LEGUMES AND NITROGEN FIXATION —SOUTH AUSTRALIA

Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia (NH 3) or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen (N 2) is relatively inert: it does not easily react with other chemicals to form new compounds.

Plant Growth-Promoting Nitrogen-Fixing Enterobacteria Are

Biological Nitrogen Fixation (BNF) is known to be a key to sustain agriculture and to reduce soil fertility decline. Research on microorganisms and plants able to fix nitrogen contributes largely to the production of biofertilizers. Thus it is important to ensure that BNF research and development will take into account the needs of farmers in the developing countries mainly. UNESCO has already

Legumes and Nitrogen Fixation LEGUMES AND NITROGEN FIXATION —SOUTH AUSTRALIA Background All plants are able to take up nitrogen from the soil in the form of ammonium (NH 4 +) or nitrate (NO 3-); together these are known as available N. In addition to taking up available N from the soil, legumes (clovers, medics, peas and beans) are also able to acquire N from the abundant supply …

Biological nitrogen fixation by common beans Phaseolus

All plants, including forage crops, need relatively large amounts of nitrogen (N) for proper growth and development. Biological nitrogen fixation (BNF) is the term used for a process in which nitrogen gas (N 2) from the atmosphere is incorporated into the tissue of certain plants.
