Crops are rotated for several reasons. One is that different crops have different nutrient requirements and sometimes when you plant a different crop it allows you to reduce the amount of fertilizer you need to apply. For instance legumes fix their own nitrogen and actually can put some nitrogen back into the soil. Another reason is to manage insect and disease pressures. Disease spores and insects overwinter in soil and crop residue left over. Certain crops are susceptible to certain disease and insect damage so when we change the crop we remove those pests' food source. A third benefit has to do with the crop's root system. Different root systems can reach different levels of the soil profile and therefore they can 'pull up' some nutrients that are deeper in soil profile, maximizing soil nutrients. One final benefit is that crop rotation can often maximize the economic potential of a piece of land while at the same time reducing soil erosion because some crops can be grown at different times of the year, leaving the land fallow for far shorter periods of time.
The crop rotation method was developed to rotate crops that depleted the soil of natural nutrients with crops that redeposits those nutrients back into the soil. Usually crops are rotated season to season.
Crop rotation is important because certain crops deplete nutrients from the soil and overplanting these crops can make the soil unable to support future crops. By rotating crops, this allows nutrients to replenish in the soil naturally, minimizing the need for artificial fertilizers.

Different crops use different nutrients from the soil. Crop rotation means that specific nutrients have time to replenish themselves over successive seasons.

Crop rotation can help maintain soil fertility by reducing the depletion of specific nutrients in the soil. Different crops have varying nutrient requirements, so rotating crops helps prevent the build-up of pests and diseases that can impact soil health. Additionally, certain crops can fix nitrogen in the soil, benefiting subsequent crops in the rotation.
Land rotation refers to the practice of alternating the use of a piece of land between different types of crops or activities over time, such as switching between agricultural production and fallow periods. Crop rotation, on the other hand, specifically involves the systematic planting of different crops in a particular sequence on the same piece of land to improve soil health, prevent pests and diseases, and increase crop yield. In essence, land rotation is a broader concept that encompasses various land uses, while crop rotation is a specific agricultural technique aimed at sustainable farming practices.
Rotation is when you turn an object.
Rotation of crops allows the land to replenish its nutrients and allows the land to be of use for a longer period of time instead of being used up completely and damaged beyond repair.
