Treatment Options

Apply a good fertility program in the soil with enough Nitrogen to fulfill the targeted yield goals. Complement with a foliar program containing high percentage of Nitrogen especially when farming a light textured or sandy soil; dealing with compacted soil or a soil with low organic matter. Also, water logged conditions create high demand on Nitrogen.
