Abstract :

The present investigation was carried out in Acharya N.G Ranga Agricultural University, Rajendranagar, Hyderabad, Andhra Pradesh aimed to analyze the role of multipurpose tree systems in improving soil organic carbon and micronutrient availability. Soil samples were taken for micronutrients at three depths i.e. 0-30, 30-60 and 60-90 cm. The results revealed that under the different multipurpose tree system higher accumulation of organic carbon was observed in Pongamia pinnata (0.57 to 0.29%) and lower in fallow land (0.09 to 0.08%) at different depths. Among the different micronutrients, Acacia nilotica tree system recorded the higher zinc, iron and cupper content were 1.32, 5.84 and 1.67 mg kg-1 respectively.
