CROP ROTATION CHART

4. Rearrange the fields oi combine small fields into larger units, 

 whenever possible, to facilitate farm management. (When no 

 special soil problems or conditions are to be met, the fields may be 

 learranged at once and the pioper rotations adopted.) 



Case D. — ^Rotations in truck farming, with soil problems. — 

 Proceed as in Case C. 



Crop Rotation Chart. — In planning rotations on farms having 

 soil and crop problems which must necessarily complicate the 

 cropping plans, a rotation chart is of great help. For example, the 

 cropped portion of a farm, excluding permanent pasture, consists 

 of sixty acres, which are divided into six ten-acre units. Twenty 

 acres each of corn, oats and hay (ten of alfalfa) are to be 

 grown annually. 



Fields I and IV are especially well adapted to alfalfa. 



Fields II; III and VI require improvement, hence a three-year 

 rotation is planned for each of these three fields (p. 273). 



Fields IV and V, and also I, are highly productive and hence 

 can well take care of irregularities in the cropping plans, as is shown 

 in the following outline:
