CRIMSON CLOVER IN CORN. 



A good and practical metliod of soil improvement and the production, 

 at the same time, of profitable corn crops, is to grow a crop of corn and 

 crimson clover each year, using good fertilization on the corn crop at 

 first. Crimson clover is sown in corn during the latter part of August 

 or early in September. A crop of crimson clover is obtained in this 

 way each year and very little difficulty is found in getting a stand of

crimson clover in the corn. The productiveness of the land can be 

 rapidly increased with this cropping provided sufficient amounts of 

 phosphoric acid be applied. 



CHEMICAL COMPOSITION OF PIEDMONT SOILS. 



Fourteen years ago the mapping of the soils of the State was started. 

 The maps, which are being made of the various counties, show the loca- 

 tion and extent of each type of soil. Thus far about 40 per cent of the 

 total land area of the State has been worked from which a large num- 

 ber of soil samples have been collected and analyzed. These analyses 

 are brought together on the following pages. They have been used in 

 connection with this report and these and other analyses will be used 

 in our further investigations of the soils and crops of the State. The 

 analyses show all of the Piedmont soils to be fairly well provided with 

 potash; poorly provided with phosphoric acid, with the exception of
