BOSS PheNom is nitrogen fixing biological bacteria blend that is applied foliar.

Elevate Crop Vitality with Endophyte Bacteria for Enhanced Nitrogen and Phosphorus Uptake

BOSS™ PheNom consists of two endophyte bacteria. These bacteria live inside the plant (endophyte) not in the soil. When applied foliar the bacteria enter the plant when it comes in contact with the stoma on the leaves, stalk, stems and roots. After entering the plant, the bacteria move throughout the plant and live inside the stoma. The stoma is the openings where your plant breathes. When your plant breathes BOSS™ PheNom is pulling nitrogen out of the air (N2) and converting the N2 to NH4. The NH4 is feeding your crop. This greatly increases your nitrogen availability to your crop. The other bacteria lives in the roots and causes the root to process and metabolize phosphorus faster and more efficiently.
If you are wanting to increase the supply of nitrogen and increase phosphorus efficiency to your crop, try BOSS™ PheNom.
