The results obtained woukl indicate tliat subsoilingr was injurious ratlier than 

 liolpful, since the four suhsoilod plots were lower in yield than any of tlie others. It 

 is impossible to feather umch information from the results on the other plots, as plough- 

 ing eight inches deep gave the hest returns while three inches deep was a close .second, 

 with the other plots showing no regular gradation in yield. 



DEPTH OF PLOUGHING SOD TO BE SOWN TO WIIE.VT. 



After the hay was cut, 1012, the land was ploughed August 3, double disced the 

 mnne day and again October 7. It was harrowed twice in the spring, and the wheat 

 was sown April 17, at the rate of 1§ bushels per acre. All plots came up May 3, headed 

 out .Tune 24. ripened August 5, were cut August 5, and threshed August 28. 



The experiment has not yet been in operation long enough to note the results of 

 the stubble ploughing following the sod.

The deep ploughing has the advantage in point of yield and, moreover, the grass 

 was sulidued better by the deep than by the shallow ploughing. 



SUMMER-FALLOW TREATMENT. 



With the exception of plots 11 and 13, which were ploughed May 17 and July 17 

 respectively, the land received the first ploughing of the fallow June 12 and 13, 1912. 

 The plots that were ploughed twice received their second ploughing September 4, 1912. 

 All except plot 17 were packed immediately after the first ploughing. Plots 1 to 9 

 were cultivated once in July and once in August, and harrowed aftdr each cultivation. 

 Plot 10 was well harrowed and sown to rape on June 17, which was pastured by pigs, 

 beginning August 13. Plot 11 was cultivated three times during the summer, plot 12 

 twice, and plot 13 only once. Plots 14 to 17 were cultivated twice (July and August). 

 All plots were harrowed after each cultivation. After harrowing in the spring, all 

 plots were sown to wheat April 16. All came up April 29. Plots 1 to 9 headed out 

 June 30 and plots 10 to 17 June 26. They were cut August 4 and threshed August 6.
