Abstract: A laboratory experiment conducted to study dynamics of phosphorus in soil under different organic amendment treatments. Soil treated with FYM @ 20 t ha-1, vermicompost @ 20 t ha-1, poultry manure @ 20 t ha-1 and paddy straw @ 20 t ha-1 respectively with incubated up to 60 days. Different soil properties pH, EC, organic carbon, available phosphorus and different fractions of phosphorus were analysed. All organic amendments application increases the Olsen’s P in comparison to no application of organic amendments respectively. The range of phosphorus availability was 15.90-26.28 mg kg-1 in organically amended soil during the incubation period. In general, the range of saloid-P, Al-P, Fe-P and Ca-P was observed 4.22-22.40, 8.45-32.43, 12.67-35.38 and 164.85-215.29 mg kg-1 respectively, in organically amended soil during the incubation period. Available P is significant correlated with saloid-P (r = 0.973*) at 21 days and Ca-P (r = 0.901*) at 60 days. Organic amendment showed significantly increase of soil EC (dSm-1) and organic carbon (%) but significantly decreases with soil pH. These findings may be used as guide for increasing phosphorus use efficiency and thus fertilizer recommendation.
