Food for Most manufacturers and dealers in fertilizers are 



- ans willing to supply farmers with the materials suggested, 

 2 46 or to mix them at reasonable rates. 



If you cannot conveniently get all the materials for 

 mixing your formulas and can secure any reputable 

 brand of ordinary commercial fertilizer, buy a bag of 

 Nitrate of Soda and mix it with four to six bags of 

 such commercial fertilizer; and the mixing may be done 

 on your barn floor. You will thereby improve and 

 fortify the brand you are buying in a way to vastly en- 

 hance its crop-making powers. 



If the Nitrate should happen to be lumpy, the use 

 of a straight, heavy fence post, rolled over it two or 

 three times will reduce it to splendid condition for home- 

 mixing. 



One hundred pounds of Nitrate of Soda is equal in 

 bulk to about one bushel, or 25 pounds to about one 

 peck. 



Materials Not To Be Mixed. 



Certain ammoniates contain iron, and if mixed 

 with acid phosphate you will lose a considerable portion 

 of your available phosphoric acid. 



Lime should not be mixed with sulphate of am- 

 monia and materials containing lime, should not be 

 used in this connection without advice from an ex- 

 perienced fertilizer chemist. 



Excessive quantities of lime should not be mixed 

 with superphosphate, barnyard manure or bone meal. 



Sulphate of ammonia should not be mixed with 

 Thomas slag and Norwegian Nitrate. 



Basic slag should not be mixed with sulphate 

 of ammonia, blood or tankage as the lime affects 

 these materials and releases ammonia. If mixed with 

 kainit it must be applied shortly after mixing. 



Cyanamid must not be mixed directly with sul- 

 phate of ammonia, but if mixed according to directions 

 will give good results.
