Good Quality Of Bat Guano
Best for Orchards.

In response 10 a query regarding
orchard fertilizers. X. r. Hare, chem
list al the Agricultural College Expert
ment station, has issued letter which
deals with the question at length. The
bulletin dated at Agricultural college.

Dear Sir; Professor Garcia has re-
ferred to me that part OF your letter
10 him under date OF Nov. 2sth, which
asks for the information regarding fer
tillzef Tor your orchard.
You are perhaps aware that the
California fruit growers are using bat
gnano from the Carlsbad caves and
from any other source from which
they are able 10 obtain Il. ! am very
much OF the opinion that n good qual
ny OF this guano IL the best thing you
can use for your trees n you are UNI
allie to obtain sufficient stable man
ure. No experiments have ever been
made to determine what amount of
each fertilizer IL best for New Mexico
soils. Indeed we have no experiment.
nj proof 20 show that our orchards
have ever been benefited by the APP
pllcation OF fertilizers Chemical an
nlyses Of our soils sometimes Indicate
a scarcity OF nitrogen. phosphoric
acid aud humus. These are supplied
best and cheapest from stable manure
and bat guano. The hat guano Ia the
more concentrated fertilizer Of the
two and contains nothing that will
hurt the trees. | would advise adding
all the way from 600 TO 1000 pounds
per are, spreading Il underneath the
tree and plowing under. In Califor-
MIA much less OF the guano II used
on the citrne trees than / have adyo-
Gated for your apples. but while they
must pay from $40 TO $50 per ton for
the gnano. y0u can get Il at from
Sfh to s20 per ton. The amount to be
added really depends upon the COM
position OF the suan0. which varies
great deal In composition. as may
be seen by references TO the report OF
the chemist In the eighteenth annual
report OF the director OF the station.
For this reason. IN purchasing baf
guano the amount OF ammonia and
phosphoric acid should be guaranteed.
In n recent communication from
the California experiment station /
am advised that, ON account Of the
large proportion Of nitrates and ami
inohia salts, bat guano Is considered
q quick acting fertilizer. They further
state TINT In their opinion the old
idea that bat guanos are inferior be-
csnse OF the slowness of decay OF
their organic nitrogen, has heen
greatly exaggerated They say that
II Is doubtless true that quite IA pro-
portion Of the organic nitrogen derived
from insect or animal tissue IA rather
slowly available. but believe that nat
snano as whole is of high available.
ny. Hat guano is sold in California
IN the pure form, mixed elth gypsum.
aud also snixad with other plant foods.
A rather significant fact that speaks
wen Tor bat guano as n fertilizer Ia
mas the manufacturers uenerally
guarantee their mixed fertilizers as
'oniainlng bat snauo, which means OF
curse that ,hls Il popular fertilizer
With the California farmer.
II yonr trees are not bothered with
aikali mat you are able to wash on
DR. drain out OF the SOIL cultivation
and fertilization will doubtless greatly
benefit them.
Very truly yours.
