Nitrogen Fixation was proved to increase the growth of clover plants over a ten-week experiment in Nitrogen deficient conditions. The Hypothesis was proved correct with no difficulties encountered.

Nitrogen is approximately 78% (volume) of dry air. It is present in the protoplasm of living matter and the compounds contained in Nitrogen (Nitric Acid, Explosives, Cyanides, Fertilisers and Protein) are necessary to the continuation of life. Nitrogen is an essential constituent of Amino Acids that form Protein, which builds protoplasm. Although Nitrogen is about 78% (volume) of dry air this gaseous Nitrogen can't be used by animals or plants. The Nitrogen must be 'Fixed' and turned into compounds such as Ammonia or Nitrates, which can be used. This is where Nitrogen Fixation comes in.

Nitrogen Fixation is the term to describe the reduction of atmospheric Nitrogen to Ammonia. Nitrogen Fixing bacteria live in the roots of Leguminous plants like beans peas and clover. The bacteria enter the plants through it's root hairs and cause cells (cortical) of the root to proliferate which causes swelling called a Root Nodule. Vascu

The association between Legume - Rhizobium is very specific, as I mentioned before Rhizobium cannot fix Nitrogen without legumes and vice versa nor can it fix Nitrogen with soybeans or lupins because it can't nodulate with other species. I believe that once this hurdle is over come scientists will be able to produce Nitrogen Fixation with useful crops so that our productivity is greater.
