soluble nitrogen varied from 0 to 5.03 per cent and averaged 
0.94 percent. 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 nitrogen in other forms.
