fallow practice has also reduced the quality of the 

 grain, as shown by the analyses of a large number 

 of samples of early and late seeded grain. 



"During recent years, mainly as a result of 

 the reduction in size of some grain farms, and the 

 educational efforts conducted by the university 

 of California throughout the state, there has been 

 an increase of the depth of plowing on the part of 

 some farmers, but in general the same careless 

 methods of culture still hold. 



"To summarize, the general effect of the past 

 and present methods has been the development 

 of a poor physical condition of the land, largely 

 a result of the depletion of the humus, until the 

 soil refuses to produce profitable yields of the 

 commonly grown varieties of wheat under the 

 old system of farming." 



CULTURE METHODS IN WASHINGTON AND 

 OREGON 



The culture methods practiced in Washington 

 and Oregon are perhaps little if any better than 

 those in California, but the newer lands in these 

 states have not yet begun to show the decrease 

 in yield which will surely follow continuous grain 

 growing. The experiment stations and some of 

 the farmers are trying to solve the problems of 

 restoring the humus and soil nitrogen and thus 

 maintain the soil fertility. Experiments indicate 

 that this may be accomplished by green manuring, 

 rotation of crops, and deeper tillage; but it is a 

 difficult matter to rotate crops in these exclusively 

 grain raising areas, also the crops which are hardy
