    Repeated growing of the same crop depletes the soil of specific nutrients. But rotating different crops in the same piece of land in same year replenishes the soil naturally. Generally, the leguminous crops are alternated with other crops because the legumes have nitrogen fixing bacteria in their roots which converts atmospheric nitrogen into nitrates thus increasing nitrogen strength in the soil.
