Soil variations in relation to Forest Management in Lalsohanra irrigated plantation
Jalal-ud-Din and M. Farooq
ABSTRACT
The soils of the Lalsohanra irrigated plantation are of various kinds with different problems. Main kinds of soils and their problems have been identified and described. Some reclamation measures have been suggested. The soils are dominantly loamy and are homogenized. At places they are clayey and stratified. These soils occur in the valleys locally known as 'dhars'. About 50 per cent of the area is occupied by sand dunes having irregular relief. Salinity and sodicity, dense soil mass and sandy natures are the main soil problems that adversely affect the suitability of the area for shisham and other tree species under irrigation. Under the existing conditions of arid climate and shortage of irrigation water the problematic soils could better be used for original flora or drought/salt resistant tree species. If, however, sufficient water is made available for intensive forestry, the reclamation of saline-sodic soils could be
undertaken by using gypsum and growing high delta crops. The dense soil mass could be improved by subsoiling and green manuring. The sand dunes cannot be brought under irrigated plantation. They could be developed as range land, or used for wild life.
