lsed as fertilizer in three different
forms; as organic matter, as ammo
MA and ~ q nitrate. Organic nitro
gen exists i'm combination with other
elements either as vegetable 1r AMI
NAL matter; all plants and all ami
mails contain certain amount Of
organic nitrogen. This organic
nitrogen decays or goes through a
state known m nitrification, which

vegetable matter. dried fish. dried
blood, dried meat scraps. tankage
and numerous other vegetable AID
animal compounds. The value of
IN organic ampioniate or organic
nitrogen depends upon its physical
composition, that is, whether or
not il readily decays. In the case
Of blood or cotton seed meal this
decay or notification is comparative
~ rapid and consequently both OF
these substances are excellent for
fertilizing purposes. On the other
hand, leather meal is Of such a
physical combination that it resists
decay and for that reason Is not
considered a good fertilizing mater.

The nitrogen as ammonia occurs
i'm commercial manure products il
the form of sulphate of ammonia,
chloride of ammonia and other am.
moniate salts. II is more readily
available than nitrogen in organi,
form, that is, il goes into the form
Of q nitrate more readily and is cor
respondingly more valuable thar
organic ammonia. Nitrogen as Q
nitrate exists in the form of nitrate
of potash and nitrate of soda; in
these cases the nitrogen is imme'
diately available. Nitrate of potash
is comparatively scarce compound
and il used only to a very small ex'
tent. Il is much more valuabl,
than any other form of nitrate since
it contains both nitrogen and potash

more plentiful than nitrate Of potash

price. Ii is the chief source of nj.

word Tankage" however. is very
elastic and is applied to a great

tankage is combination of blood,

term is used oftentimes to describe
inferior products snch as garbage
