commonly fertilized crops, 

 particularly the latter. The 

 average fertilizer for wheat 

 should contain Nitrogen, 

 phosphoric acid and potash. 

 This fertilizer is applied with 

 the seed, and at the rate of 

 500 pounds to the acre. Ni- 

 trate of Soda is also applied as 

 a top-dressing, soon after the 

 crop shows growth in the 

 spring, broadcast, at the rate of 

 100 pounds per acre. Like all 

 grains, wheat should have its 

 Nitrate plant food early, and 

 in the highly available, easily 

 digested Nitrated form, such as is only to be found commer- 

 cially as Nitrate of Soda. 



The plant food needs of a crop of 30 bushels 

 of wheat per acre amounts to about 70 pounds 

 of Nitrogen, 24 pounds of phosphoric acid, and 30 

 pounds of potash; this includes the straw, chaff 

 and stubble. One hundred pounds of Nitrate of 

 Soda supply about 16 pounds of Nitrogen, 50 that the quan- 

 tity mentioned for top-dressing is a minimum quantity. Much 

 has been said of legume Nitrogen for wheat, the crop being 

 generally grown in rotation. Whatever Nitrogen the clover 

 may have gathered, a crop of timothy and a crop of corn must 

 be supplied before the wheat rotation is reached. In many 

 cases, simply top-dressing with the Nitrate will be found ef- 

 fectual. In all cases where the acre yields have fallen off, top- 

 dressing of Nitrate of Soda should be applied. 



Professor Maercker states that Nitrate of Soda for 

 wheat is absolutely necessary under the conditions in Ger- 

 many, and that 100 pounds of Nitrate of Soda produces 300 

 to 400 pounds of grain and a corresponding amount of straw. 



.Drill in with the wheat in the fall a mix- 

 ture of 250 pounds of acid phosphate and 

 50 pounds Nitrate of Soda per acre. If 

 your land is sandy, add 50 pounds of sul- 

 phate of potash to the above. Early in the spring, sow 

 broadcast 100 pounds Nitrate of Soda per acre.
