How do bacteria achieve nitrogen fixation
WebApr 8, 2024 · Dave Edwards reckons farmers should embrace new ways of making nitrogen 'work' for them. Prior to the 1960s, nitrogen was used at relatively low rates in agriculture – crop nitrogen uptake was mainly dependant on manure applications, biological nitrogen fixation and nitrogen supply by mineralisation of the soil organic matter. WebJul 26, 2013 · The Importance and Function of Nitrogen-Fixing Microbes. All organisms on Earth require nitrogen to survive, but most cannot use nitrogen unless it is combined with other elements. These compounds are formed by the process known as nitrogen fixation, which can only be carried out in nature with the help of microorganisms. In agriculture ...
