While many reports claim the corn crop is in excellent condition, if our trials and phone calls are any indication, much of the crop is short on sulfur.
We have partnered with ISA this year and have close to 70 trials out. In this trial near Waterloo, you can clearly see the difference is color from the treated vs. non treated replications.
So what can be done if you have sulfur deficiency?
If you are going to side dress with liquid nitrogen you could add liquid thiosulfate to you N, but there are rumors that this product is in short supply.
You can spread SuperCal SO4 broadcast over your corn, with a dry spreader or with a plane. It will not burn the crop and will restore the green color in approximately 10 days.
