rotate crops
They rotate their crops to utilize bacteria to increase nitrogen in the soil. because diffrent crops take up diffrent nutrients so they are rotated to ensure they have a good supply of the right nutrients
Farmers rotate crops such as beans, peas, and peanuts with other crops such as corn, wheat, and cotton as a natural way to maintain soil nutrition. Proper crop rotation can reduce the need for adding other fertilizers.
legumes contain high level of nitrogen which are leeched into the soil. this allows the farmer to then plant crops such as corn that use that nitrogen

There are many different farming techniques. Most farmers rotate their crops from year to year so the nutrients in the soil do not get depleted. Some farmers also plant two or more crops together.
No. Farmers rotate crops (which means planting a different crop each year) in order to keep the soil fertile, full of nitrogen, and to help mitigate the build-up of pathogens.
If crops are not rotated, and if the field does not lie fallow occasionally, the topsoil will erode, and not be able to produce crops. That is why Mesopotamia, what was once the Fertile Crescent, is now a desert. That is why there was a Dust Bowl in the Midwest in the '30s.

Farmers diversified their crops
After farming an area for a while, the soil became depleted of nitrogen and became unsuitable for growing. This was solved with crop rotation that meant that farmers would also plant crops that would replenish the nitrogen, like legumes.
