Learn more about BOSS PheNom ST

BOSS PheNom ST is a patented biological seed treatment. This product is easy and safe for you to use at a 2oz/100# of seed rate.

BOSS PheNom consists of two patented endophyte bacteria. These bacteria live inside the plant (endophyte) not in the soil. One bacteria lives above ground in the leaves and the other lives below ground in the roots. The bacteria in the leaves grows in the stoma, the opening where your plant breathes. When your plant breathes BOSS PheNom is pulling nitrogen out of the air and feeding your crop. This greatly increases your nitrogen availability to feed your crop. The other bacteria, living in the roots causes the root to solubilize phosphorus that is tied up in the soil.
All soils tie up phosphorus. The pH of your soil determines how much phosphorus is tied up and not available to feed your crop.
If you are wanting to increase the supply of nitrogen and phosphorus to your crop try BOSS PheNom.
