ern States included in our discussion, we find a gain of 7.9 Food f r 

 bushels of wheat and 1,340 pounds of straw, and a valuation Plants 

 of seventy-five cents per bushel of wheat and $6 per ton for 6 5 

 straw, which prices probably represent the average, though 

 not as high as are now prevailing, the total value of the 

 increase is $9.95, or a net gain of $6.20 per acre, using the 

 high price of $50 per ton for the Nitrate of Soda. The profit 

 here indicated is a good one and should make wheat raising 

 more encouraging, besides stimulating the farmer to better 

 practice in other directions. The calculated yields from the 

 use of Nitrate are not unreasonable to expect, since on good 

 wheat soils and with fairly good management, without the 

 additional Nitrate, the average yield is over twenty bushels 

 per acre. 



In reference to the second question, as to _. . 

 how much Nitrate shall be applied, the . . 



experiments show that on soils in a good 

 state of cultivation, those that will produce from, say, fifteen 

 bushels per acre, without top-dressing, 150 pounds per acre, 

 the average amount used in the experiments, would be the 

 most useful; though, on poorer soils, which would average 

 ten to twelve bushels per acre, 100 pounds would be better, 

 for the reasons already discussed in the case of hay. 



On better soils, where quantities larger than 150 pounds 

 per acre seem desirable, it is strongly recommended that two 

 applications of equal weight be made; the first, when the 

 plants have well started, and the second, when the crop is 

 coming in head. Very often the season is such as to encour- 

 age a rapid change of the insoluble Nitrogen in the soil, in 

 which case too large an application in the spring would tend 

 toward an undue development of leaf and the ripening would 

 be impaired, hence the advantage of dividing the amount is 

 apparent, as, if the season is good and the growth normal, 

 the second application may be dispensed with. Where the 

 soil is liable to be deficient in minerals, and this is often the 

 case, the Nitrate may be mixed with other materials, as 

 recommended for hay, the excess of minerals not used for the 

 wheat providing for the following crop. 



The three experiments with rye in R 



1894 confirm the conclusions reached in 

 both the experiment on hay and wheat, that Nitrate of Soda
