Characterization of soil resources of Patapur microwatershed for sustainable land use.

摘要

Soils of Patapur microwatershed area Manvi taluk, Raichur district, Karnataka, were studied for their properties. The soils were moderately deep to vary deep, dark reddish brown (2.5 yr 3/4) to brown (10 yr 4/3), clay loam to clay in texture. The pH ranged from 7.14 to 9.25, EC from 0.09 to 3.79 dS/m, low to medium in organic carbon (2.6-16 g/kg) and low to moderate in CEC (7.5-52.25 cmol(p+)/kg). Slicken-sides were prevalent in lowland pedon. The soils were evaluated for land capability, and soil-site suitability for crops. Land capability sub-classes in the study area were III and IV with limitations of texture, drainage, fertility and topography. Majority of the soils were moderately to marginally suitable and few were potentially unsuitable.
