Biological Nitrogen Fixation (BNF)

Biological Nitrogen Fixation - BNF1 refers to the absorption of elemental atmospheric nitrogen, to naturally combine it into soluble nutrient compounds.

"Fixed nitrogen is probably the main plant nutrient that limits agricultural production worldwide. For most developed countries this limitation can be alleviated by the use of nitrogenous fertilizers. The increased cost of fertilizer nitrogen, concern about nitrates in water supplies, and the limited availability of fertilizer in developing countries are major factors influencing a desire to obtain more fixation by biological means 2. It is likely that nearly all plant species benefit from nitrogen fixation by bacteria associated with their roots. How much they benefit appears to be related directly to the degree of complexity of the interaction between the plant and nitrogen-fixing bacteria. For example, some leguminous plants, which have root nodules containing rhizobia, can fix more than 100kg Nitrogen per hectare per annum, whereas some grasses which have Nitrogen-fixing bacteria associated with their roots may support fixation of 10kg N per hectare per annum"3.
