DRY NEUTRAL 



SULPHATE OF AMMONIA 



This material possesses special characteristics- 

 It is dry, resembling silver sand ; it neither cakes 



together nor does it require grinding. 

 It will not absorb atmospheric moisture. 

 It may therefore be strewn on the soil as grass seed, 



or may be readily drilled into the soil. 

 It is neutral and does not destroy the bags in which 



it is transported or stored. 

 It is guaranteed to contain 25^% of Ammonia; 



usually it tests from 25*6 to 25 7%. 

 A typical analysis of the material is : — 



Ammonia ... 25'65% 

 Moisture .... 0*03% 

 Free Acid - - - Nil. 

 Equivalent Nitrogen - 2110%
