TENTH ANNUAL YEAR BOOK— PART X

ACEEAGE OF CEOPS EEQUIBED FOE FEED. 



With the data given in the last column of Table 4, which shows the 

 acreage of each crop grown for feed required for the support of one cow 

 and corresponding young, it will be easy to calculate the acreage required 

 for the whole herd. Thus, in the case of corn silage, if 0.561 acre is re- 

 quired for 1 cow and young, 23 cows will require 12.9 acres. 



The acreage thus obtained for all the crops grown for the herd of 23 

 cows, as well as the acreage of the different crops required for the fixed 

 stock on the place, as shown on above are given in the following table:

From the last column in the above table it will be seen that it will be 

 necessary to grow on the farm each year for the herd and fixed stock 

 13.28 acres of corn for silage and 13.48 acres of corn for grain, or 26.76 

 acres of corn in all, 14.15 acres of oats, 25.4 acres of clover hay, and 8.63 

 acres of pasture. 



ROTATIO^^ to be FOLLOWED. 



For practical purposes of rotation it may be assumed that the acre- 

 ages required for the different crops in round numbers are as follows: 

 Corn, 27 acres; oats, 15 acres; hay, 25 acres; pasture, 9 acres; total, 76 

 acres. While on a dairy farm, where an abundance of stable manure is 

 available, systematic rotation is not so essential as on a grain farm, yet 

 rotation is always good farm practice. In the present instance it will be 

 easy to fit the crops required to a four-year-rotation. For this purpose 

 the 76 acres may be divided into 4 fields of 19 acres each and the follow- 

 ing cropping plan adopted on each field: 



First year, 19 acres of corn, well manured. 



Second year, 19 acres of oats, 4 acres cut for hay, whole field seeded 

 down. 



Third year, 19 acres of hay. 



Fourth year, 19 acres — 9 of pasture, 2 of hay and 8 of corn. 



This scheme would require movable fencing for the 9-acre pasture.
