Crop rotation is the practice of growing, different crops in the same piece of land, and moving them around in a planned sequence. For instance, monocots and dicots should be rotated after every season.
It helps build soil fertility, improve soil structure, and help control pests and disease.
Examples of the sequences
Rotate maize and beans
Brassicas and onions
Crops of the same family should not be rotated; this is because they share common traits e.g. Root length, pests, and diseases, and thus rotating them is not gainful.
