Why do farmers rotate crops in the field?

The whims of nature are always changing, which means farming practices must also adapt. Crop rotation involves alternating the crop that’s planted in a field from one season to the next. If you’re wondering why farmers rotate crops in the field, we’ll explain the answer in detail.

Controls pests and plant diseases

One of the biggest benefits of rotating crops is the ability to keep pests and diseases at bay. Nature thrives on change, which is why this strategy works.

Pests, such as corn rootworms, eat the roots of corn and hatch larvae in the soil. Since they only eat corn plants, the population will multiply if a farmer plants corn several years in a row.

Planting a different crop, like soybeans, will eliminate the food source for the corn rootworm, and the population will die off. Crop diversity will create a more resilient farm by preventing these pest populations from growing.

Improves soil quality and nutrients

Planting the same crop year after year will use the same nutrients and threaten the soil quality. For example, corn depletes nitrogen levels in the soil, but soybeans replenish it. Introducing variety to the planting schedule will improve the quality of the land.

Crop rotation maintains soil nutrients, which is why one of the most popular strategies to boost corn yield is to alternate crops. Rotating crops also prevents moisture loss and erosion. Planting crops with varying root depths strengthens the soil at all levels.

Lowers dependence on fertilizers and pesticides

Because crop rotation naturally improves soil health, farmers don’t have to depend as much on fertilizers and pesticides. Less reliance on chemicals is not only good for the environment, but it also cuts down on operational costs for farmers. Farmers won’t have to spend as much money on supplies or spend as much time spreading chemicals.

Prevents loss of income

Without the practice of crop rotation, farmers would need to leave a field fallow or skip planting for a season. A crop-free field gives the soil time to rest and rebuild its nutrients. That said, an empty field during the growing season won’t turn a profit.

By planting a field with a different crop instead of leaving it empty, farmers can replenish the soil quality without letting valuable acreage lie empty.

Farmers rotate crops in the field because it provides many benefits. It’s an effective way to make the most of the growing season and valuable acreage.
