desired to apply sulphate of ammonia with one of these 

 substances to any particular area, the phosphate should 

 be put on a month or more before the other substance. 

 Sulphate of ammonia may, however, be mixed with the 

 other ordinary manures, such as superphosphate, dis- 

 solved bones, bone meal, kainit, sulphate and muriate 

 of potash, and nitrate of soda. Nitrate of soda should 

 not be mixed with superphosphate, dissolved bones, or 

 dissolved guano. Not only may such a mixture result 

 in the loss of nitrogen, but the mass is apt to become 

 sticky and difficult to sow. Superphosphate and dis- 

 solved bones should not be mixed with basic slag or 

 precipitated phosphate, as this results in the soluble 

 phosphate of the superphosphate or dissolved bones 

 becoming insoluble. 



Potash manures (kainit and sulphate or 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 because 

 the mass is apt to become smeary and unsowable.

 ject of manures and manuring and published by the 

 Board which the grower should study is : " The Purchase
