SOIL CULTURAL EXPERIMENTS. 



Soil cultural experiments inaugurated in 1911 for the purpose of investigating 

 some of our more important problems in soil cultivation have been carefully carried 

 out. The results do not yet supply much decisiv:- information and little comment is 

 therefore made in connection with the various experiments recorded. 



DEPTH OF PLOUGHING WHEAT STUBBLK TO BE SOWN TO OATS. 



The land was ploughed and packed in October, 1912. In the spring it was har- 

 rowed and the seed sown ISlay 7, at the rate of Si bushels per acre. The oats came up 

 on all plots May 23, headed out July 9, ripened August 14, were cut August 14, and 

 threshed September 2.

There is a slight advantage in favour of ploughing 5 inches deep, but the differ- 

 ence is hardly great enough to be regarded as conclusive. 



depth of ploughing summer-fallow to be sown to wheat. 



The summer-fallow was ploughed in June, 1912, packed immediately, cultivated 

 twice afterwards during the season, and harrowed after each packing or cultivating. 

 In the spring it was cultivated and harrowed again, and the wheat was sown April 25, 

 at the rate of 1| bushels per acre. All plots came up May 14, headed out July 6, 

 ripened August 12, were cut August 13 and threshed August 28.
