Abstract

Carbon has become crucial from view point of atmosphere as well aslithosphere. The largest exchange of carbon take place betweenatmosphere and the vegetation, since about half the carbon fixed byplants is respired back and the net primary production is only about 60Pg C/ha /year. The global pool of carbon is described in the followingfigures. In soil although soil carbon is not directly related to the plantnutrition yet the plant nutrition is governed by the C status of soil. Itplays pivotal roles in several processes of the soil ecosystem includingnutrient cycling, soil structure, formation, C-sequestration, waterretention detoxification of anthropogenic chemicals and energy supplyto soil microorganisms. The nature, content composition and behaviour of organic matterin soil are fundamentally important for growth of crops under diverse climat iccondit ions. The organic matter applied to soil is subjected to decompositiondepending on the soil and environmental conditions. The experiment was laid out in arandomized Block Design. As regards to the treatments three levels each of Chinar, Juglens, Morus,poplar and Salix leaves were employed in C5, C10 and C20; J5, J10 and J20; M5, M10 andM20; and P5, P10 and P20 and S5,S10 and S20 respectively. The total number of combinations worked out to 16 increasing control. The crop was harvested on 28-10-2015. The crop stands very good. The stems were thick and the plants grew to a height of over 86.80cm.
