The correct answer is: D) All of the above
Crop rotation is a system of growing different types of crops in the same area in sequential seasons. It helps to improve soil fertility, reduce pest and disease incidence, and break weed cycles.
Managing soil fertility
Crop rotation helps to maintain soil fertility by preventing the build-up of pests, diseases, and weeds. It also helps to improve the structure of the soil and the availability of nutrients.
Reducing pest and disease incidence
Crop rotation helps to reduce pest and disease incidence by disrupting the life cycles of pests and diseases. When the same crop is grown in the same area year after year, pests and diseases can build up to high levels. Crop rotation helps to break this cycle by planting different crops each year.
Breaking weed cycles
Crop rotation helps to break weed cycles by planting different crops each year. Some weeds are more likely to grow in certain types of crops. By planting different crops each year, you can prevent weeds from becoming established.
In addition to these benefits, crop rotation can also help to improve crop yields and reduce the need for pesticides and herbicides.
