Abstract
The present study highlights the impact of resource conservation techniques on soil properties in sub montane north western Himalayas. The continued maintenance of fertile soil is essential in order to meet basic human needs. The topography of the region ranging from gently sloping to moderately-steep sloping retards the vertical development of soils. The study was conducted in the Merth village of state J&K. The experiment was laid out to compare the impact of resource conservation techniques on the runoff and sediment yield in two different catchment areas (one with sandy loam texture and other with clay loam texture) in monsoon season. The slope of the catchment areas varies from 3-6%. The increase in available nitrogen in sandy and clay loam can be attributed because of the increase in root biomass under resource conservation techniques. Addition of root biomass and litter fall in cover crop indirectly through the process of mineralization increases the availability of available nitrogen. The soils of submontane Shivaliks are under tremendous stress because of high soil erosivity and poor soil management practices. The study strongly recommends adoption of resource conservation techniques for reducing soil erosion & water conservation in submontane Shivaliks.
