I used SumaGroulx on my wheat, corn, and beans and was very impressed with how the corn is taking off right now (Sept. 2013). I can’t wait to see what the results are at harvest time. My wheat was 10-15 bushel per acre better with SumaGroulx and I am going to put it on my fall wheat and cover crops.
What brought me to use SumaGroulx was the potential of cutting fertilizer costs and increasing yields and so far I have been very impressed with the product overall! I certainly understand that we still have to get the right kind of weather at the correct times to get “over the top” yields, but in a dry year if I can maintain the previous year’s yield I can’t expect a lot more than that.
