Question

how do leguminious plants fix nitrogen?​

Answer 1

Answer:

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. These special bacteria stimulate the growth of nodules on the roots of leguminous plants.

Answer 2

bacteria called rhizobium convert nitrogen from atmosphere into nitrates and nitrites which are used by plants and animals. When these plants and animals die these bacteria and rhizobium converts nitrates and nitrites into atmospheric nitrogen again. This cycle continues.
