- Provide better weeds and insect control.
- Prevent soil erosion.
- Economize farm, labor, and cost.

- In the case of producing silage, such as maize or sorghum, which are very heavy and bulky, it may be advisable to grow these crops on the field near the silo pit.
- Weather conditions and other accidents may interfere with the rotation.

- Good rotation should include green manuring crops.
- Good rotation should include leguminous crops.
- Good rotation should include a profitable cash crop.
- Good rotation should include one tilled crop for eliminating weeds.
- Good rotation should include heavily manured crops to increase nutrient status in soil.
- Deep-rooted crops should be followed by shallow-rooted crops.
- Adjustment of the crop should be made according to irrigation facilities.
