Biofertilizers make nutrients that are naturally abundant in the soil or atmosphere that can be used for plants. They are effective and inexpensive inputs, free from the adverse environmental implications carried by chemicals.
Biofertilizers offer new technologies for agriculture, holding the promise to balance the many shortcomings of conventional chemical-based technology. You can check this out organitek.com/ if you are looking for fertilizers.
Biofertilizers, better known as microbial inoculants, are selected cultures of soil organisms that can increase soil fertility and plant productivity.

The commercial history of biological fertilizers began with the launch of 'Nitragin', Rhizobia's laboratory culture in 1895. The discovery of Azotobacter followed then blue-green algae and a number of other microorganisms. Azospirillum and Vesicular-Arbuscular Mycorrhizae (VAM) are fairly recent discoveries.
Rhyzobium (RHZ): This inoculant is known for its ability to fix atmospheric nitrogen in a symbiotic relationship with plants that form nodules on the roots.
Azotobacter (AZT): This is beneficial for a variety of plants including cereals, millets, vegetables, cotton, and sugar cane. These are free-living, non-symbiotic nitrogen-fixing organisms that also produce substances that are good for plant growth, and antibodies that suppress many root pathogens.
Azospirillum (AZS) :): This is also a nitrogen-binding microorganism that is beneficial for non-leguminous plants. Like AZT, the benefits extend beyond nitrogen enrichment through the production of substances that promote growth.
