Why are leguminous crops desirable in crop rotation?

उत्तर
Leguminous crops are desirable in crop rotation because they maintain the supply of nitrogen in the crop fields. These crops are alternated with others so as to minimise the need of nitrogenous fertilisers. Nitrogen fixers in leguminous crops fix the atmospheric nitrogen and makes it available to the crop plants. These are mostly used in the crop fields where nitrogen supply is less.
