 Description. 

 "Soluble," i.e. soluble by the methods prescribed by the Regu- 

 lations 25s. Od. 



In addition 255. per ton is allowed for mixing, bagging, 

 etc., and a further charge for credit. 



Thus, the price per ton of a Compound Fertiliser of 



the following composition : 



Nitrogen 4 per cent, (of which 3 in Class 1). 

 Phosphates 20 per cent, (of which 15 soluble in water. 



4 in citric acid, and 1 insoluble). 

 Potash 2 per cent. 



This is the net cash price, and if any addition is made 

 for credit its amount must be distinctly stated. 



The Order does not apply to mixtures made up to the 

 farmer's specification. 



As a rule Compound Fertilisers in England contain 

 about 3 per cent, of nitrogen, and in Scotland a little 

 more. The best makers use only Class I nitrogenous 

 materials.
