Science, 1973
Nitrogen fixation, measured by the reduction of acetylene to ethylene, was found in workers of the dry-wood termite Kalotermes minor . The soldiers and reproductive castes fixed little or no nitrogen. The fixation rates ranged between 24 and 566 micrograms of nitrogen fixed per month per gram (wet weight) of termite.

Genetic analysis of nitrogen fixation in free-living bacteria is being used to elucidate processes which in the plant root depend on a complex symbiotic relationship. Increased understanding of the nitrogen fixation mechanism will eventually help to increase the world resources of protein.

Science, 1959
Incorporation of N 15 into the fixed nitrogen fraction of natural lake waters has been studied for the purpose of estimating rates of primary nitrogen fixation. Experiments in Pymatuning Reservoir, Pennsylvania, in Lake Mendota, Wisconsin, and in two lakes in Alaska indicate that fixation occurs at measurable ...

Annual Review of Nutrition, 1993
Biological nitrogen fixation (BNF) is the process of the reduction of dinitrogen from the air to ammonia carried out by a large number of species of free-living and symbiotic microbes called diazotrophs. BNF presents an inexpensive and environmentally sound, sustainable approach to crop production and constitutes one of the most important Plant Growth ...

Nitrogen Fixation and Nitrogen Fertilization of Soybeans
Isotopes in Environmental and Health Studies, 1996Abstract In pot experiments with (15)N labelled soil and mineral (15)N, the influence of Bradyrhizobium (Rhizobium japonicum) inoculation and N fertilization on the symbiotic N(2) fixation and yield of soybeans [Glycine max (L.) Merill., cv. 'Fiskeby V'] was investigated.
