Spatial soil status of exchangeable Ca, Mg and Na under different land use systems of district Doda, J&K

Abstract

To assess the spatial exchangeable nutrient status (Ca, Mg and Na), a soil survey was conducted at district Doda, J&K. Composite surface soil samples were collected randomly from different land use systems viz; Forest, Horticulture at a depth of (1 metre), Barren Lands and Agriculture at a depth of (0-15cm). The exchangeable calcium recorded was higher under barren lands (2.15-6.18 meq100g-1) followed by horticulture, forest and agriculture land uses. The exchangeable Magnesium of the soils under different land use systems recorded was higher under barren lands (0.57-1.75 meq100g-1) followed by horticulture, forest and agriculture land uses. The exchangeable sodium range recorded was higher under barren lands (15.69-97.56 mg Kg-1) followed by forest, horticulture and agriculture, respectively. Exchangeable calcium was low (
