An inspection of the summary of results shows that 

 the heaviest yields of hay on both red and granite soils 

 and the largest money returns per acre were obtained 

 from the plots which were fertilized with phosphate 

 during 1901-2. On red soil with oats-hay the gain from the 

 use of Nitrate of Soda on the plot which had phosphate 

 the year previous was $11.70 per acre, as against only 

 $3.72 per acre where the Nitrate was used on land having 

 no previous fertilization. 



On granite soil with oats-hay there was no gain from 

 the phosphate. The use of Nitrate of Soda alone without pre- 

 vious fertilization yielded $9.44 per acre profit, while on the 

 plots having phosphate applied the previous year, the gam 

 was only $5.74 per acre. 



In 1903 the heaviest yield of hay was obtained from 

 oats, and the largest profit per acre from wheat on granite 

 soil which had an application of Thomas slag, sulphate of 

 potash, and lime, in 1902. Nitrate of Soda was used at the 

 rate of 320 pounds per acre in 1903. The yield of hay was 

 5,772 pounds per acre, and the resulting profit $12.89 P er 

 acre. It should be remarked here, however, that this plot was 

 fertilized at a loss of $21.50 per acre in 1902; and as the ap- 

 plication of Nitrate was larger than was used on any other 

 plot, the increased returns were at least partly due to the in- 

 creased supply of the Nitrate. 



The use of sulphate of potash in combination with Ni- 

 trate of Soda, on granite soil, did not pay in 1903. Potash 

 was used at the rate of 300 pounds per acre. In most cases 

 the fertilizer cost more than the increased crop of hay; hence 

 its use incurred a loss of from 76 cents to $4.57 P er acre. 



The experiments with Nitrate of Soda used alone were 

 broadened in 1903 to test the efficacy of different amounts 

 per acre and the division of the application into two doses. 

 The results show that in 1903, 160 pounds of Nitrate of 

 Soda per acre in one application yielded the largest profits, 

 viz.: $9.44 and $8.90 per acre, respectively, on two plots 

 on granite soil. In all cases the yield was reduced when 

 the fertilizer was put on in two applications; thus, with 

 1 60 pounds per acre applied in two doses, only $4.82 and 

 $7.27 per acre were yielded by two plots on granite soil.
