In a demonstration conducted by Nutrien Ag Solutions in Galesburg, Illinois, Extract PBA was sprayed in fall on a corn field post-harvest. In the following spring, stalks were pulled and split to examine the differences in residue breakdown between treated and untreated parts of the field.
As seen in the photo, the Extract-treated stalks were in a more advanced stage of decomposition than untreated stalks by early spring.
Extract PBA was sprayed on Nov. 29, 2017. This photo shows corn stalks from treated and untreated parts of the field that were pulled and split on March 23, 2018.
