    Abstract

    The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FACM) on the changes on the soil PZC status and its impact on P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 were tested. These treatments were arranged according to Factorial Completely Random Design with three replicates. The results showed that theapplication of FA-CM for each dosages of P fertilizer correlated significantly with the status of soils PZC, pH, negative charge, P sorption and P-available. PZC has possitive correlation with pH and negative charge. Negative charge has a significantly negative correlation with P sorption, and posssitively correlation with P-available.
