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.

The Pathways of Nitrogen Fixation
1972Publisher Summary Biological nitrogen fixation is the enzymic reduction of atmospheric nitrogen to ammonia. Along with the scientific interest of nitrogen fixation as a fundamental biochemical reaction, it is also of great ecological and agricultural importance because it is the most important source of the metabolizable nitrogen needed by all living

This paper discusses the processes of nodulation and nitrogen fixation among Leguminosae tree species usually used in different agroforestry systems. Also included are the microbiological methods for studying rhizobia, the different methods used in determining whether a legume could fix nitrogen, isotope-based methods for nitrogen fixation measurement,

The assignment to give an overview of biological N2 fixation implies that we should spend a little time in discussing the history of the subject. It is somewhat over 90 years now since Hellriegel and Wilfarth clearly indicated that biological N2 fixation occurs in leguminous plants.

Regulation of Nitrogen Fixation
1978Publisher Summary This chapter discusses the regulation of nitrogen fixation. Both the biosynthesis and the activity of nitrogenase are regulated. The product of N2 reduction, ammonia, through its effect on the biosynthesis of glutamine synthetase, represses nitrogenase synthesis but has no effect on nitrogenase activity.

Biochemical Genetics of Nitrogen Fixation
Microbiological Reviews, 1980This chapter will introduce the subject of nitrogen fixation and will stress the biochemical aspects. Subsequent papers on nitrogen fixation in this volume will focus on the molecular biology and regulation of the system in several different organisms.

Abstract The International Biological Programme served as a focal point for studies on biological nitrogen fixation during the 1960s. The introduction of the acetylene reduction technique for measuring nitrogenase activity in the field led to estimates becoming available of the contribution of lichens, blue-green algae, nodulated non ...
