This study was carried out in agroforestry systems of Eucalyptus tereticornis (clonal) on a sandy loam soil at Salimpur (30° 10'N, 76° 55'E; 268 m msl) in northern India which are characterized by tree density of 567 to 630 trees/ha. The aim of thisstudy was to analyze plant biomass, productivity and the storage of carbon in the plant-soil system. The climate of the study area is tropical monsoonal and semi-arid and characterized by hot summers and cold winters. The basal area of 4 to 6-year old trees under agroforestry was 8.28 to 14.98 m~2/ha. The wheat crop was grown in the interspaces between the rows of planted trees in 4 to 6-year old agroforestry systems during November to April. The soil organic carbon in the agroforestry systems varied from 0.56 to 0.02% (4-year) and 0.63 to 0.03% (6-year) in 0-100 cm soil depths; there were depth dependent variations in soil organic carbon and inorganic carbon. The plant biomass production increased with increase in age of trees in the agroforestry from 4 to 6 years. The biomass accumulation varied from 61.911 to 89.388 Mg dry matter/ha in the tree layer. The total carbon pool in the agroforestry systems was 27.259 to 39.322 Mg C/ha; total flux of carbon in net primary productivity being 8.1 Mg C/ha/year in the tree layer. The soil organic carbon pool was 22.96 to 26.30 Mg C/ha.
