Characterization of Fertility Status and Soil Acidity of the Experimental Farm of Sasrd, Nagaland in Relation to Land Uses

摘要

The effect of land use on soil fertility and soil acidity status were studied from five land uses, viz., Banana Orchard, Bench Terrace, Contour Terrace, Forest North-facing and Forest South-facing of experimental farm of during 2014-2015. The soils ofthe study area were acidic in reaction, varied from 4.33 to 5.00, high in organic carbon and low to medium in cation exchange capacity. Maximum available N and P recorded in Forest North-facing whereas, K was in Forest South-facing. Maximum available Al, Exchangeable Al, and exchangeable acidity were found in Contour Terrace, whereas, total acidity and pH dependent acidity were found in Forest North-facing. Organic C content exhibited significant positive correlation with available N, available P and pH dependent acidity.
