Frequently Asked Questions


  1. Sound Agriculture develops nature-based solutions for tastier, healthier and more sustainable food. Our breakthrough biochemical technology enables agriculture to adapt faster to climate change and evolving consumer preferences, creating healthier food that is also better for the planet. SOURCE, our flagship product, activates the microbiome to give crops access to more of the nitrogen and phosphorus that exists in the field, improving yield and reducing synthetic fertilizer in corn by up to 50 lbs per acre.

  2. Sound was started to create new solutions to help growers face modern day challenges caused by extreme weather, supply chain disruptions, and escalating prices. Our focus is on offering new tools that help produce more food using less land and fewer resources.

  3. Sound Agriculture was founded by Eric Davidson, PhD and Travis Bayer, PhD who use their expertise in molecular biology, biochemistry and biophysics to bring science-based solutions from the lab to the field. Learn more about our leadership team.


  1. SOURCE is a microbiome activator that improves nutrient efficiency by giving plants access to more of the nitrogen and phosphorus that exists in the field. It can be used to increase yield or to reduce synthetic fertilizer application without impacting yield.

  2. SOURCE is a foliar-applied biochemistry that is tank mix compatible with herbicides or fungicides. The optimal timing of SOURCE products varies by crop. For SOURCE Corn, we recommend V4-V6 or VT-R3. For SOURCE SC applied on soybeans, we recommend V4-R3 application.

  3. When SOURCE is applied as a foliar spray, plants absorb the product and send the active ingredient through the roots into the soil. The product mimics a natural signal sent by plants to microbes, nitrogen fixation and phosphate solubilization to provide more nutrition to the plant.

  4. SOURCE provides access to more nutrients during the season, allowing it to be used to boost yield or replace nitrogen inputs. With SOURCE Corn, growers get an average 5-10 bushel increase, or when combined with nitrogen reduction (25-50 lbs/acres), growers are able to maintain yield. With SOURCE SC, growers see an average 1-3 bushel increase in soybeans. Additionally, the in season nutrients provided by SOURCE lead to many other benefits, including healthier plants, larger stalk diameter, greater root mass and increased ear size.

  5. There are currently three products within the SOURCE portfolio. SOURCE Corn for use on Corn, SOURCE SC for use on soybeans, and SOURCE DC for use on cotton, wheat, alfalfa and grass hay.
