An experiment was conducted during 2019-20 at Forest College and Research Institute, Mettupalayam, to assess the effect of the different agroforestry practices on soil physico-chemical and soil microbial activity. The block plantation tree species comprises viz., Khaya senegalensis, Melia dubia, Dalbergia sissoo, Populus deltoides, Casuarina equositifolia and Control (Open area) with four different intercrops viz., greengram, cowpea, blackgram, gardenpea. The soil was analysed for soil pH, soil electrical conductivity, organic carbon, available, nitrogen, available phosphorous and potassium as compared to control. The intercrops showed a decreasing trend in soil pH. EC, soil organic carbon, available soil nitrogen, available soil phosphorus, and available soil potassium and microbial populations are increasing trends. Melia dubia + blackgram combination (T9) land uses have significantly higher soil fertility status and microbial operations among tree crop combinations under investigation. Khaya senegalensis trees alone had the lowest EC, soil organic carbon, available soil nitrogen, available soil phosphorus and available soil potassium (T1).
