FERTILIZER AND AGRICULTURAL LIME 13 



AGRICULTURAL LIME PRODUCTS 



Manufacturers and Brands 



During 1948, 11 firms registered for sale in Massachusetts 23 brands of lime 

 products, manufactured and sold for neutralizing acid soils. The products are 

 grouped as follows: 



Hydrated or slaked lime 15 



Ground limestone 8 



23 



The analytical results which appear in this bulletin represent officially drawn 

 samples secured by the same sampling agents who drew the samples of com- 

 mercial fertilizer which served for the inspection of that commodity; the samples 

 therefore cam.e from every section of the State and are, we believe, representative 

 of the lime products sold in Massachusetts as soil amendments. 



We were not successful in securing samples of the following brands: 



Conklin Limestone Co., Inc., Canaan. Conn.

Explanation of Table of Analyses 



Tables I and II: "Neutralizing value expressed in terms of calcium oxide" 

 represents the acid neutralizing value of both the magnesium and the calcium. 

 The figures in the "percent" column are obtained by a direct titrc-tion with 

 standard acid. The "pounds in one ton" are secured by multiplying the figures 

 in the "percent" column by 20. 



"Insoluble matter" represents material which is insoluble in dilute hydrochloric 

 acid to which a few drops of nitric j.cid have been added, and is mainly sand. 



Under "Mechanical analysis" the figures represent the percentage of product 

 that would pass or be retained by the meshed sieves mentioned.
