2020 Yield Success Stories
TERRASYM FOR CORN
Terrasym 408
“When I examined the treated and untreated roots, I noticed a lot of finer hairs on the plant that was treated. Around August, I called another farmer and said, ‘Hey, I've never seen soybeans filled to the top like this - just this stack full of pods.’ We went in the field, circled out a 30-acre spot, and could see a five to six bushel yield advantage on the Terrasym treated soybeans.”

TERRASYM FOR CORN
Terrasym 450
“My farm is poorly drained and has wet soil, so we chose to use Terrasym 450 to help improve our yields. We've collected the last five years worth of yield data. After using Terrasym, we beat it by 10 bushels. But we did make one mistake: We didn't do the whole thing. We should've used both sides of the planter.”
—Steve Johnson;
Ames, IA
TERRASYM FOR SOYBEANS
Terrasym 401
“When I think of Terrasym, I think of all the science behind it. Everything at NewLeaf Symbiotics is PhD-driven. They’re actually creating a product – and constantly working to better it.”
