2020 Yield Testimonials


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 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.

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.
