Soil Conservation Hedges
Trees can be planted on physical soil conservation works (grass strips, bunds, risers and terraces), wherein they play two roles to stabilize the structure and to make productive use of the land they occupy. Stabilization is through the root system. In some of steeply sloping landscapes of the country, the risers or terraces are densely planted with trees, with multiple uses being made of them for fruit, fodder and fuel wood. In this system the major groups of components are multipurpose and/or fruit trees and common agricultural species. The primary role of multipurpose/ fruit trees and agricultural species is soil conservation and provision of various tree products. In this system the agricultural crop like food grains, pulses and vegetables are taken as intercrop in the forest trees like Shirish, Sal Teak wood, Eucalyptus, Austalian babhul, Bakan, Anjan, etc. The forest trees are planted in rows of 15-20 m. In lines of forest trees, agricultural crop, grain crop are cultivated as intercrops.
