GROUP OF SANDY SOILS

consists of rye, clover, and corn. If the fertility is extremely 
low, it will be advisable to plow under the entire clover crop. 
If the fertility is fair the first crop may be cut for hay and the 
second plowed under. While potatoes are quite extensively 
grown on these extremely sandy soils this crop is not as well 
adapted to the sand soils as to sandy loam types. It has been 
shown by actual field tests that the yields of corn, for example, 
can be more readily increased on the sand soil than can the 
yield of potatoes. The potato when grown on sand soils does 
not respond to methods of soil improvement as readily as when 
grown on soils which contain somewhat more silt and clay. The 
sandy loams and fine sands and fine sandy loams are much bet¬ 
ter adapted to potato culture than are the sand soils. It is 
therefore advisable to reduce, where possible, the acreage of 
potatoes on sand soils. 
With an increased acreage of corn it will be possible to put 
up enough silage so silage may be used for summer feeding. 
With this practice less pasture will be required, and this again 
will be desirable since the sand soils do not supply good grazing, 
and are not well adapted to any of the grasses. This system 
would make possible keeping more stock, and with the increased 
supply of manure the fertility of the land could be more readily 
maintained. 
When properly managed alfalfa can be successfully grown 
on very sandy soils. For further information on the manage¬ 
ment of soils, see Bui. 299, Wis. Exp. Sta.
