Lawrence Hurst of Plymouth, Ohio has tried SumaGroulx, SumaGrow Inside on spring wheat and hay in 2013. Lawrence used SumaGroulx, SumaGrow Inside on one field, while his father did another in their regular way. At harvest, the SumaGroulx, SumaGrow Inside field went 82 bushel while dad’s field went 74 bushel. They also got 840 bales of straw off 110 acres which Lawrence says is EXTREMELY good. They seeded hay to 2 fields. Dad’s field was done two weeks prior to Lawrence, but the SumaGroulx field has already passed in height and has an overall healthier look to it. Lawrence is very impressed.
