Of these 400 acres, 100 acres would be fallowed each summer and 300 

 acres would be seeded to wheat. One-third of the wheat grown would be 

 sown on fallow, one-third sown on early listed or plowed ground and the 

 other one-third sown on plowed or disced ground, or stubbled in, depending 

 upon the character of the soil and season. Such a system of summer- 

 fallowing would divide the work and distribute it throughout the year and 

 at the same time would not reduce, but would undoubtedly increase the 

 productiveness of the land over a system of continuous cropping. 



The Summer-Fallow in Rotation of Crfops. 



The most profitable way of using the summer-fallow is in a rotation 

 of crops. It is a demonstrated fact that the most successful farmers in 

 central and western Kansas are those who are following a diversified 

 system of farming and growing feed crops for stock together with wheat. 

 The sweet sorghums, kafir, feterita, and milo are the most profitable feed 

 crops. To produce the maximum yield of wheat and kafir or sorghum 

 under such conditions, the crops must be grown in rotation and not grown 

 on the same land continuously. s 



Wheat will not, under normal conditions, make a profitable crop when 

 sown on sorghum or kafir stubble. Kafir or sorghum grow late in the fall 

 and exhaust the soil so completely of moisture and available plant foo] 

 that wheat sown upon such ground is usually a failure. Therefore, in plan- 

 ning a rotation of crops for such conditions, summer fallowing is indis- 

 pensable. 



The accompanying table shows a three-year rotation on three fields 

 where wheat and kafir are grown and the ground summer-fallowed one 

 year in three.

Where wheat is the most important crop and where there is sufficient 

 moisture to justify it, a 4-year rotation of wheat — two years, sorghum or 

 kafir — one year, summer fallow — one year, can be followed. When kafir or 

 sorghum is the most important crop, a 4-year rotation of two years of 

 kafir or sorghum, one year of summer fallow, and one year of wheat can 

 be used. In either case, the ground is summer-fallowed after kafir or
