ROTATION OF CROPS. 



ROTATIOX "a" (gRAIX COXTlNUOUSIiV) . 



On this area, which compri.ses 1 acre, wheat is the grain crop used. The land 

 is given good cultivation. No return of manure or fertilizer is made to this area. 

 By carrying on this work over h series of years information as to the power of our 

 soil to grow wheat continuously will be obtained. 



ROTATION "c" (TIIREK VKAK.s' UUII-VTIOn). 



Fhst year. — Summer-fallow. 

 Second year. — Wheat. 

 T]iird yew. — Wheat. 



Rotation *' C " is a straight grain-growing rotation commonly used where it is 

 desired to make wheat the main crop. When the cultunal operations are timely, 

 and thoroughly performed, this rotation is fairly satisfactory for a time at least. 

 l'>y its use the land may be kept clean and in a good state of tilth. Further, the 

 growing of two crops with the use of three yoars' rainfall ensure-^ to the growing 

 crop a suH!cient amount of mojisturc to produce a fair yield of wheat. There is the 

 danger in this rotation that in time the soil will become deficient in fibre and humus, 

 that crop yields will show a falling off, and that the single crop may meet with 

 :ome disaster from inclement weather before maturity. The net profit per acre 

 from rotation " C " in 1913 was $4.78.
