Its property of nitrogen fixation has been put to experimental use.

I. Nitrogen fixation in the dead leaves of forest beds.

This work provided some of the first molecular models for nitrogen fixation.

The entire plant is known for soil improvement because of nitrogen fixation.

Outside sources are considered to be upwelling from deep water or by nitrogen fixation.

Nitrogen fixation occurs naturally in the air by means of lightning.

It is used to study the symbiosis responsible for nitrogen fixation.

Cobalt is thought to be an important catalyst in nitrogen fixation.

What are the prospects for nitrogen fixation in plants?

Future benefits from biological nitrogen fixation: An ecological approach to agriculture.

One example of a non-biological process responsible for nitrogen fixation is lightning.

This species has been documented as carrying out nitrogen fixation, unusual for a plant in its family.

The root structures provide nitrogen fixation moving nutrients from the air into the soil.

The hesB gene is expressed only under nitrogen fixation conditions.

Nitrogenase is the most important enzyme involved in nitrogen fixation.

Biological nitrogen fixation was discovered in this lake in 2007.

Nitrogen fixation is an important part of the nitrogen cycle.

Therefore nitrogen fixation is essential for agriculture and the manufacture of fertilizer.

Its roots also encourage nitrogen fixation, which produces higher crop yields.

Nitrogen fixation has been demonstrated in some strains of B. megaterium.

Biological nitrogen fixation: Investments, expectations and actual contributions to agriculture.

Nitrogen Fixation is one of the most beneficial processes performed by rhizobacteria.

Until modern times, nitrogen fixation was the major source of nitrogen for ecosystems.

Cluster I contains most of the nitrogen fixation genes.
