quite consistent. In 1914 the subsoiled ground apparently lacked 
water to mature its crop. Greater differences have been manifested 
in the yields of grain than in those of stover.

Particularly in the production of grain, spring plowing has been 
markedly better than fall plowing. After both fall and spring plow- 
ing the yield has been better following small grain than following corn. 
Subsoiling for this crop has been done only on ground continuously 
cropped to corn. The yield by this method in 1914 was the lowest 
of any except by the fall plowing of similar ground. 
Slightly higher yields than by any other method have been obtained 
by listing on ground continuously cropped to corn. Corn following 
summer tillage has been productive of crops practically equal to those 
on hsted corn ground. On the whole, there is little choice to be made 
from so short a record between the yields on summer-tilled land, listed 
corn ground, and spring-plowed grain stubble. 
Profits ranging from 87 cents (by fall plowing after corn and $1.47 
by summer tillage) to $6.28 (by spring plowing after small grains 
and $7.75 by listing after corn) have been realized. All methods 
except fall plowing after corn, subsoiling after corn, and summer 
tillage have shown a profit from the grain crop alone. 
WILLISTON FIELD STATION. 
The results of five years at Wilhston, N. Dak., are available for 
study and are shown in Table VII. In only two of these years has 
mature corn been produced. In each of these years the yield has 
been very good. The yields of stover in 1912 are exceptionally high —
