Sound Agriculture has launched a first-of-its-kind product to help make nitrogen and phosphorus more available. Co-founder and chief technology officer Travis Bayer says Source is a chemistry that activates the soil microbiome. “What we’ve figured out how to do is use chemistry that you can apply over-the-top as a foliar spray; it travels down into the root zone and activates or stimulates those beneficial microbes that are already down there in the soil.” There are products on the market that applies microbes, but Source is a chemistry that activates the native soil microbes that are already there. “It is easy to tank mix with a variety of products and it is a predictable kind of technology.”
