BioPhos+ - Phosphorus-Solubilizing Biofertilizer
Not all soil phosphorus is readily available to plants. BioPhos+ converts less-accessible forms of soil phosphorus into forms plants can easily absorb. It is a water-soluble microbial biofertilizer that can be used in various applications, including soil drenches, seed treatments, root-zone applications, compost tea preparations, and larger growing operations.

Simple Ways to Use
Whether you're working with garden beds, compost tea, or larger growing areas, BioPhos+ can be incorporated into different soil-focused applications.
* Apply to the soil or root zone rather than as a foliar spray. Use the appropriate directions for the chosen application method.
Mix 1 teaspoon per gallon of water and apply to the soil around the root zone.
Apply once or twice per month.
Add 2 teaspoons of BioPhos+ to a 5-gallon bucket of compost tea.
- Seed Treatment: Apply ¼ lb per 100 lb of seed.
- Field & Bed Preparation: Apply ¼–½ lb during tilling before planting or during the growing season.
Apply ½–2 lb per acre, depending on soil quality and crop type.
Why BioMend+
Phosphorus can be present in soil without being readily accessible to plants. BioPhos+ introduces specialized microorganisms designed to work with this existing phosphorus through biological processes.

Helps convert certain less-accessible soil phosphates into plant-available forms
Combines four microorganisms in one targeted microbial formula
Offers a biological complement to conventional nutrient management
Water-soluble powder for convenient mixing and application
Versatile for soil preparation, seed treatment, and root-zone applications
FAQ
What is BioPhos+ and how does it work?
BioPhos+ is a microbial biofertilizer containing phosphorus-solubilizing microorganisms. These microorganisms are associated with processes that convert certain less-accessible forms of phosphorus into forms available for plant uptake.
Is BioPhos+ the same as a phosphorus fertilizer?
No. Conventional phosphorus fertilizers supply phosphorus as a nutrient. BioPhos+ contains microorganisms intended to help make some of the phosphorus already present in soil more available. It is a biological input, not a replacement for every phosphorus fertilizer application.
What types of plants can I use BioPhos+ on?
BioPhos+ is designed for a wide range of crops, including vegetables, herbs, flowers, shrubs, fruit and nut trees, vines, grains, legumes, and row crops.
Can I use BioPhos+ when planting or starting seeds?
Yes. BioPhos+ can be used during soil preparation and as a seed treatment. For seed treatment, the supplied application guide recommends ¼ lb per 100 lb of seed. It can also be applied to the root zone during planting.
