While most vegetation types must extract most of their nutrients from fertile soil, mesquites and similar plants receive additional nitrogen from symbiotic bacteria, which enzymatically fix ...

Associative and symbiotic nitrogen-fixing microorganisms obtain these compounds from their host plants’ rhizospheres (National Research Council 1994, Hubbell & Kidder 2009). Industries use the ...

Atmospheric nitrogen must first be converted, or 'fixed,' into a form that can be used by plants, often as ammonia. There are only two ways of fixing nitrogen, one industrial and one biological.
