BIO-PSB is a microbial inoculant formulated with efficient phosphate-solubilising strains that release phosphorus from rock phosphate, organic complexes and soil minerals. These bacteria produce organic acids, enzymes and other metabolites that solubilise bound phosphorus, increasing its availability for root uptake. Improved phosphorus nutrition promotes vigorous root systems, early crop establishment and stronger vegetative growth.
Application modes include seed treatment, soil application or fertigation per crop need. Typical seed treatment: 10 ml per kg seed. For soil or drip systems follow the product leaflet for crop-wise ml/L recommendations. BIO-PSB works well with other biofertilisers to improve overall nutrient cycling and help reduce dependence on bulky chemical phosphate inputs.
