摘要：The present study deals with physico-chemical analysis of soil under pine, mixed pine and broadleaved vegetation of Surinsar forest, Jammu. Soil samples were collected from surface (0 - 15 cm depth) and sub surface (15 - 30 cm depth) layer during rainy, winter and summer season and analysed for moisture content, pH, organic carbon, available nitrogen, potassium and phosphorus. Analysis of the samples revealed that moisture content was higher in surface layer then sub surface layer and decreased from broadleaved to pine vegetation. pH was acidic in nature and decreased from soil with pine vegetation to broadleaved vegetation during all seasons. Organic carbon, available nitrogen, potassium and phosphorus decreased with increasing soil depth. The concentration of nutrients, except for potassium, was higher during rainy season. The concentration of potassium was found higher during summer season.
