AgroAzzo

Nitrogen-Fixing Azotobacter chroococcum

AgroAzzo is a concentrated microbial inoculant containing Azotobacter chroococcum, a beneficial free-living soil bacterium capable of biological nitrogen fixation.

By converting atmospheric nitrogen into biologically available forms, Azotobacter can contribute to nitrogen cycling within the rhizosphere and support crop growth as part of an integrated nutrient management programme.

Key Benefits

• Supports biological nitrogen fixation
• Promotes nitrogen cycling within the rhizosphere
• Supports root development and crop growth
• Complements conventional crop nutrition programmes
• Suitable for a wide range of agricultural and horticultural crops

How AgroAzzo Works

Azotobacter chroococcum is a free-living nitrogen-fixing bacterium that can colonise the soil and rhizosphere without requiring the specialised root nodules associated with legume–Rhizobium systems.

Under suitable conditions, Azotobacter converts atmospheric nitrogen (N₂) into biologically available nitrogen compounds, contributing to nutrient cycling around the developing root system.

AgroAzzo provides a concentrated source of A. chroococcum for incorporation into crop nutrition and biological soil programmes.

Microbial Specification

Azotobacter chroococcum

Contains no less than 1 × 10⁸ CFU/mL at manufacture.

Application Guide

AgroAzzo can be applied as a seed treatment, in-furrow application or soil drench, allowing it to be incorporated into a range of cropping programmes.

Seed treatment: 0.5–1 L per 100 kg seed
In-furrow: 2 L/ha
Soil drench: 3–5 L/ha

Suitable for pasture, cereals, forage crops, vegetables, horticultural crops and other production systems.

Integrating Biological Nitrogen Fixation

AgroAzzo is designed to complement sound nitrogen management rather than act as a direct replacement for all applied nitrogen.
