Impact of organic manure amendment on soil physicochemical, biological and enzymatic properties

G.Narasimha

In this study, physico-chemical, microbial and enzymatic properties of soil composed with organic manure was studied. Soil composed with organic manure underwent changes in all measured physicochemical and microbiological parameters like higher water holding capacity, moisture content, electrical conductivity, organic content andmicrobial populations than the control soil. Nearly two fold improvements in microbial populations including both bacterial and fungal populations were observed organic manure amended soil than the control. Soil cellulase activity was improved in organic manure soil. With increasing the soil incubation period the soil cellulase activity also enhanced up to 14th day interval and thereafter declined in both control and test soil.Improved physicochemical, microbial and enzymatic parameters in organic manure amended soil are an indication of improvement of soil fertility.
