INSPECTION OF COMMERCIAL FERTILIZERS 



37 



Nitrogen Compounds 



The chemicals and unmixed materials under this heading are valued chiefly 

 for the nitrogen which they contain. Some of them, however, contain more than 

 this one element; the nitrate of potash containing potash; the calcium nitrate 

 and cyanamid containing lime; and the organic vegetable substances containing 

 small quantities of phosphoric acid and potash, as will be noticed by a reference 

 to the summary table on the previous page. 



Brands showing a commercial shortage of one dollar or more per ton are listed 

 by themselves, serious deficiencies being emphasized by boldface type.
