gen, 24 pounds of phosphoric acid, and 30 pounds of 

 potash; this includes the straw, chaff and stubble. 

 One hundred pounds of Nitrate of Soda supplies 

 about 15 pounds of Nitrogen, so that the quantity 

 mentioned for application is a minimum quantity. 

 Much has been said of legume Nitrogen for wheat, 

 the crop being generally grown in rotation. What- 

 ever 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 all cases where the 

 acre yields have fallen off, a broadcast dressing of 

 Nitrate of Soda should be given. 



Drill in with the wheat in the fall a mixture of 150 

 pounds of acid phosphate and 50 pounds of Nitrate of 

 Soda per acre. If your land is sandy, add 50 pounds 

 of sulphate or muriate of potash to the above. Early 

 in the spring, sow broadcast 50 more pounds of 

 Nitrate of Soda per acre. 



Land sown to wheat in the fall and seeded down 

 with timothy and clover giving a heavy crop, fol- 

 lowed by a heavy hay crop the following year, proved 

 the beneficial after-effect of the Nitrate and that the 

 Nitrate had not leached away as so many critics 

 claim, and further that the soil had not been ex- 

 hausted. 



Professor Massey writes in regard to the effect of 

 Nitrate of Soda on Wheat, as follows : 



"I have made several experiments w^ith Nitrate of Soda. 

 The first was on wheat in Albemarle County, Virginia. I 

 used 200 pounds per acre on part o£ the field which had been 

 fertilized with 400 pounds acid phosphate in the fall. The 

 result was 9 bushels per acre more than on the rest of the
