Effect of microbial inoculants (VAM and PSB) on soil physicochemical properties

A.Sandhya, T.Vijaya, G.Narasimha

The aim of this study is to determine the effects of microbial inoculants, (microbial fertilizers) on soil physico-chemical properties Supplementation of biofertilizers such as Vesicle Arbuscular Mycorrhizal (VAM). Fungi, and phosphate solubilizing bacteria (PSB). Supplementation of bioinoculents to soil improved the physical properties such as colour, and chemical characteristics, organic carbon, nitrogen, phosphorous, potassium, and lowered the electrical conductivity (EC)..With increasing the soil incubation time also these parameters are improved in soil treated with microbial inoculants than control. Improved physical and chemical parameters in test soil in this study is an indication of improvement of soil fertility due improved microbial and their biochemical and metabolic activities.
