Winnebago sandy loam. — A brown to slightly reddish sandy to 

 heavy sandy loam, often containing considerable silt. The sand is 

 coarse to medium. Varies considerably in character and depth, 

 but averages about 10 inches. The subsoil is about the same in 

 texture, but more often of a reddish-brown color. From 18 to 36 

 inches it is underlain by a gravelly till. The surface is rolling 

 and uneven. Underdrainage is good. It is a very good corn soil, 

 although the average yield is not over 30 bushels per acre. Oats 

 are extensively grown, giving about the same yield as corn. 

 Clover, timothy, and rye also do well.
