12 FERTILISERS AS AN AID TO 



Phosphates 



Phosphates are indispensable for successful 

 farming. They are a necessity for the healthy 

 development of all plants and animals. Phos- 

 phates are constantly being removed from the 

 land in the grain and seeds, the bones, muscle 

 and milk, therefore they must be replaced 

 liberally if the crops and animals are not to 

 suffer. 



The effect of phosphate, the active principle of 

 which is phosphoric acid, is the very 

 opposite to that of nitrogen, an 

 excess of which delays the maturing 

 of crops. On the other hand, phosphate not
