiltration measures, requires low capital investments, softens microclimate, protects crops seeds from harmful effect of dry winds, reduces evaporation from water surface and lowers wind speed over the surface of soil.
