soluble nitrogen varied from to 5.03 per cent and averaged 

 0.94 per cent. This constituted 43.2 per cent of the total nitrogen 

 present. It should not be inferred that water-soluble nitrogen 

 is of more value than the rest. It is, of course, more readily- 

 available, so far as it consists of nitrates, but it must be remem- 

 bered that nitrogen in this form leaches and is lost to plants more 

 readily than nit*ogen in other forms.
