TERMS USED IN STATING RESULTS OF ANALYSIS. 
In the tables following, the terms used to express results of 
analysis are self-explanatory for the most part. Attention is 
called, however, to “ water-soluble ” phosphoric acid and nitro- 
gen, and to “ potash present in the form of sulphate.” 
While manufacturers are required to guarantee only the 
amount of available phosphoric acid (water-soluble plus reverted 
or citrate-soluble), yet it seems desirable that consumers should 
know what proportion of the available is water-soluble. The 
amounts of available phosphoric acid being equal, one would 
commonly choose by preference a fertilizer containing the larger 
amount of water-soluble phosphoric acid. 
The water-soluble nitrogen includes nitrogen present in the 
form of ammonia salts and nitrates together with that present 
in small amounts of soluble organic matter. 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 remembered that nitrogen in this form 
leaches and is lost to plants more readily than nitrogen in other 
forms.
