BIO-NPK is a unique organic supplementation of noble soil bacteria, isolated by Assam Agricultural University, Jorhat (AAU) from the native soil of the state.

These microbes, Azotobacter, Azospirillum, PBS, KSB, Rhizobium, Zinc solubilizing bacteria & Pseudomonas,regulates basic plant metabolism by providing Nitrogen, Phosphorus, Potassium and Phytohormones.  

This bacteria are able to produce phytohormones, including cytokinins, auxins, gibberellins, ethylene and absacic acid ( ABA ), which play a role in different growth processes in plants including cell multiplication, which results in increased cell and root expansion. This bacteria has the ability to increase the availability of nutrient concentration in the rhizosphere by fixing nutrients, thus preventing them from leaching out. This bacteria showed to increase root proliferation over a short period of time, thus increasig the uptake of nutrients and water holding capacity of the plants.
