ROTATION OF CEOPS. 



In the spring of 1899 arrangements were made for a series of rotation plots, the 

 principal object being the maintenance of the fertility of the soil by the ploughing 

 under of a leguminous crop every third year instead of the usual summer-fallow. 



As the first field selected for this purpose was flooded in 1902 and 1904, it was con- 

 sidered unsuitable, and a new location was selected last year. 



The Red Clover was sown at the rate of 12 lbs. -per acre and mixed clovers in the 

 proportion of 8 of Alfalfa and 6 lbs. of Alsike per acre. These leguminous plants were 

 ploughed under when they reachd their fullest development. 



The grains used in this test were Red Fife wheat. Banner oats, Mensury barley 

 and Gregory pease. The size of the plots was one-twentieth of an acre. 



ROTATION TEST. 



The order of rotation is as follows : — 



16— 20J
