ABSTRACT
An investigation was carriedout at Agroforestry research farm, Nagpur, to study the potential contribution of teak (planted during 1992, 1994, 1997 and 2004) and bamboo (planted during 1992, 1994, 1997) plantations on soil fertility status. The study evaluates the soil nutrient status in agroforestry research farm which was compared with cultivable land. Soil samples were taken from different depths 0-15 cm and 15-30 cm of 8-19 year old teak, 14-19 year old bamboo plantations and farm land, respectively. Samples were analyzed for pH, OC, inorganic carbon (IOC), available N, P, K, S and exchangeable Ca and Mg. Soil pH was lower in the teak plantation planted during 1994 at a spacing of 3 x 3m followed by other plantations and higher pH was observed in cultivable land. Higher OC, IOC, available potassium, sulphur and exchangeable calcium and magnesium concentrations was observed in bamboo planted area than teak plantations and farm land. Available nitrogen and phosphorus was significantly higher in teak (1994 3X3m) followed by bamboo plantations and cultivable land.
