Azospirillum Brasilense Bacteria (Azos) And Why Every Gardner Needs It.

Once again this is an example of how one must feed the SOIL not the plant. Nature has already thought of everything you need and provided it somehow, all you have to do is learn to restore what has been lost. Many fungi and bacteria have been killed off by spraying and other pressures of modern Western life. So here is a knowledge bomb of one of the hardest working bacteria in your garden, and maybe on the planet,

Azospirillum Brasilense, commonly referred to as Azos or A.Brasilense, is one of the most well-studied plant growth promoting bacteria. It is considered a free-living soil bacterium that has the ability to affect the growth of numerous agricultural crops worldwide through the excretion of various hormones and the bacteria’s ability of nitrogen fixation.

Pull Nitrogen From Thin Air.

Even though you and I breath oxygen and plants breath carbon dioxide, the atmosphere is actually comprised of around 80% nitrogen which is in the form of N2 atmospheric nitrogen that is not conventionally available to plants. Nitrogen is a key component in growing anything. it drives chlorophyll production keeping the plants dark green and happy. It is a huge part of amino acids and other compounds that keep your plants strong and healthy. It is a part of every major protein molecule, and yet soil is often lacking enough N. Chemical fertilizer could provide this N, but they are expensive and can be dangerous.


Somewhere along the evolutionary development of the “Plant – Soil – Microbial Matrix”, certain bacteria began to specialize in tasks to enhance plant growth, which in return provided the microbes with a food source exchange opportunity.  A select group of bacteria classified as “Diazotrophs” began to supply nitrogen to plants from a range of sources, including decomposed plant litter, dead micro-organisms, and sequestration of atmospheric nitrogen.

Azos is a particularly efficient agent originally isolated in the Amazon Basin where the lack of soil, the reapid breakdown of any vegetation by hungry microbes, and the environmental conditions which require growth to survive is a fundamental proposition of the ecosystem. Azos specialized in the highly-efficient conversion of the N2 form of nitrogen into plant-available NH3 ammoniacal nitrogen. Azos is so efficient that between 50-percent and 70-percent of all the nitrogen required by most crops can be supplied by this organism. Azos benefit to plants is not limited nitrogen-fixation alone. Azos also acts as a growth simulant, catalyzing the release of a natural growth hormone in plants. This naturally-released hormone increases root development and optimized the harvest potential of your garden. Together, Azos and mycorrhizae fungi work symbiotically to help ordinary plants become the fullest they can be (read about mycorrhizae in this post).

Azos can be used as a cloning solution, though I have not tried it personally.

So grab some for your spring transplants and improve your crop this summer.
