Depth of Ploughing Wheat Stubble to be sown to Oats. 



While, it is possible that the above tests have not been running long enough t j 

 give decisive data, this season's work would seem to indicate that while deep plough- 

 ing did not always give noticeable increases the first season, it did increase the 

 yield the second season. The ploughing of summer-fallow should be at least 6 

 inches deep and fall ploughing for oats 5 inches. 



DEPTH OF PLOUGHING SOD. 



This experiment is being conducted in a four-year rotation of: — 



First y&ar: — Wheat. 



Second year. — Oats. Seeded down. 



Third year. — Hay. 



Fourth year. — Hay. 



The sod was ploughed 3, 4 and 5 inches deep in preparation for wheat, aiid the 

 wheat stubble, 3, 4, 5 and 6 inches deep in preparation for oats.
