Between 2012-13, an independent grower conducted a trial using GrowPlex™ on field corn in Muscatine, Iowa.
The trial consisted of one treatment each year. The first treatment, Control, included the Grower’s standard fertility program. The second treatment, GrowPlex, included the Grower’s standard fertility program and GrowPlex® added at a rate of 4 oz per acre at planting and 4 oz per acre at sidedress.
Treated rows experienced as much as a 13% increase in dry bushel weight with GrowPlex® compared to the control.
Treated rows experienced early health and vigor, which carried through to harvest and resulted in higher yield and net return.
