the soil! .
Recause it contains heterogeneous mat
.or nbosphate of lime, potash and lime,
which are the prime agents of fertility, the
most important part of all crops
n Does barnyard manure contain but
these four substances!
A # contains at least ten others, which
WA need not speak about, because plants
a,d them in the soil and ia the air.
q Then sterile soils are wanting III nitro
yonous matter, Phosphate of lime, potash
and lime.
A. Just SO.
O. Then you can always make fertile
soil by the use of these four substances?
A. Yes; you can always grow a go cd
crop by use of them.
O. Is it necessary that these four sub
stances should be in the form of barnyard
manure to De efficacious?
A. 1t is not necessary. Mixing them in
the form of a chemical product gives them
the sane properties. Practically, u che mi
ca fertilizer is more effective than burn
ward manure, and that is easy to under-
stand. In barnyard manure the four fer
tilizing substances are mixed with different
matters whicl detract from its good effects,
while the chemical fertilizer is formed only
Of active parts, which the plants absorb
more rapidly and more certainly; SO to re-
mind you that its e1icacy is always certain
give you the name of complete chemical
fertilizer. The complete chemical fer tilizer,
formed exclusively of chemical products, is
to BARNARD manure what the metal is to
the mineral, what quinine is to the bark of
the cinchJna. The mineral contains the
metal mixed with earthly matters; Gin
chona contains quinine mixed with woody
parts which are useless. The chemical fer
tilizer is barnyard manure deprived of all
useless matter
Q. Then to grow good crops it is abso-
lutely necessary that the soil contains nitro
genous matter, phosphate of lime, potash
and lime; that is to say the four substances
of which the complete chemical fertilizer is
formed?
A. Emphatically. yes.
o IF the soil is wanting in one of these
four substances what happens?
A. In spite of the presence of the three
Others vegetation languishes and your crops
are poor.
Q. How do you know it Is caused by one of
the four substances?
A. Nothing IS easier. Choose a piece of
poor soil, ike that used at the experiment
farm at Vincennes, for example the seat of
Prof. VS. experiments. There the ground
was cultivated several years without barn
yard manure, until the crop went down to
almost nothing. 1t was then laid off into
seVenplots Of 30 feetsquare each divided bv
path feet wide around each plot. The
hrst plot received no manure, the crop was
almost nothing. The second plot received
potash, the crop not much better. The
third received phosphate of lime, crop not
much better The same poverty in the
fourth and fifth, which received only lime
and heterogeneous matter separately. The
sixth received a mixture of heterogeneous
matter, phosphate of lime, potash and lime.
Oha0 is TO say, complete fertilizer; result,
vegetation splendid and there is nothing to
De desired as to abundance and quality of
crop But that is not all; the seventh plot
received mixture of phosphate of lime,
potash and lime. that is to say, complete
FERTILIZER with the exclusion of one of the
lour terms, heterogeneous matter. The Weld
was as inferior IS when the different terms
had been used alone.
1he pre-eminence of the complete fertil-
4zer Iuily proves that It's effect is essentially
due to the collective action arising from the
ASSOCIATION of the four substances COM
prlsingi 1t. To make the discussion easier. I
VIII call mineral fertilizer the union of
phosphate OF lime, potash and lime. that is
TO say, the complete fertilizer without nitro.
genous matter.
THE KEY TO COMPLETE FERTILIZER.
" Ii 1t is true that the complete fertil-
lzer IS only efficacious because it contains
'He Tour substances whose combination
gives the conditions which plant life i'm
perlously demand, then the mineral ferti1-
17r' lacking in heterogeneous matter, must be
inferior in value?
A. Practically that is SO for the majority
y, pants. There are, however, certain
pants upon which the mineral fertilizer
produces quite as much effect as the COM
plete fertilizer.
y What plants are thesea
A. Feas, beans, clover. lucerne, sugar
o@ne' etc., are among the most prominent
of these.
y. these plants then. contain No Nitro.
