Abstract

Study was carried out at Spituk village of Leh District for assessing the biomass carbon stock and rhizospheric properties of a dioecious shrub-Hippophae rhamnoides (Seabuckthorn). Biomass and carbon stock was assessed using the destructive harvest method in 3 quadrat plots of 10 x 10 m each in this study. Soil samples were collected in the quadrat plots from soil underneath Seabuckthorn. It revealed that the stand level total biomass of shrubs attained 30.78 mg ha-1 at diameter class of 6.1-7.0 cm and total stand level vegetation carbon stock also tracked a similar trend to biomass. The total carbon stock in vegetation+soil at stand level was 74.15±8.58 Mg C ha-1. While stand level total nitrogen was 9.80 Mg ha-1 at shallow depth i.e. from 0 to 0.3 m and declines (4.89 Mg ha-1) in the depth range of 0.3-0.6 m. Soil reaction near the shrub indicated alkaline range of pH (8.71±0.24) throughout depth range of (0-0.9 m) with electrical conductivity in the upper top layer (0-0.3 m) higher as compared to deeper zone (0.3-0.9 m). It is concluded that Hippophae should be considered as potential shrub for carbon stock development reserve and soil improvement in Ladakh. Key words: Seabuckthorn, cold desert Ladakh, biomass, carbon stock, nitrogen
