PUSA Biophos (PSB-Liquid Formulation)
Background:
Phosphorus (P) is an essential element determining plants’ growth and productivity. Due to soil fixation of P, its availability in soil is rarely sufficient for optimum growth and development of plants. As modern agricultural producers rely heavily on fertilizer use to supply crops with necessary nutrients and achieve higher yields, the prices in food and fertilizer markets are naturally strongly correlated. India doubled imports of P-fertilizer (DAP) in 2008. So, apart from chemical P- fertilizers being costly, they are also polluting the soil and reducing the soil fertility. An eco-friendly alternative to this problem is the Phosphorus Biofertilizers like PSB; (Phosphorus Solubilizing Bacteria).
Technology Details:
Owing to its high reactivity with almost anything which it contacts, phosphorus has a lower mobility than any other nutrient. It can be bound up by soil organisms, by mineral elements (particularly aluminum, calcium and iron), and by clay minerals containing aluminum or iron. Consequently, phosphorus does not remain in a free state for long, and any amount is taken up by plants usually comes from an area within a fraction of an inch around the roots. Phosphorus solubilizing bacterium (PUSA Biophos) is a microbe with an inherent capability of solubilizing the unavailable form of P into a soluble form so that it can be up taken by the growing crop. The biofertilizer has been tested in many crops under field and pot conditions and found to improve the P-nutrition of the plant.
