College Education for Farmers

The managers of the State Agricultural
Experiment farm at New Brunswick have
arranged to hold the fourth annual sum-
mer field day meet at the farm on Tues
day, August 9th.
These field day meets have proven
wonderfully interesting and instructive
to farmers, and preparations are being
made to take care of a larger gathering OF
farmers this year than at any Of the pre-
yious meetings, The highest development
OF farming is demonstrated and farmers
who attend will find much TO instruct as
well as to entertain. The men at this
experiment station are doing excellent
service in working out agricultural prob
lens, and il the farmers OF the State will
take advantage of the knowledge which
these men will give them for the asking
they will be greatly benefited. All
farmers who can will be greatly protited
by attending the field day meeting, as the
practical results of theoretical expert
ments will be open for every one to see.
Edward b. Voorhees,, A. NJ, director
OF the New Jersey Agricultural Expert
ment Station aud Professor of Agriculture
in Rutgers College, New Brunswick, has
written one OF the most practical books
on the First Principles OF Agriculture,
which should be in every farmers hands.
While it is not as practical nor attractive
with illustrations as other books, yet the
scientific part Of agriculture is treated
upon in such a simple manner that all
who read may understand.
On the use of kaipit, which is-some-
what used in this region, Professor Voor-
bees says;
"This is the only crude product that is
largely used directly upon the land, 1t
is composed OF a number OF salts, chiefly
Sodium Chloride or ordinary salt, mag
neslum chloride, magnesium sulphate,'
and potassium sulphate.'
although the potash in kainit is in the
form OF a sulphate, it's effect is quite SINH
lar to that derived from the use OF
muriate, because of the large quantities
of chlorides contained in it, in combine
ton with magnesia and soda. 1t is not
rich in potash, containing on the average
twelve and one-half per cent OF actual
potash or potassium oxide.
"These crude salts are valuable as in.
direct manure in that the salts present,
other than the potash, have a solvent
effect upon other soil constituents, par
ticularIy phospbates; they also aid in
many cases in improving the physical
character Of soils. 1t is believed, too,
that the magnesia contained i'll them
serves us direct food under certain cir
cumstances, though this point is not re-
garded of great importance.
DIN the use of these forms OF potash, it
is recommended that their application
should precede bv a considerable time
the planting of the crop in order to avoid
danger to the young plant from an excess
of magnesia salts, which injure the tender
rootlets and plants. and also that the ex
cess OF chIorides, which sometimes infu-
ence ~unfayorably the quality of produce,
may be washed from the surface soil by
she rains.
On Germany, where The use OF these
potash compounds has received most
careful study, their application is almost
invariably made in the fall of the year,
or upon the crop preceding the one which
is in especial need OF potash fertilization.
In this country, owing to our happy
spring rains, an early spring application
will doubtless answer quite as well in
most cases."
