| Abstract/Contents: | "Iron (Fe) is a common component of granular fertilizers applied to horticultural and agricultural crops. Chelating agents are required to maintain Fe solubility and increase plant uptake. Numerous products are marketed as Fe chelates but few have been confirmed to increase Fe solubility in soils. The objective of this study was to determine the solubility of Fe from ten common Fe fertilizers applied to eleven North American soils. Brookston, Cecil, Fuquay, Hallandale, Marietta, Marvyn, Nunn, Pinavetes, Stephenville, Troup, and Zook soils were incubated with soluble Fe applied as sulfate, glucoheptonate, polysaccharide, humate, oxide, citrate, IDHA, EDTA, DTPA, or EDDHA. At 1 h, 1 d, 1 wk, 2 wks, and 3 wks, soils were extracted with 0.01 mol L-1 CaCl2 and analyzed for Fe. In each soil 1 h after application, greater than 95% of applied Fe was rendered insoluble from sulfate, glucoheptonate, polysaccharide, humate, and oxide. The chelates FeEDTA, FeDTPA, and FeEDDHA increased Fe solubility for 3 wks in most soils with solubility ranging from 5 to 40% of applied Fe. The natural organic chelate, FeIDHA, increased Fe solubility in most soils for 1 d, but soluble Fe from FeIDHA declined to untreated soil levels thereafter. Soil-applied Fe fertilizers should be limited to EDTA, DTPA, or EDDHA." |
