amount of these elements required as
plant food is respectively as follows:

Ohiclum '.''.... l6S lbs.
PHOSPHORUS .............. II lbs.
Now. ii has been determined that
Calcium enters largely into the straw
stalks and hay and that magnesium
enters to considerable extent, yet
when you compare Calcium with Mag.
nesium content of grain. you will find
three times as much Magnesium in
grain as Calcium.
DIR. Hopkins states that the average

soils in humid sections is known by
the results of many analyses, to be
about as follows:
POTASSIUM .............. 10 lbs.
Calclum ................ 800 lbs.
Phosphorus ......... 2 lbs.
Now, as for Magnesium, it seems
probable that thirty lbs. or more will
be sufficient annual less to be esti.
mated for Magnesium. II is found that
the loss of Calcium by teaching is much
greater than that used as actual plant
foods. while the loss of Potassium is
relatively small. Potassium is very
abundant in normal soils, while Phos.
phorus is relatively deficient. II
seems to be fact that Calcium and
possibly Magnesium play important
parts in bringing about n full supply
of plant food, and permanently I'm.
proving lands. When growing clover
and alfalfa, it is necessary to provide
supply of Calcium, because four tons
of clover takes up 100 lbs. of Calcium,
while four-ton crop of alfalfa re-
quires 145 lbs. of Calcium. Now, then.
to determine how much lime it will
take to supply this amount of Cal.

stone per acre to supply Calcium plant
food per acre per annum for alfalfa
but limestone usually contains Mag,
nesium and silica. So that 500 lbs
per acre is none too much. Then on
the same basis IL will take $50 lbs. of
pure limestone to stand the teaching,
and 1000 lbs. per acre of lime, con.
tanning Magnesium, and the impurity
silica. So it follows that an alfalfa
crop requires at least 1900 lbs. of lime
per annum. If several years are to
be provided for, two tons should be
provided per application, but If the
sub-soil shows to be acid, it will take
about four tons of lime per acre to
correct this acidity, so that the bac.
terra will be induced and permitted to
thrive and work in catching nitrogen
from the atmosphere.
We have found some ground lime
stone carrying lbs. of Phosphoric
Acid to the ton, and on this account
2 l3 tons OF it applied per acre would
furnish as much of the element Phos.

Ground limestone is very soluble in

Ground limestone carrying a heavy

We wish to be understood that

ground phosphate also carries 62 pei

that one ton of Phosphate CARRIES 30,
