70 PRACTICAL CORN CULTURE 
tural Experiment Station.), These results have been verified 
on thousands of farms throughout the Corn Belt. 
There are three common kinds of clover of general impor- 
tance to the farmer. They are, in the order of their im- 
portance: the common red or June clover, mammoth or 
sapling clover, and the Swedish or Alsike. The common red 
is the most extensively grown of these varieties. It will do 
well on most of the common prairie soils of the Corn Belt. 
It differs from the other two varieties in that it gives two 
crops in one season, either two crops of hay or a crop of 
hay and a crop of seed. 
Alsike will do well on any soil that common red clover 
will thrive on and in addition it will grow on soils that are 
too wet for the common. 
Mammoth clover is distinctly the clover for sandy and 
other poor soils. It will get along on soils too thin and too 
dry for either medium or Alsike to thrive on at all. This 
is the best clover for soiling purposes. If a soil is very sour 
and lacking in lime, it will not grow the clovers or other 
legumes until these conditions have been remedied. Two 
thousand pounds of limestone applied about once in every 
four years will correct the acidity in most soils and make it, 
not only possible, but easy to grow clovers and other legumes. 
The application of limestone to the soils of Southern Illinois 
has made possible the growing of clover on thousands of acres 
that were too acid before the application of lime was made. 
Clover has been grown successfully for years in central and 
northern Illinois without the application of limestone, al- 
though the soil would doubtless be benefited and the clover 
crop helped by its application. 
CULTURE 
We always sow clover in a nurse crop of wheat or oats. 
This is not only the profitable method, but it is best to have
