OF winter cover crops is that they

Sun another advantage is that they

PERIOD or time, from October l to

In which to grow something of bene-
Mt to the soil and to increase the
farmers income. There are those
who object to pasturing animals in
the cotton fields in the winter, and
these objections are sometimes valid
Farmers must be their own judges as
to what soils can be pastured and
under what conditions this can be
done. But even IL no pasturing is
done, winter cover crop should be
there Just the same, for it is very
advantageous In other ways.
Some experiments have been made
with certain winter legumes as cover
crops, with q view to increasing the
fertility of the soil At the North
Carolina Experiment Station bur Glow
er was sowed between the rows of
Gotten when the crop was laid by
and was plowed down the following
spring as a fertilizer for the cotton
crop the next year. They report that
the value Of the cotton grown where
bur clover was plowed under was SIS
more per acre than where no cover
crop was used. This increase of
value is so great that it ought to in
terest every farmer In the idea of
sowing a cover crop In his cotton
field. Even If the increase had been
only half what 1t actually was il
would have paid a larger per cent on
the investment.
In the fall of 1907 Mr.. L. NJ. Cook.
Grand Cane, La. sowed 20 pounds Of
the seed OF hairy vetch on one and
one-half acres of his cotton field. He
grazed sheep on it during the winter,
but much of it reached a height of
a foot or more in the early spring
before the land was ploWed. Cotton
was planted on the same land in the
spring of 1908, and when the writer
saw 1t on September IL it looked as
II the yield would be 20 per cent bet
ter where the vetch was plowed under
than where no cover crop was used.
Best Crop FOR Winter Cover.
Probably the winter legumes, such
as bur clover, crimson clover and
hairy yetch, are better for use as a
winter cover, especially for the pur-
pose Of improving the soil, than the
winter grains. However, the winter
grains. especially oats and barley, are
much surer than the legumes and are
equally good to hold the soil from
washing away and as winter pasture,
hit so far as they will grow it is
much better for the farmer to SOW
The winter 1egumes, for they gather
nitrogen from the air and enrich the
soil. It is an open question what win

tions crimson clover, red clover, and
the yetches may be used, but one
disadvantage of these is that in SO
manv instances the soil is not natur-
ally inocuIated for them and the first
sowing of these crops is a failure.
