DESCRIPTION OF FERTILIZER MATERIALS 

 Materials for Supplying Potash 



Muriate of Potash contains 50 per cent, of actual 

 potash and is one of the most concentrated of plant food 

 materials. As a rule, a pound of potash costs less in the 

 form of muriate than in any other form of potash and for 

 this reason it is the most popular source of potash in mixed 

 fertilizers or for home mixing. Muriate of potash is not 

 generally used, however, on white potatoes, tobacco or 

 citrus fruits. 



Sulfate of Potash is recommended for citrus fruits, 

 white potatoes and tobacco. It may be used upon all 

 crops for which muriate of potash is recommended, and it 

 is sometimes preferred for deciduous as well as citrus fruits. 

 It occurs as a fine dry powder, and is readily adapted for 

 mixing with other fertilizer materials. Sulfate of Potash 

 usually contains 50 per cent, actual potash and is sold 

 under a minimum guarantee of 48 per cent, actual potash. 



Kainit is a crude salt; that is, it has not been refined 

 or manufactured other than being ground into a condition 

 ready for application as a fertilizer. It is sold under a
