Abstract

The effects of filter cake on phphate status in a submerged acid sulfate soil (Rangsit Soil) were studies. In addition, effects of filter cake on pH and reduction state of acid sulfate soil were also included. Rangsit soil was amended with filter cake or KH2PO4 or KH2PO4 + CaCO3 in the rate of 0 and 2.868 mg P/10 g of dried soil and 0, 9.5 mg Ca/10g of dried soil. Filter cake increased the amount of available P in the submerged acid sulfate soil (Rangsit Soil). The effectiveness of filter cake in increasing available P in acid sulfate soil. Furthermore the ability of filter cake in increasing pH of acid sulfate soil was similar to that of CaCO3. Filter cake did not enhance reduction state of submerged acid sulfate soil.
