JH Biotech - Soluphos SP | Phosphate Solubilizing Inoculant
Brand: JH Biotech
Soluphos SP
OMRI Listed | CDFA OIM
Soluphos SP is a powder-form phosphate solubilizing microbial inoculant containing microbial food, Bacillus licheniformis, and Pseudomonas putida. Phosphorus stimulates root development, increases stalk and stem strength, and improves production and crop quality, but soil elements often tie it up into an unusable form. Soluphos SP uses its bacteria to free locked phosphorus from the soil and release it to plants, improving fertilizer efficiency and increasing yields.
Use on all agricultural and ornamental crops as a seed coating, root dip, bulk soil mix, side dress, or through irrigation systems. Root dipping is 1 lb in 6 gallons of water. Sub-surface and drip irrigation is 1 to 2 lbs per acre repeated every 30 days. Side dress is 1 to 2 lbs per acre applied within 24 hours of mixing.
