and rainfall, no definite standard rotation can be pro- 

 posed that will be applicable to all conditions. 



326. Example of Rotation. In dealing with the 

 subject of rotations it is best to take actual problems 

 as they present themselves and plan rotations that 

 will best meet all of the conditions. For example, a 

 farm of 160 acres is to be rotated with the main ob- 

 ject of producing fodder for live stock, and a small 

 amount of grain for sale. To meet these require- 

 ments the rotation outlined on pages 238 and 240 is 

 given. 83 



The farm is divided into eight fields of 20 acres 

 each ; seven fields are brought under the rotation, 

 while one field is left free for miscellaneous purposes. 

 Each year there are produced 20 acres of corn, 20 

 acres of timothy and clover hay, 10 acres each of 

 wheat and flax, 20 acres of barley, and five acres each 

 of corn fodder, rye, peas, and potatoes, while 20 acres 

 are reserved for pasture. The main income is de- 

 rived from the sale of live stock and dairy products.
