A field study was conducted to study the soil dynamics in teak and bamboo stands planted to rehabilitate degraded soil in Futala farm, Dr. P.D. Krishi Vidhyapeeth, College of Agriculture, Nagpur, India. Soil samples were collected from a planting arrangement and age sequence of 0-, 8-, 14-, 17- and 19- year old plantations to assess the effects of trees stand on physic-chemical and micronutrient status of the soil. The tree stand altered the status of soil organic carbon (OC), Inorganic carbon (IOC), DTPA-Zn, Fe, Cu and Mn, decreased pH of the soil when referred to the cultivable land. The increment of micronutrients and decrement of pH in the soil was in the order of chrono-sequence and the nutrient index (NIV) for soil of teak and bamboo plantations was medium for iron, zinc and high for manganese and copper. These changes in the soil are hypothetical in agroforestion of degraded sites.
