Abstract
Abstract A series of inorganic and chelated ferric and ferrous fertilizers were tested for their ability to alleviate Fe chlorosis as foliar and soil application on peach and grape under field conditions. Limited re‐greening was obtained with foliar application of ferric citrate/ammonium nitrate, ferrous sulfate and DTPA on peaches, and with foliar application of ferric citrate/ammonium nitrate and ferrous sulfate and soil application of ferric citrate/ammonium sulfate and ferric citrate/urea/ammonium nitrate on grapes. The only treatments that resulted in complete elimination of iron deficiency, as indicated by complete re‐greening and plant rating, was soil application of EDDHA on both peach and grape. Soil application of methyl‐EDDHA was almost as effective as EDDHA, resulting in slightly less intense re‐greening and chlorophyll content.
