Points about Sulphate of Potash. 



(4) SULPHATE OF POTASH is defin- 

 itely the best Potash combination 

 for Potatoes, it produces a "mealier" 

 potato than the Muriate of Potash, 

 with a higher starch content, and 

 with superior cooking and keeping 

 qualities. 



(1) SULPHATE OF POTASH is usually 

 sold with a guaranteed minimum of 

 48 % pure Potash. 



Therefore 1 cwt. is an average dressing 

 for 1 acre as against 4 cwts. Kainit 

 (12*4 % minimum). 



A saving in carriage and general hand- 

 ling is thus ettected. 



Besides : — 



(2) SULPHATE OF POTASH can be 



used at sowing or planting time, 

 early or late, without any risk of 

 retarding germination or initial 

 growth. 



(3) SULPHATE OF POTASH has never 



any bad secondary eltect on the soil ; 

 on the contrary, it gives rises in tlie 

 soil to Sulphate of Lime which may 

 be actually beneficial to the crop. 



(5) SULPHATE OF POTASH is like- 



wise the best for Tomatoes, fruit 

 trees, and indeed, for all horticultural 

 crops where quality of produce is 

 important and an excess of Chlorides 

 might prove harmful. 



(6) SULPHATE OF POTASH is dry 



and friable, and remains supreme 

 for mixing with other manures, 

 either on the farm or at the factorv.
