Biochar is used as a solid amendment to stabilize the soil nutrients in otherwise nutrient - deficient soils. In the present study, the mobility of soil phosphorous and phosphomoonoestrases were monitored with respect to biochar amendment. Biochar amendment was used at different application rates with soil and soi sludge mixtures. Soil samples collected at different time intervals were evaluated for phosphorus levels and (acidic and alkaline) phosphatases enzyme activities. The entire data set was subjected to kinetic modeling and results showed that the data was best described by parabolic diffusion in the available and total phosphorus. Acidic and alkaline phosphatase activities follow the rate equation of power function. Briefly, our study suggests that the biochar addition alter the initial adsorption rate, diffusion of available phosphorus and total phosphorus. The biochar acts as sustainable source of phosphorus and also sustain the available phosphorus in soil and sludge.
