Shifting of Crops
Crops must not be grown twice in rotation on the same ground. Peas and beans should be the crop after any of the roots, such as potatoes, carrots, and parsnips. Cabbages, and plants of that kind, may be sown and grown intermediately. The best rotation of crops will be found in any gardening book on the subject, and this the young gardener should make a subject of some study.
