FERTILIZERS AND AGRICULTURAL LIME 9 



Explanation of Tables of Analyses 



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

 a 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 

 and in that order. 



Mixtures Substantially Complying with the Guarantee. In addition to 

 the analysis of those fertilizers which meet their guarantees in every respect, this 

 table includes also those mixtures which have one or more elements below the 

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



Inferior Nitrogen. The presence of inferior forms of organic nitrogen is 

 indicated by footnotes. 



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

 those fertilizers which 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.
