The soil organic matter increased with the increasing altitude because of slower decomposition rate with increasing altitude. This can again be owed to increasing trend of soil organic matter with increasing altitudinal range. 0-20 cm may be explained in the sense that there is continuous accumulation of leaf litter on the surface, which keeps on decomposing and thus enriches the upper layer (0-20 cm) continuously. Rheum australe is one of the important high value species, which has huge economic potential, being used in pharmaceutical industries and due to heavy anthropogenic pressure its natural population is threatened, which in turn has affected the natural regeneration. The higher amount of soil organic carbon stock on the surface layer i.e. There is an urgent need to develop regeneration/conservation strategies for over exploited medicinal and aromatic plant species. Indian Gerontological Association (Registration No 212/1968) is an independent ... This may be because of enhanced accumulation of leaf litter in the tree and fruit based land use systems. P.)

In the altitudinal range, soil organic carbon stock increased with increasing altitudinal ranges from 1100-2300 m, however, altitudinal range of 1700-2000 masl remained statistically at par with 2000-2300 m above sea level. Soil Science Society of America, Madison, Wisconsin. Soil quality under forest compared to other landuses in acid soil of North Western Himalaya, India. Sharma V, Shabeer Hussain, Sharma KR and Arya VM 2014. Carbon and nitrogen storage in agroforests, tree plantation and pastures in western Oregon, USA. The Himalaya covers 18% of the Indian sub continent, accounts for more than 50% of Indian forest and contains 405 of India's endemic species (Maikhuri et al., 2000). Soil carbon content declined significantly from upper (0-15 cm) to lower soil layer (15-30cm). decrease in organic carbon content with increase in soil depth have also been reported by Chauhan et al. Maximum soil organic carbon stock (SOC stock) was recorded in forest land use system (49.04 t ha-1), which was followed by agri - horticultural (20.59 t ha-1), horticulture (20.52 t ha-1), silvi-pastural (17.90 t ha-1) and agricultural system (16.94 t ha-1), in the descending order. Soil carbon inventory (t ha-1) under different land use systems along an altitudinal gradient in the mountain ecosystem of Kullu district (H. Effect of different species on soil properties under agroforestry system. It has been pointed out that nearly 60,000 plant species may be in danger of extinction leading to gene erosion during the next 30-40 years. Internet is the biggest medical library in the world. Search engines are used by almost 81% of the e-patients to look for the information ... Thirteen Colonies were established in America, which were governed by England itself. This may be due to the nature/composition of the forest. Seeds were collected from natural ecological zones of Rheum australe during October month from different parts of Himachal Pradesh.
