Abstract
Abstract High soil sorption of phosphorus (P) in some P deficient low pH soils reduces the efficiency of P fertilizer use and crop yields. Silicon (Si) application has been reported to decrease P sorption and increase yields in such soils. The effect of silicate on P sorption and availability and on growth of maize (Zea mays L. cv. Golden Acres 7885) grown in a low pH Greenville soil from the Coastal Plain of Georgia was investigated in laboratory and pot experiments. Applied sodium (Na) silicate markedly reduced the soil's high P sorption. In a pot study in a greenhouse, both maize shoot and root dry weights were increased by applications of silicate, phosphate, and by applications of silicate together with phosphate. Dry weights of both shoot and root were increased by 3.92 mg Si/pot when Si was applied together with P. Silicon and P contents in the shoot and the root were increased by Si, but not by P application. The reduced P sorption when silicate was applied was adduced to the increase in the soil ...
