56 VEGETABLE GROWING. 



FERTILIZER FORMULA. 



Nitrogen 4 per cent. 



Potash 5 " 



Available phosphoric acid 7 



Use 1,500 pounds of the above formula per acre. 

 When possible, apply twenty to forty tons of vegetable 

 material, such as partially rotted rakings or barn-yard 

 manure. Where such vegetable matter is procurable, 

 the quantity of nitrogen may be decreased proportion- 

 ately. If manure is procurable, allowance should be 

 made for the fertilizer elements contained therein. 



An application of salt is usually considered neces- 

 sary. If kainit is used as a source of potash, we should 

 remember that it contains 30 to 35 per cent, of salt. 



The following table will give the amounts of differ- 

 ent fertilizer material necessary to give the desired 

 quantity of each element :
