Vegetable Cultivation 107 



Here are the fundamental rules of crop rotation : 



( 1 ) Crops of the same vegetable, or vegetables of 

 the same family (such as turnips and cabbage) 

 should not follow each other. 



(2) Vegetables that feed near the surface, like 

 corn, should follow deep-rooting crops. 



(3) Vines or leaf crops should follow root crops. 



(4) Quick-growing crops should follow those oc- 

 cupying the land all season. 



These are the principles which should determine 

 the rotations to be followed in individual cases. The 

 proper way to attend to this matter is when making 

 the planting plan (see page 18). You will then 

 have time to do it properly, and will need to give it 

 no further thought for a year. 



With the above suggestions in mind, and put to 

 use, it will not be difficult to give the crops men- 

 tioned in the following chapter those special atten- 

 tions which are needed to make them do their very 

 best.
