Abstract:
The study was carried out at 30 years old plantation of tree species which followed with cropping system viz. Casuarina + Guava + Turmeric, Casuarina + Paddy + Wheat, Shisham, Shisham + Peragrass, Shisham + Mustard, Shisham + Paddy + Wheat and Eucalyptus). The influence of cropping system and plantation of tree species was evaluated the fertility level of soil at 0-15 cm depth. The samples were analyzed which resulted that the accumulation of available nutrients and microbial counts were higher under plantation of trees than control. The available macronutrient (Nitrogen, Phosphorus and Potassium), micronutrient (Zinc, Iron, Copper and manganese) and Microbial count (Bacteria, Fungi and Actinomycetes) were higher under Casuarina + Guava + Turmeric in surface layer) than other tree species. Therefore, the tree plantations and cropping system improved the nutrient availability and microbial counts in the soil.
