the conversion of atmospheric nitrogen into the compounds by natural processes, such as lightning, and 4) biological nitrogen fixation (Vance 2001). The reduction of atmospheric nitrogen is a ...
Nitrogen is an essential component in the production of amino acids and nucleic acids -- both necessary for cell growth and function. Atmospheric nitrogen must first be converted, or 'fixed,' into a ...
but only a few taxa of bacteria have evolved the capacity to convert atmospheric dinitrogen gas, N 2, into assimilable forms of nitrogen, a process known as biological nitrogen fixation.
The nitrogen-15 isotopic technique is also used to quantify the amount of nitrogen fixed from the atmosphere through biological nitrogen fixation by leguminous crops. The carbon-13 isotope signature ...
nitrogen fixation (the conversion of atmospheric nitrogen to nitrogen compounds that can be used by plants and other organisms), and pollinator benefits. New research published in Agrosystems ...
Much of the competitiveness of autumn olive is due to its ability to fix atmospheric nitrogen in nutrient-poor soils ... Autumn olive engages in a symbiotic relationship with Frankia bacteria in root ...
