If you've been following this blog then you know we are working with the Iowa Soybean Association's On-Farm Network to place trials of SuperCal SO4 around Iowa to compare using sulfur.
In a follow up to the report from June 15th, Corn Showing Signs of Sulfur Deficincy, this plot along with two others near Waverly, IA are still showing a visual response to SuperCal SO4. The first field is 3-4 leaves ahead of the check, with plants aready tasseling and silking. The check rows are 3-4' shorter, and ears have not started shooting off the stalk yet.
Please enoy these pictures and we'll update you further once ISA has released the final data.
