Annual Report for 1911 of the Consulting Chemist. 'Ml 



B. Fertilisers. 

 1. Sn/ierjjJiosphnte. 



This has been uniformly good. A sample sent to me, 

 and guaranteed to contain 30 per cent, of soluble phosphate, 

 cost 51s. per ton delivered in Hampshire. The analysis 

 showed it to have soluble i)hosphate 31'6G per cent, insoluble 

 phosphates 3-OlJ per cent., and the material was of very good 

 value, the price working out at Is. Id. per unit of soluble 

 phosphate only. 



2. Fish Manure. 



The following are analyses of two samples of fish manure 

 sent me : — 



Water 



'Organic matter . 

 Phosphate of lime 

 Alkalies, &c. 

 Sand 



' Containing nitrogen . 

 equal to ammonia. 



"A" was guaranteed to contain 8 per cent, of ammonia, 

 and cost — in Kent — 61. 15s. per ton, while " B " was guai^anteed 

 to contain 6 per cent, of ammonia, and cost 61. Ds. per ton. 

 It will be noticed that they both of them came below the 

 guarantee, and I consider them both extremely dear, more 

 especially " B." 



3. Fruit Manure. 



This, w-hich cost 7/. 17,v. 6d. per ton in Kent, gave the 

 following analysis 



It came practically up to the guarantee under which it was 

 sold, but must be considered distinctly dear, and 61. a ton 

 would be an ample price. 



4. Sulphate of Ammonia. 



It is not often that this is found to be of inferior quality, 

 but a sample sent to me, guaranteed to contain 25 per cent, of 

 ammonia, showed only :—
