might exhaust the moisture to that degree that 

 winter killing might be the result. 



Plenty of moisture in the soil in the spring to 

 draw the frost from the roots in late winter or 

 early spring thawing and freezing is proof against, 

 so-called, winter killing which in reality is spring 

 killing. 



SPRING WHEAT 



In seeding spring wheat, about one-third more 

 wheat is necessary than for fall wheat in fairly 

 early seeding, and possibly one-half more seed in 

 case of late seeding on well fitted land. 



Much depends on the physical condition of the 

 seed and root bed and whether the land was fall 

 or spring plowed, the real point being whether 

 the wheat stools liberally or not, which is governed 

 by the degree of care in fitting the seed bed and 

 the available moisture and fertility.

DISKING AFTER THE HARVESTER 



Cut No. 21 shows a very economical way of 

 harvesting wheat and double disking the land 

 at the same time with a tandem or double disk 

 harrow. No matter what crop is being cut, this 

 disking we have always found of great value.
