Agri sc testimonial IN Musselman

"I first used Agri-SC® based upon a recommendation. I was looking to fight compaction and improve drainage. I notice an improvement in seed to soil contact and definitely in any tillage, a lot less clods. I broadcast spray Agri-SC® and like applying with a fall application. I have also used it in furrow with insecticide for corn."

"Agri-SC® stops the ponding in fields and lets the ground get mellow. In the spring, we can get onto the fields earlier. We have wet Clermont, tight ground, and Agri-SC® lets us farm this at a normal early time. We have been no-tilling since 1985, and Agri-SC® and no-till go together good. We have been using it since the mid 80's. We use it in spring with burn down and have never had any problem mixing with any herbicides. Try it a couple of years and you will see the difference."

"I no till most of my ground. The way to eliminate some of the compaction is to use Agri-SC®. It sure helps eliminate compaction and provides the ability for roots to move through the soil. I apply 6 oz. of Agri-SC® with my first chemical application trip. I see the results with better yields, less compaction, and less standing water in the wheel tracks. I've probably been using Agri-SC® 20 plus years."
