Answer:
Rabi crop wheat and kharif crop - soyabean or groundnut can be plant for crop rotation. Leguminous crops replenish nitrogen. The leguminous plants have some swollen structures on the surface of their roots.These are called root nodules. The bacteria residing in the root nodules convert atmospheric nitrogen into soluble nitrogenous compounds. This increases the fertility of soil
