The effect of land use on soil physico-chemical properties were studied in four villages, viz., Nongstoin, Kynshi, Umyiap and Maweit in West Khasi Hills district, Meghalaya, under four land uses, viz., paddy, potato, forest and jhum land, in each village. The soils of the study area were acidic in reaction, high in organic carbon and low to medium in cation exchange capacity. Bulk density and particle density were lower in surface soils as compared to sub-surface soils except in some locations. The water holding capacity was greatly influenced by mechanical composition and organic matter content in soils. The mean weight diameter and per cent aggregation showed similar trend and were significantly correlated. Hydraulic conductivity under potato and jhum land uses was higher than paddy and forest land uses.Keywords

The effect of land use on soil erodibility parameters were studied in four villages, viz., Nongstoin, Kynshi, Umyiap and Maweit in West Khasi Hills district, Meghalaya, under four land uses, viz., lowland paddy, potato, forest and Jhum land, in each village. The textural class of the soils varied from silt loam to clay with dominance of clay loam texture. Dispersion ratio and erosion index were recorded to be usually higher than the threshold limits. A highly significant and negative relationship of erosion index with clay, silt + clay and highly significant and positive relationship with sand and dispersion ratio were observed. The increase in erosion index with increase in dispersion ratio indicated the susceptibility of these soils to water erosion. Proper soil and water conservation measures need to be adopted to protect the soils from further degradation.Keywords
