Adding trees to the cropping equation

Salinity control strategies on many farms combine tree plantations with cropping and grazing enterprises. The aim of such plantations can be to reduce recharge to groundwater tables by intercepting the vertical and horizontal flow of water in the soil profile, to make productive use of saline discharge areas, or to draw down the water table in areas where it is close to the surface. Design of agroforestry systems must take water movement and salt accumulation and water table levels into account.
