Increase micronutrient availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P2O5.
Encourage faster root growth for water and nutrient uptake.
PSB produces organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P2O5 uptake, maturity and increase yield.
Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.
