As you know, it is common to see that many of the biofertilizers and biostimulants that we use for our plants or trees stand out for their ability to fix nitrogen. But why fix nitrogen favors crops? Basically because it promotes its growth. When we talk about fixation we refer to having assimilable nitrogen for crops.
It is known that crops basically need phosphorus, potassium and nitrogen to prosper. But the latter represents 78% of the air in our atmosphere and, therefore, is a source of life. That is why nitrogen is part of many of the biofertilizers, as is the case with some products from our line of amino acid-based formulations (Aminon Forte and Aminon WSP) and with the Folimax line of foliar correctors.
Biological fixatión of nitrogen (FBN)
To this we must add that there are some plant species (such as legumes) capable of capturing nitrogen by the action of bacteria that live in their roots. This allows them to convert gaseous nitrogen from the air into inorganic nitrogenous compounds. In other words, that nitrogen that can be assimilated by them is ready to be used as part of the chlorophyll molecules and, therefore, as a source of nutrients for their growth.
Title
Nitrogen as part of amino acids contributes to building proteins involved in metabolism and energy storage. When biological nitrogen fixation is inadequate, a nutritional deficiency occurs that harms the plant nutrition process. The result: a plant with poor growth and an unvital appearance.
Also it is that Biological Nitrogen Fixation (or FBN) allows to naturally reduce the use of industrial nitrogen fertilizers without affecting the yield and sustainability of crops. In other words, it is beneficial for agriculture and for the environment.
That is why it is so important to continue advancing in the study and application of soil bacteria that are
efficient for the FBN process. To improve the use of land, preserve the environment and guarantee
adequate and quality food production.
However, it is also the most complicated to handle. For nitrogen to be available to plants, it must first be reduced to ammonia; it is what we mean when we talk about nitrogen fixation. This biological process is
carried out by certain bacteria. They are the diazotrophs, which include:
- rhizobia
- azotobacter
- azospirillum
- frankia alni
- and cyanobacteria
Also it is that the lack of nitrogen prevents an optimal development of plant species. It is estimated that
90% of nitrogen fixation is biotic and is produced by soil microorganisms. Hence the importance of that
symbiotic relationship that we mention so many times.
In fact, we recently made known through our social networks the research we carried out with the
𝘼𝙯𝙤𝙨𝙥𝙞𝙧𝙞𝙡𝙡𝙪𝙢 𝙗𝙧𝙖𝙨𝙞𝙡𝙚𝙣𝙨𝙚. This pink-orange bacterium, associated with the production of carotenoids, has
a high performance to fix nitrogen and create growth phytohormones such as auxins. Here you can see it
