“I got 260 bushels per acre!”

“In 2015, I used SumaGroulx on my all of my corn fields. I got 260 bushels per acre! That was a 17% increase from last year. I had used SumaGroulx the year before as well. The other advantage is that I do not have the expense of fertilizer now. It is a great product and would recommend it to anyone.”
