In 1997, researchers at the University of California, Merced conducted a trial using Menefee Humate™ and GrowPlex™ on cotton in the San Joaquin Valley, California.
The trial consisted of two treatments. The first treatment, Control, was the grower’s standard fertility program. The second treatment, Menefee Humate & GrowPlex, had 100 lbs of Menefee Humate™ per acre added at planting. GrowPlex™ was added at 2 oz per acre for two applications
Treated rows experienced a 15.4% increase in lint yield with Menefee Humate™ and GrowPlex™.
Rows treated with Menefee Humate™ and GrowPlex™ showed more consistent sizing and health.
