FARM MANAGEMENT AND CROP ROTATION 



the farming business, the second year the fields were cropped as is 

 shown in Figure 216. Note that the timothy sods were plowed up 

 and field number one was made two acres larger. 



The third year the fields were rearranged as is shown in Figure 

 217 — a fixed three-year rotation being established. 



The rotation planned and soil improvements to be made are 

 indicated in the following rotation chart:

Problem IL — ^Plan definite cropping plans for an eighty-acre 

 farm which is intended for dairying. 



Just seventy-four acres are available for raising the main crops 

 — ^hay, grain and corn. 



Yields of crops would support, at the start, at least fifteen cows, 

 a few young stock, four horses and some pigs. 



Summer feeding to be silage, soiling crops, grain and whatever 

 pasturage may become available. The farmer expects to buy 

 whatever additional feeds are required. 



Twelve acres of alfalfa, twelve to thirteen acres of clover, 

 twenty-four to twenty-five acres of corn, and twenty-four to 

 twenty-five acres of grain are to be grown annually. 



Figure 218 shows the existing conditions as regards the fields, 

 permanent fences, hay fields, etc. 



The farm consists entirely of silt loam. Fields numbers two 

 and three are especially well adapted to alfalfa. Field four (a) is 

 the poorest field.
