ASHES. 



The Connecticut Station examined 55 samples of cotton hull ashes, and 

 found that the highest percentage of potash was 36.45, and the lowest, 10.26. 

 The average percentage of potash in all the samples was 22.4 The Ontario 

 College and Experimental Farm Report for 1897 gives the composition of the 

 ashes from different kinds of wood as follows : 



"The fact that these ashes were pure and prepared from the wood only, 

 explains why the percentages of mineral constituents are so much higher 

 than in those found in the average ashes of the market." 



PERCENTAGE OF THE AVAILABILITY OF THE DIFFERENT FORMS OF NITROGEN. 



The Connecticut Station, in a series of experiments with oats and Hun- 

 garian grass, found the availability of the nitrogen in different combinations 

 as follows : Putting nitrate of soda as the standard of comparison 



Per cent, available. 



Nitrate of soda 100.00 



Dried blood 73.30 



Dry ground fish 63.90 



Ground bone '. 16.70 



Tankage 49.40 



Horn and hoof 68.30 



Linseed meal 68.90
