Green Phospho is a microbial biofertilizer containing Phosphate Solubilizing Bacteria (PSB) — beneficial soil microorganisms that unlock locked phosphorus in the soil and make it directly available to plants. PSB convert insoluble phosphorus present in soils into available phosphorus that can be directly absorbed and utilized by plants through secretion of enzymes, organic acids, and chelating compounds.

What is Green Phospho?Green Phospho is a microbial biofertilizer containing Phosphate Solubilizing Bacteria (PSB) — beneficial soil microorganisms that unlock locked phosphorus in the soil and make it directly available to plants. PSB convert insoluble phosphorus present in soils into available phosphorus that can be directly absorbed and utilized by plants through secretion of enzymes, organic acids, and chelating compounds. PubMed CentralThe Problem It SolvesOnly 1.00–2.50% of the total phosphorus content in soils is plant-available, which seriously affects the growth of plants and the development of agriculture — resulting in high levels of total phosphorus in soils yet a scarcity of available phosphorus. PubMed Central Green Phospho bridges this gap naturally, without chemical intervention.Key FeaturesUnlocks Soil Phosphorus — Phosphate solubilizing bacteria increase the solubility of phosphorus through the secretion of organic acids, ScienceDirect releasing the phosphorus already locked in the soil.Boosts Crop Yield — Application of PSB biofertilizer increases crop yield ranging from 10% to 40% depending on the type of crop and soil. ScienceDirectSaves on Chemical Fertilizers — Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg/ha P₂O₅, or 50% of the need for phosphatic fertilizers. WikipediaStimulates Root & Plant Growth — PSB synthesize phytohormones, increase trace element availability (Zn and Fe), and improve root and shoot length, enhancing phosphorus availability to crops. PubMed CentralImproves Stress Tolerance — Increased phosphorus availability activates stress-responsive genes in plants, enhancing their ability to tolerate drought, salinity, heavy metal toxicity, and temperature extremes. FrontiersEnhances Nitrogen Fixation — Bioavailable phosphates positively affect the symbiosis of legumes and rhizobia, improving conditions for nodulation and increasing the efficiency of nitrogen fixation. PubMed CentralEco-Friendly & Cost-Effective — PSB are recognized as a cost-effective, environmentally friendly, and long-term biological solution to address soil phosphorus deficiency. ScienceDirectHow It WorksThe mechanism of mineral phosphate solubilization by PSB is associated with the release of low molecular weight organic acids, through which their hydroxyl and carboxyl groups chelate the cations bound to phosphate, thereby converting it into soluble forms.
