How is nitrogen fixation regulated
WebNitrogen fixation. Two spoonfuls of 'black magic powder' can double the yield of an average African field used for growing leguminous plants. Legume crops such as beans, peanuts and soy can fix nitrogen from the air, and flourish on nitrogen- deficient soils. To do so, they need help from Rhizobium bacteria.
