FERTILIZERS AND AGRICULTURAL LIME 



EXPLANATION OF TABLE OF ANALYSES 



Guarantee. The plant food guarantee or the grade of each fertilizer is made 

 I part of the trade name under the heading "Name of Manufacturer and Brand" 

 and is expressed as nitrogen, available phosphoric acid, and water soluble potash 

 in that order. 



Mixtures Substantially Complying with the Guarantee. In addition to those 

 fertilizers that meet their guarantees in every respect, this table includes also a 

 list of those mixtures that have one or more elements below the guaranteed per- 

 centage but have a shortage of less than $1 per ton. 



This table, in addition to the data nientioned in the next paragraph, contains 

 only results of analytical tests pertaining to the average amount of water in- 

 soluble nitrogen present in each brand, since this information is of value to 

 tobacco growers and other users of fertilizers containing a high percentage of 

 this form of nitrogen. 



Potash Forms. Tests for chlorine are made only on tobacco mixtures and on 

 those fertilizers that carry a guarantee of potash in forms other than muriate. 

 When the amount of chlorine present in any brand exceeds the tolerance allowed 

 for that brand, this fact is indicated by a footnote. 



Mixtures Showing a Commercial Shortage of $1 or More per Ton 



a Potash in forms other than muriate. See table of "Mixtures Substantially Complying with 

 Guarantees."
