The Nitrogen of “Sulphate” 
To the Editor of the Garden Magazine: 
Under the heading “Fertilizers” in The 
Garden Magazine for March, I note an 
interesting article entitled “Why Garden 
Soils Need Nitrates,” by Mr. James B. 
Mormon. 
The article is in the main excellent and in 
normal circumstances its advice might well be 
followed. It is only to the last paragraph 
that exception may well be taken. In this he 
says that sulphate of ammonia is not so 
generally recommended and it should be used 
by gardeners with caution until more is 
known about its effect. 
This, I think, is hardly a fair statement of 
the case. Sulphate of ammonia is almost 
universally used by those who use commercial 
fertilizer at all, only they use it as a com- 
ponent of their mixture rather than as a 
separate application by itself. This arises 
from the fact that it is naturally better 
adapted for use in mixtures to form a complete 
fertilizer than is nitrate of soda, although it is 
well recognized by agricultural authorities 
that its beneficial action is the same. It is, 
therefore, probable that Mr. Mormon has 
used sulphate of ammonia extensively when- 
ever he employed a complete fertilizer and has 
enjoyed its benefits without knowing exactly 
to what ingredient they were due. 
In its fertilizing action sulphate of am- 
monia differs very little from nitrate of soda 
except that its nitrogen, being in the form of 
ammonia, requires from a week to ten days 
to become nitrified by the organisms of the 
soil to the form in which it can be assimilated 
by plant life. It is thus a little slower in its 
action than nitrate of soda, but makes up for 
this by continuing its action for a longer space 
of time, making unnecessary the separate ap- 
plications which Mr. Mormon advises. It 
has also the property of being retained by the 
humus in the soil and does not leach out as 
readily in heavy rains. Aside from this, it 
can be applied at the rate of from ioo to 300 
pounds per acre on any garden soil that is in a 
good state of cultivation with entire confidence 
as to the beneficial results. It is admirably 
adapted for top dressing or side dressing after 
the plants are started, or it may be scattered 
broadcast in the seed bed before seeding or 
setting out the plants. It is a well-accepted, 
thoroughly reliable form of nitrogen and 
as such does not deserve to be passed by 
with the casual hesitating comment that was 
accorded it. 
Director Charles E. Thorne, of the Ohio 
Experiment Station, says that “sodium ni- 
trate^and ammonium sulphate have been nearly 
equally effective as carriers of nitrogen and 
both have been equally better than tankage.” 
He made this statement after two years’ 
experimental work on a tobacco-wheat-clover 
rotation. Seventeen years’ test in a corn- 
oats-wheat-hay rotation shows practically 
the same conclusion. So high an authority 
as Dr. A. D. Hall, past director of the 
Rothamsted Station, saj^s (“Fertilizers and 
Manures”): 
“As a nitrogenous manure sulphate of
