amount of phosphorus to 121per cent and
the potash to 8 or Z per cent. On an

crop is half grown is a good practice.
or that it viii result In Increasing the
yield of grain materially.
There is great difference in varie-
ties of corn. some tending to produce
much more stalk in proportion to grain
than others. We believe, as a rule.
the prolific varieties will be found more
satisfactory as to yield than the non-
prolific varieties on most upland soils
II you are not cultivati,.g the prolific
corn. try it this year. 1t is also i'm
portant to bear IN mind that corn re-
quires large amount of vegetable mat
ter and nitrogen in order to give its
best Yield. 1t is possible that while your
corn is producing a relatively large stalk.
the soil may not be well enough supplied
with those elements to enable the stalk
to grow and mature one or two good
ears. A surplus of available plant food
in the sol Will nearly always result in
Increased Yields. and in Its absence the
yield is likely TO be limited For this
reason we suggest the use of a high
grade fertilizer well supplied with the
mineral elements.

would like little Information in regard
TO commercial fertilizers What is pot
ash salts, also nitrate of potash and.
muriate Of potash? rs II usually accept
ed that potash should be applied to
strawberries and fruit trees in the form
OF sulphate? ] have poor luck getting
plants to grow that are set out on land
that has been fertilized with commercial
fertilizer that contains potash salts
What is the reason of this loss? I
BY potash salts you probably refer to
kaint. which is the most common product
Of the Stassfurt mines IN Germany. and
which constitute the chief source from
which potash materials for fertilizing
purposes are obtained. KANT contains
about 70 TO a per cent of potash In the
form Of sulphate At the same time
there is present a considerable quantity
Of common salt some chloride and sui
plate of magnesa, small amount of
gypsum and a small amount of potas-
SUM chloride KANT is low grade
material. four tons of If being required
to furnish the same amount of actual
potash as one ton of high grade muriate
or sulphate. Since it contains. chlorides
il should not be used on such crops as
tobacco. potatoes. onions. etc. as il is
likely to injure the quality. II should
generally be applied so 1t win not come
in contact with the seed as II Is likely
to injure termination.
Nitrate of potassium commonly known
as saltpetre. and largely used In the
manufacture OF gunpowder. is a coneen-
trated material. containing both nitrogen
and potash In available forms. or avail
able nitrogen, there is generally present
about 10 per cent. and of potash about
~ 10 As per cent. This material Is sell
dom used as fertilizer because OF its
high price.
Nitrate of potash is one of the prin-
cipal sources of potash on the market.
Like Kainit il Is obtained from the
Stassfurt mines In Germany. 1t is puri-
fed after being mined. and Is put on
the market in form which gives il the
equivalent of 30 to SO per cent of actual
potash 1t Is most commonly used as
fertilizer and Is a favorite because Of
its concentrated form. aud relative low
cost per pound of available plant food.

it contains a small quantity of this ele-

hand Is free from chlorine. and cam be
used TO advantage on crops TO which
muriate Is not Well adapted. The idea
of applying potash to fruits is due to
the fact that it Is an essential const-
tuent I'm their growth. not only being
present I'm the ash in relatively large
Quantity, but because Il forms the basis
OF the well-known fruit acids. This data
