Studies on Physico Chemical properties and Available Nutrients under Paddy Land Use Cover of Thirthahalli Taluk, Shimoga District

摘要

Soil quality mainly depends on the response of soil to different land use systems and management practices, which may often modify the soil properties and hence the soil productivity, chemical properties viz., soil organic carbon content and cation exchange capacity have been reported to be comparatively low in the soils under grasslandthan under cultivated land system. Effect of land use systems on soil properties provides an opportunity to evaluate sustainability of land use system and thus, the basic process of soil degradation in relation to land use and hence, the soil and crop management must be given high research priority (Woldeamalk et ah, 2003). However, the information on effect of paddy land use cover system on soil quality to give recommendations for optimal and sustainable utilization of land resources scanty. The present investigation was taken up to know the chemical characteristics of soils under paddy land use cover.
