Question

Why is leguminous crop rotation used in agriculture?

Answer 1

Leguminous crops are rotationally used in agriculture

Example: pea

Because the Rhizobium Bacteria present in the root nodules of the plant will fix the atmospheric nitrogen into ammonia by combining nitrogen and hydrogen by using Nitrogenase enzyme

The ammonia form only utilised by the plants for the synthesis of nutrients but not the nitrogen form

This is a symbiotic relationship where bacteria will be supplied with carbon energy source where plants get amino acids for their metabolism
