Kansas Agricultural Experiment Station Research Reports
Grain sorghum production in alkaline or calcareous soils is frequently affected by iron (Fe) chlorosis. Soil conditions such as high pH, high free calcium carbonate (lime), and low organic matter favor development of iron deficiency chlorosis (IDC), which can delay crop maturity and reduce yields. Two field experiments were conducted in the summer of 2014 to determine the effectiveness of Fe chelate application in alleviating IDC in grain sorghum. Treatments in the first study were four Fe chelate application rates (0, 3, 6, and 9 lb/a) applied either in-furrow with the seed at the time of planting or 2 weeks …
