from the air and change It into form
that ID available to plants. In order
for these bacteria to accomplish the
most good the soil condition must be
favorable for their best development.
and this condition II brought about
by the addition of some form Of lime.
There are several forms of lime that
may be used for agricultural purposes
and the choice of the form should de-
pend upon the purpose for which It 10
to be used and also upon the price.
Burned Llms.-Burned lime IL known
also AZ stone lime. lump lime. quick
lime and caustic lime. This form Of
lime II produced from the raw lime
rock by burning. This IL the most
active form of lime and may be used
at the rate Of TOO to 1000 pounds per
acre. Much larger quantities are
sometimes used, but the above amount
should be sufficient in most cases.
This form IL usually obtained In large
Jumps and must be slaked before be-
Ing applied to the soil.
Hydrated llme.-When burned lime
n treated with water It forms what 10
known al hydrated lime. This form
II somewhat less caustic than burned
lime and 10 always In a powdery form
and may be readily applied to the soil.

burned lime.- consequently It should
be used at the rate of about 900 to
1900 pounds per acre.
Air eiaked lIme.--when burned
lime II left to the action Of the air II
takes up moisture and carbon dioxide
and gradually breaks down into q fine
powder. This form Of lime should be
applied in about the same quantities
az the hydrated lime.
Ground Limestone ground
limestone 10 used It should be pulver.
ICED 80 that at least 75 per cent will
pass through q sieve Of 80 meshes to
the inch. Tho value Of the ground
limestone depends quite largely upon
its fineness. This form Of lime IL not
caustic and It may be applied to the
son In almost any quantity without
fear Of causing harm. However, the
usual application would be 1900 to
1000 pounds per acre. One hundred
pounds Of ground limestone are equiv
alent to So pounds Of burned lime or
~ pounds of hydrated lime.
