lo Mar., 1911.] NortJicni Grain Experimental Fields. 



139 



The owner of each seven-year experimental field of 10 acres has under- 

 taken to conduct continuous experiments over that time. The agreement 

 terminates this coming season. The seed and manure are provided free 

 by the Department who.se Field Officers sow the crops and supervise the 

 harvesting operations. The fields containing 10 acres are divided into 

 four separate .sections known as : — 



A. Not subsoiled. C. Wheat and Oat varieties. 



B. Subsoiled. D. Fodder crops. 



The manurial dressings on A and B are similar, the object being to ascer- 

 tain if subsoiling will produce an increased yield sufficient to justify the 

 extra cost of deeper cultivation. The farmer conducting the experiments 

 receives a cash payment of ^15 per vear and two- thirds of the resultant 

 crop, besides having the right to graze the area which has been securely 

 fenced by the Department. This grazing right is of value during certain 

 years, such as when rape is grown on the stubble in the rotation which 

 .serves the double purpose of fertilizing the land and providing succulent 

 food for la.mb-raising.
