Activating the soil



Soil holds the innate ability to provide for the plant. Every season, extra bushels are left in the field because current tools are unable to access the soil’s full potential. Source solves that issue by unlocking the nutrients already found in the soil. When science and modern innovation take hold, it leads to a more environmentally sound solution for better production and more efficiency. It’s not magic, just science.

Source was developed based on a deep understanding of how the plant and environment interact. Applied as a foliar spray, Source signals the existing soil microbes to turn on atmospheric nitrogen fixation and phosphate solubilization to increase nutrient availability when and where the plant needs it most. See it in action.
