as this results in the soluble phosphate of the super, or dissolved 

 bones becoming insoluble. 



Potash manures (kainit and sulphate and muriate of potash) 

 should not be mixed for more than a few hours with any 

 " dissolved " manure {e.g., superphosphate and dissolved bones), 

 not because anything is lost, but simply because the mass 

 becomes smeary and unsowable. 



Generally speaking, the sooner a mixture of manures is sown 

 after it is made the better. Some mixtures, as has been 

 indicated, get smeary, others get lumpy, while others, like basic 

 slag and kainit, may actually become a hard, solid, stone-like 

 mass, which the ordinary appliances of the farmer are insufficient 

 to deal with.
