Amelioration of tannery effluent polluted soil and its response of black gram

In this study, a higher amount of various elements get deposited in the soil and make them polluted. Since, this polluted water reduces the crop production as well as the soil properties. To measure the bioremediation of some tree species like Pongamia glabra, Polyalthia, longifolia, Hesperia populnea, Pithecolobium dulci, Mangifera indica, Moringa olefera, Tamarindus indica, Acacia nilotica, Samanea saman and Azadirachta indica were grown in the polluted soil upto 90 days. The treatment in which all the tree species are grown in one pot and it showed a remarkable reduction of pollutants. The bioremediated soil showed a better germination in black gram seeds. The polluted soil were mixed with organic amendments like vermicompost, biofertilizer (Rhizobium) and FYM to improve the soil fertility and their toxicity was tested by growing black gram in that soil. Among the amendments, the vermicompost mixed polluted soil showed good results in morphological, biochemical and yield parameters.
