three bushels per acre, applied after the plants were up, and when wet,
produced a great crop. It should be applied only once in two years, or
in very small quantities every year. Applied as a top-dressing, it will
do no good until a considerable quantity of rain has fallen upon it. If
it be applied in the spring, and the summer prove a dry one, its
greatest effect will be felt the next season. Its most marked effects
are on poor soils; on land already rich it seems to produce but little
effect; on dry, sandy or gravelly soils, it will increase a clover crop
from one fourth to two thirds; sowed among clover and immediately plowed
in, it acts powerfully. Plants of large leaves feel its influence much
more than those with small ones, hence its excellence on clover,
potatoes, and vines. Some soils contain enough plaster already: the
farmer must determine by analysis or experiment. On the compost heap it
is valuable in small quantities; it is also useful on all long, coarse,
or fresh manures of the previous winter. Seeds rolled in it before
planting vegetate sooner and stronger. Mixed with an equal quantity of
ashes and a little lime, and applied to any crop immediately after
hoeing, or when just coming up, it adds materially to its growth. It is
better to apply it twice--on first coming up, and immediately after
first hoeing; small quantities are best;--it will ten times repay the
cost and labor. Upland pastures and meadows, except clay soils, are
greatly benefited by it. A time-saving method of sowing plaster on
fields of grass or grain, is to sow out of a wagon driven slowly through
the field, the driver being guided by his former tracks, while two men
sow out of the wagon. It is customary to put plaster and ashes, mixed,
around the hills of corn, or throw it upon the plants. Sown on the field
of hoed or hill crops, its effects are much greater than when only put
on the hill. It should be sown equally over the whole ground.
HARROWING.
The very liberal use of the harrow is one of the principal requisites of
successful farming. No other single tool does so much to pulverize the
soil, as the harrow. A full crop can only be raised on a fine mellow
soil. Seeds planted in soil left coarse and uneven, will vegetate
unevenly, grow unequally, ripen at different times, and produce unequal
quantities. Many farmers insist that it is a mere notion, without
reason, to harrow land four or five times, and roll it once or twice.
