Macronutrients distribution in submontnae soils of the Jammu in relation to soil properties
Author(s): Vijay Kumar and KR Sharma
Abstract: Submontane soils are alluvium deposited in the valley floor by the Jhelum and the Indus Rivers of the Jammu are prone to deficiency of macronutrients. Four profiles from forest, horticulture, agriculture, pasture and degraded lands in the submontane tract Jammu were investigated for available N, P, K and S. The available macronutrients varied from 27.44-128.24 for N, 2.94-18.24 for P, 28.93-70.88 for K and 0.19-5.75 mg kg-1 for S. The available macronutrients were superior in fine textured soil than in coarse-textured soils. Soil texture was dominant in sandy loam than sandy clay loam with variation in relation to topography. Organic carbon, pH, clay and silt content exerted strong influence on the distribution of macronutrients. The available macronutrients N, P, K and S increased with increasing organic carbon content but decreased with increase in pH. The available macronutrients content increase in clay and silt contents and reduced with increase in sand content. The results revealed that the nutrients declines as land use changed from forest to pasture and cultivated lands. Hence, it is potential to assume that continuous and intensive cultivation reduces plant nutrients critically which need to take actions for maintaining its macro-nutrients status for the horticulture and Agriculture soils in the study areas.
