sent the average, though not as high as are now pre- 

 vailing, the total value of the increase is $9.95, or a 

 net gain of $6.20 per acre, using the price of $50 6 7 

 per ton for Nitrate of Soda. The profit here indi- 

 cated 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 aver- 

 age yield is over twenty bushels per acre. 



In reference to the second ques- 

 tion, as to how much Nitrate shall be to A 

 applied, the experiments show that on 

 soils in a good state of cultivation, those that will 

 produce about 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 recom- 

 mended that two applications of equal weight be made; 

 the first, when the plants have well started, and the 

 second, when the crop is coming into head. Very often 

 the season is such as to encourage 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 dis- 

 pensed 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 Rye. 

 1894 confirm the conclusions reached in 

 both the experiment on hay and on wheat, that Nitrate 

 of Soda as a top-dressing proves desirable in effectually
