An ideal rotation should include a balance of different crops. The main aim of a rotation is to provide a profitable sequence that breaks the pest and disease cycle, improves weed control, prevents soil erosion and improves the nutrient cycle and soil condition.
The choice of crops used in a rotation affects many aspects of farming including, the time of sowing, the type and timing of the cultivation and the range of herbicides available for use. Some crops compete with weeds better than others
