Iron deficiency chlorosis (IDC) is a production challenge for farmers growing soybeans [Glycine max (L.) Merr.], especially in the Red River Valley. It is critical to correct this deficiency as soon as symptoms arise before growth, and ultimately yield, is negatively impacted. Field experiments of foliar applied iron fertilizers (o-o-EDDHA, o-o-EDDHSA, HEDTA, and an amino acid) and suitable adjuvants (HSOC [high surfactant oil concentrate], non-ionic surfactant, acidifier, and organosilicone surfactant), to control IDC were conducted during the 2013 and 2014 growing seasons, respectively. There was high variability among the results for both the SPAD meter readings and soil iron concentration. The yield values were greater in the treated plots than with control plots, but not significantly so. Further experiments should be conducted to gain more knowledge on the prolonged use and efficiency of these products in the correction of IDC.
