POULTRY MANURE Is THE NOS VALUABLE.
The real value is determined by. the eff.
feet of manure on crop yields and on
quality of crop products.
The urine is by far the most valuable
part Of the excreta of animals. It is
especially rich in readily available nj
trogen, which rapidly escapes into the
air If special precautions are not taken
to prevent its loss. It is also rich in
potash, but deficient in phosphoric acid.
It should, as q rule, be used in connec.
ton with the solid dung, the one thus
supplying the deficiencies Of the other
and making a more evenly balanced
manure.
Barnyard MANURE is a very variable
substance. its composition and value
depending mainly upon ~ age and
kind Of animal. C) quantity and quail
ity Of food, C) proportion of litter and
~ method Of management. Ordinary
barnyard manure, properly cared for,
may be assumed to contain on the av-
erage one-half Of / per cent Of nitro
gen;and one-third Of / per cent Of phos-
phoric acid.
Mature animals, neither gaining nor
losing weight, excrete practically as
much fertilizing material as they con
sumo In their food. Growing animals
may excrete as little as 30 per cent as
much as is contained in their food.
mich cows from 65 to IS per cent, fat
tening or working animals from IS to
80 per cent. In the fertilizing value of
equal weights of manure in its normal
condition farm animals probably stand
in the following order: Poultry. sheep.
pigs, horses, cows.
The amounts of fertilizing constitu-
ents In the manure stand in direct rela-
ton to those in the food. As regards
the value of manure produced, the con-
centrated feeding stuffs, such as meat
scrap, cottonseed meal, inseed meal
and wheat bran. stand first. the legu-
mfnous plants Glover, peas. etc.) Sec
ond, the grasses third, cereals (oats.
corn, etc.) fourth, and root crops, such
as turnips. beets and mangel wurzels.

The nitrogen Of the food exerts a,
greater influence on the quality OF the
manure than any other constituent. It.
is the most costly fertilizing constit-
uent. It undergoes more modification

thus Snecessitating the use Of larger
amounts OF litter and affecting both the
amount and value OF the manure.
xBarnyard manure rapidly undergoes
change. When practicable to emove
the manure rapidly and spread 1t on
the field at short intervals the losses
of valuable constituents need. not be
very great. but when the manure must
be stored for some time the difficulties
OF preservation are greatly increased
One OF the best ways to utilize barn
yard manure Is to apply It in connec-
tion with such fertilizing materials as
supplement- Its fertilizing constituents.
These materials may be either COM
posted with the manure or used sepa
rately. except In case Of nitrate, such
as nitrate Of soda.twhich should never
be eomposted with barnyard manure
on account lof danger Of Identification
and loss Of nitrogen. As Is well known,
barnyard manure Is lasting in its
effects ana III many cases need not be
applied 50 frequently as the more
