The great value of organic nitrogen has not

 authorities the appreciation due to it,

 from the United Kingdom, for which 

 they are always willing to pay a higher price 

 per unit than for either nitrate of soda or sul- 

 phate of ammonia. No doubt this want of 

 appreciation is in part due to the demonstra- 

 tions now being conducted all over this country, 

 in which the nitrogen is invariably obtained in 

 one or other of the soluble forms, usually sul- 

 phate of ammonia or nitrate of soda, mainly 

 because of its uniform quality ; whilst the equally 

 valuable organic nitrogen is entirely neglected, 

 though many practical farmers have long recog- 

 nised its value, from their own experience. 



It will thus be seen that, in our variable cli- 

 mate, it is never advisable to rely on one source 

 alone for the nitrogen which crops 

 various require, but that it is much safer and

 of availability so that all through the 

 periods of growth the plant receives a continuous 

 supply of this element.
