摘要：
Research was conducted to determine the influence of hydroponically grown clover (Trifolium repens L.) residue pretreatment in reducing orthophosphate sorption on a fine-loamy, siliceous, thermic Typic Paleudult (Orangeburg Series) that had been coated with synthetically prepared amorphous Fe(OH)3. Results suggest that organic acids from clover decomposition bind to Fe(OH)3 surfaces and are able to complex Lewis acid cations to increase P availability. -from Authors
