 COST OF PKODUCTION OF FIELD CEOPS. 



In calculating net profits from the rotations, some interesting figures have been 

 dbtained regarding the cost of producing the various crops grown. In explanation 

 of the rather high cost in some cases it may be explained that in 1913 some of the 

 fields did not yield quite up to the average production for previous years. Com and 

 turnips were the chief sutt'erers. The values used in computing these costs are given on 

 page 96 ai this report.

KOTATIOX OF CROPS. 



There is perhaps no single practice in farm management of more importance than 

 a systematic rotation of crops. It will help to maintain fertility, conserve soil moistu.re 

 and control weeds and yet withal it is a feature of farm work to which, as a rule very 

 little consideration is given. 



So many different combinations of crops are possible, that a test of all that -ug- 

 gested themselves to us was quite impracticable. The following three, chosen because 

 of the good results they have given in other sections of the country are now in opera- 

 tion. 



ROT.\TIOX " B" (five YE.VRS' DLKaTION). 



First year. — Eoots. Manured at rate of 25 tons per aci-e. 



Second year. — Grain. Seeded down with 10 pounds red cover, 2 pounds alsike and 

 6 pounds timothy per acre. 



Third year. — Clover hay. Ploughed in autumn. 



Fourth year. — Grain. Seeded down with 10 pounds red clover, 2 pounds alsike 

 and 6 pounds timothy per acre. 



Fifth year. — Clover hay. 



ROTATION "c'' (four YEARS' DURATION). 



First year. — Roots. Manured at rate of 20 tons per acre. 



Second year. — Grain. Seeded down^ with 10 pounds red clover, 2 pounds alsike 

 and 13 pounds timothy per acre. 

 Third year. — Clover hay. 

 Fourth year. — Pasture.
