Food for The use f sulphate of potash in combination with 



ants Nitrate of Soda, on granite soil, did not pay in 1903. 



I2 4 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 per 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, respec- 

 tively, on two plots on granite soil. In all cases the 

 yield was reduced when the fertilizer was put on in two 

 applications; thus, with 160 pounds per acre applied in 

 two doses, only $4.82 and $7.27 per acre were yielded 

 by two plots on granite soil. 



WHAT PERCENTAGE OF WATER DOES 

 HAY LOSE DURING STORAGE? 



Result of Rhode Island Official Experiment. 



Hay which had been stored during the summer of 

 1901, was removed from the mow the following Febru- 

 ary, and found to contain 12.21 per cent, of water. A 

 careful comparison of other moisture determinations 

 of hay leads to the conclusion that 12.21 is a fair general 

 average of the percentage of water in the best quality 

 of barn-cured hay. When hay is first stored it usually 

 contains from 20 to 28 per cent, of moisture. The loss 

 in storage may be said to be about twelve to sixteen per 

 cent.
