    Through the process of biological nitrogen fixation (BNF), symbiotic and nonsymbiotic organisms can fix atmospheric N 2 gas into organic N forms (Figure 1).A few living organisms are able to utilize molecular N 2 gas from the atmosphere. The best known of these are the symbiotic Rhizobia (legume bacteria), nonsymbiotic free-living bacteria such as Azotobacter and Clostridium, and blue-green algae.

Symbiotic biological nitrogen fixation is such an alternative and has been used for years in agriculture.

One family of plants, the Leguminosae, has evolved a symbiotic relationship with specific. Biological nitrogen fixation (BNF), a microbiological process which converts atmospheric nitrogen into a plant-usable form, offers this alternative.

Nitrogen-fixing systems offer an economically attractive and ecologically sound means of reducing external inputs and improving internal resources. Biological Nitrogen Fixation (BNF) is a low-cost technology with potential to contribute to sustainability of African agriculture where low-input production systems are prevalent.

Biological Nitrogen Fixation estimate the amount of fixed nitrogen and to select the most effective rhizobial strain x plant genotype combination. The 15N techniques are currently the most accurate method to measure the nitrogen fixed in a given system. The elite strains will be then used for the inoculum production.

NITROGEN AND TROPICAL AGRICULTURE SUMMARY As a key component of proteins, nitrogen is essential for all life.

Nitrogen moves in a cycle from the atmosphere into the soil and plant system, through the food chain of animals and This process is called biological nitrogen fixation (BNF).

Wilson. This book, which is of interest to students, research workers and professionals, aims to present a synthesis of research on biological nitrogen fixation relevant to tropical agriculture.

A comprehensive review is given of the main nitrogen-fixing grain crops, fodder plants and tree species, showing how the inputs of nitrogen can be most efficiently utilized for sustainable agricultural.

Nitrogen Fixation. Nitrogen fixation is the natural biological process, by which nitrogen (N2) in the atmosphere is converted into ammonia (NH3). Humanity depends on fixed nitrogen to fertilise croplands, and helping nature in relation to nitrogen availability is a key aspect of world food security.

Biological fixation is widely exploited in agriculture, as are nitrogen fertilisers prepared for the last hundred years under extreme conditions of temperature and pressure.

However, despite all our efforts, the fundamental nature of the reactions involved at the heart of the biological process remain unknown. The actual and possible contributions of biological fixation of atmospheric N in tropical agriculture, which can play a crucial role in increasing the sustainability of yields with minimal external inputs, are described.

The process of biological N fixation and the organisms which are capable of fixing N in cropping systems of the tropics are described.
