Brief Project Summary:

Iron deficiency chlorosis (IDC) is a common yield-limiting factor for soybean produced in North Central Region. Yield losses have been estimated to cost regional producers at least $120 million annually. The scope of the problem has grown as soybean production has expanded throughout the high pH regions of western Minnesota and the Dakotas.

Although iron is an abundant plant nutrient in soils, iron deficiencies are common in alkaline soils. The solubility (availability) of iron is reduced as the pH of the soil is increased. Fe(3+) ions are soluble at pH lower than 3 and Fe(2+) ions are soluble at pH 4-6 and iron solubility is decreased to a minimum in soils with a pH of 7.5-8.5. ...

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
