Potash (K) improves the size, yield, shape and sugar content. 



The sulphate of potash is generally used in sugar beet 

 mixtures. 



On land which has been cropped for a long time without 

 any application of potash salts, it occasionally happens that 

 a moderate application of potash salts seems to produce no 

 increase in the yield of beets while a much heavier applica- 

 tion is quite effective. The explanation of this seems to be 

 that the beet is not a vigorous forager for potash and that 

 the soil hunger for the potash is such that it fixes a certain 

 amount too firmly for the beet to get it, but when this 

 amount is exceeded the remainder is available to the beet. 

 Hence, the importance of using a liberal amount of potash 

 for the first application, and of maintaining a suitable re- 

 serve in the soil. 



Amounts to Use 



Most of the plant food used in America is in the form of 

 ready mixed fertilizers. For beet culture a suitable formula 

 for typical loam or sandy loam soils is 



Nitrogen 2 per cent 



Available Phosphoric Acid . . 7 per cent 



Potash 10 per cent 



Of this, from 500 to 1,500 pounds per acre may be used.
