^ In the light of these figures it would be 
I ell, in making up next spring’s fertilizer 
Irder, which should be compiled early, 
I) consider carefully the agricultural 
|alues as well as the commercial prices, 
nee, as already explained, ammonia in 
1 e organic materials costs distinctly more 
an that in the mineral materials, and 
cording to long-time tests is no more 
ective pound for pound. It would be 
:onomy to use as much of the latter as 
ay be possible without sacrificing in the 
latter of a good mechanical mixture. 
)r example, if the fertilizer contains 
per cent, ammonia (100 pounds to the 
I n), 30 to 35 pounds of this might 
me from an organic source and the 
mainder from a mineral source. If for 
e on potatoes where scab has been bad, 
nmonium sulfate might be used in 
mewhat larger amounts than nitrate 
soda. In buying raw materials make 
re that the acid phosphate is in good 
echanical condition so that when the 
ixture is made it will be easily drillable. 
The organic nitrogenous materials have 
Jeir place, and are not to be discrirtfi- 
ted against when placed on an equal 
noting with other materials, but so long 
the cost is greater than the cost of 
'^her materials that are equally as good 
better, pound for pound of plant food, 
ey should only be used insofar as they 
e required to give a good mechanical 
ixture.

' JNFORTUNATELY there is not al- 
J ways a direct relationship between 
he cost of a fertilizer and its ability to 
ncrease crop yields. For example, years 
if careful study have shown that ammonia 
Q the form of nitrate of soda gives larger 
eturns than an equal amount of ammonia 
n the form of organic materials. At the 
ame timefor the last twenty or thirty years 
minonia in the form of organic materials 
ia s, with only few exceptions, cost the 
armer more than ammonia in the mineral 
aaterials such as nitrate of soda and sul- 
ate of ammonia. 
However, when as much as half the 
,mmonia is taken from nitrate of soda 
ad the other half from ammonium sul- 
ate or some of the organic materials, 
ields of potatoes, as shown by a seven- 
ear test at the New Jersey Station, have 
eeii equal to, or better than, the yields 
nth nitrate of soda as the sole source of 
inmonia. 
The loss of ammonia through leaching 
i great, but contrary to the general belief 
jng-time experiments indicate that the 
jss is less with nitrate of soda than with 
quivalent amounts of the organic mate- 
ials. 
It is quite possible that this may be ex- 
[lained on the basis of the plant’s ability 
a use the readily available nitrate early 
i its growth and thus get an early and 
igorous start, so that it may better use 
be soil moisture, and plant food which is 
ontinually being made available in the 
oil. 
According to quotations taken from 
'he Oil Paint and Drug Reporter (a trade 
)urnal) of December 10, 1923, the cost 
f ammonia in four nitrogenous raw 
laterials was approximately as follows: 
In the form of nitrate of soda, 13.7 
ents per pound; in the form of ammo- 
ium sulfate, 11.2 cents; in the form of 
sh scrap, 24.0 cents; in the form of 
Ankage, 17.8 cents.

P ERHAPS you didn’t know that ferti¬ 
lizer should be “cured” or “aged” in 
order that the food for soil can be more 
readily available when that food is needed. 
This is one of the details of the ferti¬ 
lizer industry that few people know, but 
it’s mighty important. Such “details” 
as this represent the difference between 
Royster’s Fertilizer and less carefully pre¬ 
pared foods—and the difference between 
profitable crops and crops that are not so 
profitable. 
To keep vast quantities of fertilizer for 
months represents an enormous supply and 
a tremendous capital. Therefore, only a 
large company like Royster’s can offer this 
more effective “cured” fertilizer.

Rid yourself of the idea that all ferti¬ 
lizer is alike. This is no more true than that 
all land is alike. 
The truth of this can be proven—not 
alone by the enthusiastic praise of success¬ 
ful farmers who have used Royster’s, but 
by your own experience. 
Use Royster’s this year. Give it a fair 
test—and don’t guess about fertilizer any 
more. 
Grow better and larger crops by using 
fertilizer that has been “cured”—that is 
free from lumps—that has been proven 
chemically correct by forty chemists—and 
that has established a record for good 
works over a long period of years. Look 
for the name “ROYSTER” on the bags.
