40 ROCK®

Zinc Infused Homogeneous Pellets

Balanced levels of zinc within the soil are critical in the growing process, and vital for the biochemical pathways of healthy plants. Zinc deficiencies lessen plant quality and reduce crop yields. With 40 ROCK®, the J.R. Simplot Company has developed a novel homogeneous pellet to deliver zinc uniformly throughout the soil.
Easily adapted to a wide range of application practices including: broadcast, banded, grain drills and side-dressed. Blends well with other N, P and K fertilizers for custom dry blends.

Directions and Usage

1. Is an ideal combination of N and P2O5 for use as a starter fertilizer on small grains, row crops, tree crops and forages. The monoammonium form reduces the risk of fertilizer injury to germinating seeds.

2. Chemically compounded N and P2O5. The ammonium phosphate combination in each pellet enhances the uptake of phosphate by the plant. The highly water soluble phosphate goes to work quickly allowing efficient utilization by plants. The ammoniacal form of nitrogen reduces nitrogen losses by leaching.

3. Has a slight acidic effect, which helps counteract nutritional problems in calcareous soils

4. This product is a commercial fertilizer used as plant food in agricultural crop production. For specific application rates follow the recommendation of a qualified individual or institution, such as, but not limited to, a certified crop
advisor, agronomist, university crop extension publication, or apply according to recommendations in your approved nutrient management plan.
