THE PROBLEM OF TILLAGE 



but it also means that the soil is robbed 

 of its much needed moisture, which too 

 often resvdts in crop failure.. In dry- 

 farming light seeding almost always 

 gives the heaviest yields : and the old cus- 

 tom of sowing 1^ to 2 bushels of grain 

 to the acre is altogether wrong. In a 

 recent experiment carried out by the 

 Montana Experiment Station with 

 spring wheat, oats, and barley, it was 

 found that three pecks of seed (45 lbs.) 

 gave better results than larger quantities. 

 Again, in Utah, the heaviest yields of 

 grain have been obtained with from two 

 to four pecks (30-60 lbs.) of seed, while 

 Campbell recommends the following 

 amounts for well-fitted summer-tilled 

 fields: winter wheat 18 to 20 pounds; 

 spring wheat 20 to 25 pounds; barley 35 

 to 40 pounds per acre. Further, Cooke of 

 Wyoming writes : "It is a recognized fact 

 that we have been making the. very
