Breaking Down Corn Stalk Residue with Extract PBA

Posted by Agricen

In a demonstration conducted by Crop Production Services (CPS) in Galesburg, Illinois, Extract PBA was sprayed in fall 2017 on a corn field post-harvest. In spring of 2018, 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.

"I think this picture speaks volumes about product performance due to the fact that Extract PBA was sprayed when nozzles were almost freezing up, and the stalks were pulled when it was nearly freezing outside," says Michael Bern, the CPS crop consultant who performed the demo. "It's a good illustration of how Extract works when the soil microbes technically haven’t even woken up from hibernation."

Extract PBA can be broadcast or applied though fertigation at 1 to 2 gallons/acre, with 1 gallon of UAN/acre recommended and a minimum spray volume of 10 gallons/acre. Learn more by downloading the Extract PBA product booklet.
