Effect of fulvic acid on the phosphorus availability in acid soil

The incubation experiment was conducted to evaluate the influence of fulvic acid (FA) on phosphorus (P) movement and transformation in acid soil. FA at the rate of 0, 0.1, 0.2, 0.3 g and in combination with 0.19 g KH2PO4 was sprinkled uniformly on the surface of the filter paper on the soil cylinder...
