From Farmers Review; The best
time 10 apply the wheat fertilizer, fall
planting. Is with the seed 10 Is not
that this Is really the best time. but
that the modern fertilizer and seed
drill makes such an even and thor
ough distribution together with the
economy I'm labor and time quite over
balances any advantage from earlier
applications. The actual plant food
requirements OF the crop are accurate
~ shown by the chemical analysis OF
the crop, including straw, chaff. and
stubble as well as the grain; but, the
nitrogen stored In the soil by le-
gumcs must be taken into account.
II the soil contains too much nitro
gen (ammonla) as compared with the
potash and phosphoric acid. the grain
will run 90 straw. and lodge easily.
even with light rains. This alone
may easily reduce the yield ten per
cent or more. An excess OF phos-
phoric acid as compared with am
monia and potash. Will cause the
grain to prematurely rlpen: the straw
yellows at the ground long before the
head is fully formed. and the result
is invariably n short crop. Potash
has no particular disadvantage II APP
piled in excess. That Is. Il does not
injure the crop. nor suffer any con.
siderable loss In the soil. n fact not
true OF either nitrogen or phosphoric
acid.
II wheat Is planted after corn that
proved light without any specially un-
favorable weather conditions. or II
the corn lodged badly, or tailed 20

soil and should be looked after In the
fertilizer 20 be used In the fall. II
the corn showed an over growth OF
stalk. rank and late maturing. but
falling to produce grain in proportion.
nitrogen Is present In the soil In am
pie quantities. and much less than
the actual crop needs may be used In
the fall fertilizer for wheat. H.
however. the color OF the corn was
light and the growth stuntcd though
not specially early matured. and many
stalks without ears. the soil IS short
Of nitrogen. II the crop very early
turns yellow al the ground and shows
signs OF forced ripening. the phos-
phoric acid Is present In excess OF
needs. at least In comparison with
the nitrogen and potash. II the corn

All these things tend TO give point
ers to the proper fertll!zing OF the
wheat = good crop OF wheat needs
per acre no less than 90 pounds OF
ammonia. 30 pounds OF potash and IS
pounds OF available phosphoric acid.

By watching the cora wc can tell at
least something about the needs OF
the wheat crop so far as the natural
soil Is concerned Olc thing Is very
sure, II for example potash is needed
no great excess OF phnsphoric acid

By scanning the results with corn.
the nature OF the wheat fertilizer Is
outlined. II II Is evident that nitro.
gen Is short. use more Ia the fertilizer
for the wheat In like manner watch
for the Indications Tor both potash
and phosphoric acid. Il Is a very
safe plan 20 use tho plant food rather
freely. as there Is little danger OF loss
from the soil. except In the case OF
