GreenGro Biologicals CoastBio BioPhos+ Phosphorus-Solubilizing Biofertilizer

Help Plant Roots Access Phosphorus Already in the Soil

CoastBio BioPhos+ is a water-soluble microbial powder for vegetables, flowers, shrubs, vines, and fruit and nut trees. The microbes help dissolve mineral phosphates and release phosphorus from organic matter so roots can absorb it.

Ways to Apply BioPhos+

• At planting — Treat seeds before sowing, dip transplant roots in a BioPhos+ solution, or apply it directly to the root zone.
• In soil and fertilizer blends — Mix the powder into potting soil or incorporate it into a dry fertilizer blend.
• Through irrigation — Dissolve the powder in water for fertigation or hydroponic use.

BioPhos+ uses dextrose as its carrier and comes in 1 lb and 5 lb sizes. It is registered with the California Department of Food and Agriculture (CDFA) as an Organic Input Material, registration #826418.
