Question

why do farmers grow leguminous plant and cereals alternatively?​

Answer 1

Answer:

farmers grow leguminous alternatively in thier fields. This is because a microorganism called Rhizobium lives in the roots of leguminous plants. these microorganism help in fixing nitrogen in the soil. they convert atmospheric nitrogen into nitrogen that can be used by the plants.

Answer 2

Answer:

The farmers grow leguminous plants and serials alternatively because the root nodules of leguminous plants (green gram, rice, black gram)

contain rhizobium bacteria in them. The rhizobium bacteria helps in conversion of atmospheric nitrogen into the form of nitrogen which plants can absorb (nitrates) . this is because the nitrogen abundantly present in the atmosphere cannot be taken by plants directly because it is not water soluble and the rhizobium bacteria makes them water soluble (nitrates) . so that the the field of the farmer does not lack in nitrogen the farmers grow leguminous plants and cerials alternatively
