In the winter of 2012, I heard about SumaGroulx. After meeting and talking to the consultants, I decided to cut back on my starter by 50% and my liquid 28 by 20%. After talking to the advisors again I took my starter out 100% and my liquid 28 by 20%. I did this on 500 acres of corn. The savings on the 500 acres of corn was $30,000 on my fertilizer bill. To my amazement, I had a rise in yield even with a 5 week drought. I plan on using SumaGroulx on all my corn, wheat and fruit trees in 2013.
