48 CONTROL SERIES No. 105 



The analysis or grade of a fertilizer should be included with its brand name, 

 and so used by the manufacturer on sacks and in printed literature and by the 

 control official in his reports and publications. 



Cyanamide and urea nitrogen is synthetic non-protein organic nitrogen. 



A fertilizer formula shall express the quantity and grade of the crude stock 

 materials used in making a fertilizer mixture. For example: 800 pounds of sixteen 

 per cent superphosphate, 800 pounds of tankage (7.40 nitrogen and 9.15 total 

 phosphoric acid), and 400 pounds of sulfate of potash-magnesia (twenty-six per 

 cent (26%) potash). 



Finely ground in the definition of basic phosphate slag shall refer to actual 

 size of particles as determined by the use of standard sieves, as follows: seventy 

 per cent (70%) or more shall pass a 100-, and ninety per cent (90%) or more shall 

 pass a 50-mesh sieve. 



The term "lime" shall not be used in the registration, labelling, or guaranteeing 

 of fertilizers or fertilizing materials unless the lime is in a form or forms to neutral- 

 ize soil acidity. 



The weights appearing on packages of fertilizer, agricultural lime, and liming 

 materials shall always mean net weights. 



The order of terms in mixed fertilizers shall be nitrogen first, phosphoric acid 

 second, and potash third. 



When the name of a fertilizer material is used as a part of the brand name of a 

 mixed fertilizer, as, for example, blood, bone, or fish, the nitrogen or phosphoric 

 acid shall be derived from or supplied entirely by the material named. When the 

 name of a fertilizer material is used as a brand or as part of a brand and the nitro- 

 gen or phosphoric acid is not supplied by the material named, the word "brand" 

 shall follow the name of the materials. Example: "Fish Brand Fertilizer." 



The statement of guaranties of mixed fertilizers shall be given in whole 

 numbers. 



As the terms phosphoric acid and potash are used universally in guaranteeing 

 and in reporting the analyses of fertilizers, it is recommended that the same terms 

 also be used in reporting and discussing the results of analyses of related materials.
