Question

what are leguminous crops?how do leguminous crop help the farmers

Answer 1

These plants have legumes or small spaces in their roots where a special kind of bacteria live. These Bacteria are called nitrogen-fixing bacteria. Plants need nitrogen to make amino acids which make proteins which make the cells which is important for growth, but plants cannot use the nitrogen in the air(they are unable to). So they absorb nitrate ions(NO3) from the soil as a source of nitrogen. If you read about the nitrogen cycle(a very simple concept) you will realise there is nitrogen fixing bacteria present in the soil. These bacteria 'breathe' in nitrogen and uses energy to transform the nitrogen to a nitrate ion.


leguminous plants are very important for farmersbecause it helps the plants in nitrogen fixation since plants cannot absorb nitrogen directly from the atmosphere. farmers while harvesting make sure that they leave the roots of these leguminous plants in the soil as it helps in nitrogen fixation.
