The economic and environmental costs of the heavy use of chemical Nitrogen fertilizers in agriculture are a global concern. Sustainability considerations mandate that alternatives to N fertilizers must be urgently sought. 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. Symbiotic systems such as that of legumes and Rhizobium can be a major source of N in most cropping systems and that of Azolla and Anabaena can be of particular value to flooded rice crop. Nitrogen fixation by associative and free-living microorganisms can also be important. However, scientific and sociocultural constraints limit the utilization of BNF systems in agriculture. While several environmental factors that affect BNF have been studied, uncertainties still remain on how organisms respond to a given situation. In the case of legumes, ecological models that predict the likelihood and the magnitude of response to rhizobial inoculation are now becoming available

When the program ran, from its start year to the latest document year. A hatched bar means the start is our estimate.
Axis: award years, end from years in documents. The start year comes from award fiscal year; the end is the latest document year, so the program may have run longer.

DEC topic and subject tags. They describe the documents, not what the program was. Each tag opens its evidence in the drawer.
Programs worth reading next, by topic, implementer, country and years. Similar by facets (topic, implementer, country, years) and, when available, description. It says the programs look alike, not how they are related in time. Source: catalog facets
