A new approach to nutrient efficiency


Get more out of every acre

Nitrogen and phosphorus are crucial to a healthy crop, but growers today are losing too much fertilizer to the air and water. We’ve discovered a more efficient way to help the microbes in your soil work harder — resulting in higher yields and a better return on investment than anything else in nutrient efficiency.

  • The plants treated with SOURCE were greener with improved plant health. I saw a 20 bu/​acre yield bump.

  • SOURCE is helping me make better use of the nutrients already in my field.

  • I did a tissue sample and saw a 23 percent increase in nitrogen and 69 percent increase in phosphorus.

Outperform with SOURCE

SOURCE works differently.

With chemistry at its core, it leads to more consistent outcomes by stimulating the existing microbes already in your soil.

SOURCE provides access to two critical nutrients: nitrogen and phosphorus. Your plants will notice the difference, and so will you.

Finally, a way to get more out of your soil.

  • Increased Yield

Made for growers. Simple to use.

  • Add to your tank with herbicides and fungicides.

  • < 1 ounce per acre.

  • Choose the best time to apply from V4 — R3.

Backed by science

SOURCE activates microbes in the root zone that fix atmospheric nitrogen and unlock phosphorus in the soil.

When crops are able to take in these nutrients, the outcome is healthier plants and improved yields.

Because SOURCE gives crops more access to nitrogen and phosphorus, growers see the effects of increased nutrition.

Observations from growers who used SOURCE

  • Earlier, more uniform crop maturity
  • Healthier, more robust root systems
  • Less firing, more greenness within the canopy
  • Bigger ear size
  • Better grain fill and kernel count
  • Greater standability
