Spot Where Nothing Would Grow

“This area of our field wouldn’t grow crops, not even weeds.  In the early spring, we applied 5 gal Sure Crop Humate, 1 gal Sure Crop Plen-T Sweet, 13 oz Sure Crop Z/Micro and 1 gal Sure Crop Complete with old hay and manure.  Later that summer, we grew soybeans where nothing was able to grow before!”

Humate / Penetrometer Readings

“There was no yield monitor to judge yield by, but the side with Humate was more uniform in height and they felt that it was healthier than the side with no Humate, which should result in a better yield.”
