POULTRY MANURE IS THE MOS VALUABLE.
The real value is determined by the eff
feet of on crop yields and on
quality of crop products.
The urine is by far the most valuable
part of the eXcreta of animals. 1t is
especially rich in readily available nj
trogen, which rapidly escapes into the
air if special precautions are not taken
TO prevent it's loss. 1t is also rich in
potash, but deficient in phosphoric acid.
1t should. as Il rule. be used in connec
ton with the solid dung. the one thus
supplying the deficiencies of the other
and making Il more evenly balanced
manure.
Barnyard manure is Il very variable
substance. its composition and value
depending mainly upon II, age and
kind of animal. (2' quantity and quail
ity of food. O. proportion of litter and
ID method of management. Ordinary
barnyard manure. properly cared for,
may be assumed to contain on the av-
erage One-half of l per cent of nitro
gen and one-third of I per cen of phos-
phOric acid.
Mature animals. neither gaining no!
losing weight. excrete practically as
much fertilizing material rs they con
sumo in their food. Growing animals
may excrete as little as 80 per cent as
much rs is contained in their food.
milch cows from Ga to So per cent. fat
tening OF working animals from 81 to
30 per cent. In the fertiliZing value of
equal weights of manure in it's 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 INT produced. the con-
centvated feeding stutfs. such as meat
scrap. %cottonseed meal. linseed meal
and wheat bran. stand first. the legu-
minous plants Glover. peas. etc.l sec
ond. the grasses third. cereals Goats.
corn. etc. fourth. and DOT crops. such
as turnips. beets and mangel wurZels.
last.
The nitrogen Of the food exerts Il
greater influence IN the quality Of the
than any other constituent. 1t
is the most costly fertilizing constit.
uent. 1t undergoeS more modification
In the animal stomach than the mineral
constituents potash and phoSphor!c
acid and rapidly escapes from the
manure In fermentation. The secretion
OF urine increases with the increase of
heterogeneous substances in the food.
thus necessitating the use Of larger
amounts of litter and affecting both the
amount and value of the manure.
Barnyard rapidly undergoeS
change. When practicable to remove
the manure rapidly and spread it on
the field ut short intervals the losses
OF valuable constituents need not be
very great. but when the manure must
I've stored for some time the difficulties
OF preservation are greatly increased
One Of the best ways to utilize barn
yard anu is to apply it in connec-
ton with such fertiliZing materials as
supplement its fertilizing constituents
These materials may be either com
posted with the azure or used Snpa
rately. except in case Of nitrate. such
rs nitrate of soda. which should never
be c"mpusted with BARNARD manure
on account Of danger of denitrification
and loss of nitrogen. AS is Well known.
barnyard manur is lasting in its
effects and in many cases need not be
applied so frequently as the more
soluble and quick acting SuperphOs-
plates and potash and nitrogen salts
