CHAPTER XXIV 

 THE ROTATION OF CROPS 



SYSTEMS OF CROPPING 



THERE are two methods or systems of cropping 

 the soil: 



The One Crop System, or the continuous crop- 

 ping of the soil year after year with one kind of 

 crop. 



The Rotation of Crops or the selection of a given 

 number of different crops and growing them in 

 regular order. 



The purpose of this chapter is to inquire into the 

 effect of these two systems of cropping : 



On the soil conditions necessary for the best 

 growth and development of the crops. 



On the market value of the crops. 



On the increase of or the protection from injur- 

 ious diseases and insects. 



On the distribution of labor throughout the year. 



On the caring for farm stock. 



On the providing for home supplies. 



This inquiry and the conclusion will be based on 

 the following facts learned in the foregoing chap- 

 ters.
