AZOS® Red Liquid
Nitrogen-Fixing Bacteria

Biological nitrogen fixation is an important source of nitrogen in agriculture and represents a promising substitute for nitrogen fertilizers. The free-living diazotrophic bacteria, Azospirillum brasilense, has the ability to convert atmospheric nitrogen into ammonia, contributing to the pathway that increases available nitrogen for plants.


AZOS Red Liquid is a concentrated bacterial formulation of A. brasilense, freshly produced only when ordered to ensure the highest product viability. AZOS Red Liquid can be used with all major agricultural crops and applied through various methods of application. 

Nitrogen is required in the greatest amount of all nutrients transported to plants through the soil. It drives chlorophyll production in the foliage and keeps plants green and growing efficiently. AZOS® (Azospirillum brasilense) is a naturally occurring bacteria that live symbiotically with a host plant and supplies necessary nitrogen. 

How does AZOS Red Liquid work?

Our atmosphere is made up of 80% nitrogen. AZOS absorbs this nitrogen as N2, converts it to a form that the plant can use and supplies it to the plant efficiently. 


Recommended single treatment on brassicas and co-treatment with MYKOS on most cereal & vegetable crops. Can be applied through drip line, tape, and most irrigation applications.
