INSPECTION OF COMMERCIAL FERTILIZERS 3 



Second, the analysis of some fertilizers, notably those containing high percent- 

 ages of plant food, shows conclusively either that these fertilizers had been im- 

 properly mixed or that segregation had occurred after mixing. In such cases the 

 analysis shows one or two elements considerably above guarantee, while the third 

 element is generally considerably below guarantee. In these instances the manu- 

 facturer has used sufficient quantities of all ingredients to meet his guarantee 

 fully, but due to variations in the mixture, perhaps to some extent unavoidable, 

 the analysis of some lots shows a large deficiency in one element with overruns in 

 other elements. This reasoning cannot apply to those mixtures which by analysis 

 are shown to be seriously deficient in two elements with only a slight overrun in 

 the third element, or to those having deficiencies in all elements guaranteed. This 

 brings us to the third factor. 



During recent years the competition among all fertilizer manufacturers has 

 become much keener, resulting in an increased incentive to gain business by mak- 

 ing price concessions and offering other inducements to the buyer. Since this pro- 

 cedure inevitably leads to a reduced margin of profit, some manufacturers in 

 calculating their mixture formulas may have been tempted or forced to figure 

 their raw material costs a little more closely than is consistent with good fertilizer 

 mixing practice. 



MANUFACTURERS AND BRANDS 



Registrations have been perfected in Massachusetts during 1940 by 98 firms, 

 covering 491 brands of mixed fertilizer and unmixed fertilizing materials. 



The following brands were not found on display by the sampling agent at any 

 point in the state and therefore do not appear in the tables of analyses.
