20 FERTILIZERS AND AGRICULTURAL LIME 



DRIED ANIMAL MANURES 



Continuing the inspection of the quality of dried animal manures being sold in 

 Massachusetts, all samples of these products were subjected to both microscopic 

 examination and chemical analysis. The results are given in the next table. 



Four lots were found mislabelled and consequently were withdrawn from sale. 

 Some of the other lots sampled contained large amounts of bedding material but 

 not in sufficient quantity to warrant withdrawal from sale. 



Aside from materials used as bedding, a reasonable amount of which is to be 

 expected in animal manures, the most common contaminant found in large amounts 

 is sand. This, also, is a normal constituent of animal manures. However, the 

 presence of 40-, 50-, or 60-percent sand is an indication of either deliberate adultera- 

 tion or over-enthusiasm in the deep use of shovels or scoops when removing the 

 manure from the stockyards. 



In the future, the Massachusetts Fertilizer Control Service will require 

 that all dried animal manures containing more than 30 -percent sand be 

 labelled as "Sheep Manure and Sand,", "Cow Manure and Sand," etc. 

 The word "sand" shall appear in the same size type as the other words in 

 the brand name.
