sists 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 soil does not re¬ 
spond 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 better 
adapted to potato culture than are the sand soils. It is there¬ 
fore 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 graz¬ 
ing, and are not well adapted to any of the grasses. This sys¬ 
tem would make possible keeping more stock, and with the in¬ 
creased supply of manure the fertility of the land could be more 
readily maintained.
