 cations are that it will soon take the lead." 



159. Observations on Rotation Tests at Brandon. 

 "From observing the results obtained from these rota- 

 tions and from farming conditions in Manitoba gener- 

 ally for a number of years, the following conclusions 

 among others have been reached : 



1. A good mixed farming rotation not only provides 

 for the future condition of the soil, but it gives a larger 

 per cent, profit than straight grain growing. 



2. Corn is an exceedingly valuable rotation crop, not 

 only for its fodder value, but because the grain crops 

 following it are the most profitable on the farm. 



3. It is impossible to control soil blowing and wild 

 oats by a straight grain and fallow system, no matter 

 how well you cultivate. Grasses control both satis- 

 factorily. 



4. The longer the start of mixed farming is postponed 

 the more difficult it is to start. 



5. The most profitable way to use grasses is in a short 

 rotation. Left in sod too long they become unpro- 

 ductive and hard to break up. 



6. There is no best rotation for all farms. Each indi- 

 vidual case must be studied by itself and a rotation de- 

 vised that will suit the kind of soil, the degree of weed 

 infestation, the rainfall that may be expected, the con- 

 venience to market of the farm, and the plans, oppor- 

 tunities and limitations of the man who supplies the 

 brains."
