How can Extract PBA help me deal with my post-harvest crop residue?

Many growers turn to fall tillage or a fall nitrogen application to help them speed residue breakdown. Although tillage does a good job of physically breaking up the residue and increasing the surface area that microbes have to work on, it has little direct influence on the mineralization of nutrients trapped in residue. Nitrogen can provide some benefits, but the main limiting factor for residue breakdown is not lack of sufficient nitrogen, but rather low soil temperatures. Microbial activity, which is what produces the biochemistry needed to break down crop residue, drastically drops off below 50 degrees F. This is why we recommend a post-harvest application of Extract PBA—which contains biochemistry that isn't as impeded by low soil temperatures as live microbes are—to help speed residue breakdown and help crops access the nutrients in crop stubble.
