greatly in its favor so many farmers
have used IL with success in the past

Moreover. IN a year when the fertilizer

ural that our planters should desire

OF the cotton seed raised on their own
farms.

These figures are based on the fact that
a ton Of standard cotton seed meal
contains SIS per cent Of nitrogen equiva-
lent 20 1886. pounds OF this element per
ton: a little better than rs per cent
OF phOsphoric acid equivalent 10 5s.2
pounds OF this element per ton; and
practically 2 per cent Of potash eQuiva-
lent TO 40 pounds OF this element per
tor. The foregoing mixture on a per-
centage basis would contain sos per
cent OF nitrogen, s.S per cent of phos-
phoric acid and I per cent Of potash.
This would be a very good formula to
use on corn and cotton on many OF the

j. not as high IN potash as might be
desirable for truck or garden crops. but
u contains as much OF this element
rs IL is practical 20 secure In almost
any form OF fertilizer available at the
present time. This statement is based
On the excessive price which German
zRIts ara now commanding. and their
scarcity. Of course, some potash is be-
ing produced I'm the United States. but
I is in such demand for commercial pur-
bosses that the farmer could hardly af-
ford 10 use IL.

with some woods ashes. he Will improve
i and advantage himself thereby. The
wood ashes. Of course. should not be
mixed with the acid phosphate and
neal. but should be scattered in the drill
rows and mixed well with the soil or
broadcasted. UnIeached wood ashes will
contain probably TO ) per cent of
potash. and leached ashes about half as
much. Leached ashes are OF little value.
but the unleacheC ashes. some OF which
can be secured on every farm. should
