Key words: Soil organic carbon, altitude, aspect, Bagrot valley.

Abstract

Soil organic carbon (SOC) stock in mountain ecosystems is highly heterogeneous because of differences in soil parent material, climate, vegetation and topography. The area is unexplored with respect to distribution of SOC stock. Furthermore, SOC distribution factors like altitude, slope aspect, vegetation, Continue reading Altitudinal distribution of soil organic carbon stock and its relation to aspect and vegetation in the mountainous forest of Bagrot Valley, North Karakoram, Gilgit-Baltistan – JBES
