Unlock Soil Phosphorus and Boost Plant Growth with Phosphate Solubilizing Bacteria (PSB) Phosphate Solubilizing Bacteria (PSB) are beneficial microorganisms that help unlock and solubilize the phosphorus present in the soil, making it more accessible to plants. Phosphorus is a vital nutrient that plays a key role in root development, flower formation, fruiting, and overall plant health. However, much of the phosphorus in the soil is often bound in insoluble forms, making it unavailable to plants. PSB works by breaking down these insoluble phosphorus compounds, converting them into a form that plants can readily absorb. This enhances nutrient uptake, improves soil fertility, and promotes healthy plant growth.
