Azotobacter Biofertilizer

Free-living Azotobacter chroococcum biofertilizer capable of fixing 20-40 kg N/ha/year in the rhizosphere of non-leguminous crops. Unlike Rhizobium, Azotobacter does not require symbiotic nodulation — it fixes nitrogen independently in the soil surrounding crop roots. Also produces growth-promoting substances including IAA, gibberellins, and vitamins. Effective for cereals, vegetables, cotton, and sugarcane.

Product Overview

Azotobacter Biofertilizer contains free-living Azotobacter chroococcum bacteria capable of fixing 20-40 kg nitrogen per hectare annually without requiring symbiotic root nodulation. Unlike Rhizobium which only works on legumes, Azotobacter fixes atmospheric nitrogen independently in the soil surrounding any crop’s root zone — making it suitable for cereals, vegetables, cotton, sugarcane, and all non-leguminous crops. Additionally, Azotobacter produces plant growth-promoting substances including indole-3-acetic acid (IAA), gibberellins, cytokinins, and B-vitamins that stimulate root growth and improve overall plant vigor.

How Azotobacter Biofertilizer Works

Azotobacter chroococcum is an aerobic, free-living diazotroph that fixes atmospheric N₂ using the nitrogenase enzyme complex powered by soil organic carbon as an energy source. The bacteria thrive in the carbon-rich rhizosphere zone surrounding plant roots. Fixed nitrogen is released into the soil solution as the bacterial cells die and decompose, becoming available for crop uptake. Simultaneously, the growth hormones produced (IAA, GA₃) stimulate root hair development, increasing the crop’s own nutrient and water uptake capacity.

Key Benefits

Fixes 20-40 kg N/ha/year in any crop’s rhizosphere

Works on ALL crops — not limited to legumes

Produces IAA, gibberellins, and cytokinins for root growth stimulation

Improves soil biological activity and organic carbon cycling

Compatible with organic and integrated farming systems

Reduces synthetic nitrogen requirement by 15-25%

Enhances seedling vigor and transplant establishment

Available in powder and liquid formulations

Application Guide

Seed treatment: mix 200g per 10kg seed with a sticker solution. Soil application: apply 2-5 kg/ha in furrow at planting. Seedling dip: prepare 500g in 10L water, dip seedling roots for 15-30 minutes before transplanting. Fertigation: dissolve 1-2 kg/ha in irrigation water. Apply to moist soil — Azotobacter requires aerobic conditions and adequate moisture. Best results in soils with pH 6.0-7.5 and organic carbon >0.5%.
