(b) Quality of plant-food. 



Attention is again called to the quality of the nitrogen furnished in 

 •the various brands of fertilizer sold in the State. As was pointed out 

 in the 1914 fertilizer bulletin the materials used to furnish the nitro- 

 gen are many and of greatly varying availability. A close study of the 

 results contained in the tables under the heading "Nitrogen" is recom- 

 mended to every user of commercial fertilizers. In interpreting these 

 results, the following points should be remembered: That water-so- 

 luble nitrogen is readily available for plant uses. That the water-inso- 

 luble nitrogen ("active insoluble" and "inactive insoluble") may or may 

 not be readily available for plant uses. 



When tJie amount of '^active insoluble' nitrogen is greatei- tJian the 

 amount of ^'inactive insoluble" nitrogen, the total water -in soViible nitro- 

 gen is considered to te readily available to plants; when the amount of
