EXPERIMENTS IN UTAH. 



11 



The next station to take up this study was Illinois. Under the 

 direction of Morrow and Hunt the work was begun in 1888 and con- 

 tinued until 1893; it was taken up again in 1896, thus covering seven 

 years. 



In 1889 and 1890 the Missouri Agricultural Experiment Station 

 made investigations on the depth of cultivation and included plats 

 that were weeded but not cultivated. These experiments included 

 the effect of the treatments on soil moisture for the year 1890. This 

 work was started by Sanborn, who, upon his retirement to become 

 director at the Utah station, started the same kind of work at the 

 latter place. 



In 1898 and 1899 the South Carolina station made tests of various 

 methods of planting and depths of cultivation, and included a plat 

 that was weeded but not cultivated. 



The results of all these experiments, with the exception of those in 

 Utah, are shown in Table I.

EXPERIMENTS IN UTAH. 



Table II shows the results of seven years' work covering experi- 

 ments on corn cultivation made at the Utah Agricultural Experi- 

 ment Station, as recorded in Bulletin No. 66 of that station. As 

 these experiments were made under irrigation conditions, the data are 

 not included in the discussions of the other early experiments or in 

 the resume on page 24. It is apparent that the "no tillage" treat-
