f the roots of
the turnip. And this is the secret of its great value for this crop. It
increases the growth of the young plant, developing the formation of the
roots, and when the turnip once gets full possession of the soil, it
appropriates all the plant-food it can find. A turnip-crop grown with
superphosphate, can get from the soil much more nitrogen than a crop of
wheat. The turnip-crop, when supplied with superphosphate, is a good
"scavenger." It will gather up and organize into good food the refuse
plant-food left in the soil. It is to the surface soil, what clover is
to the subsoil. To the market gardener, or to a farmer who manures
heavily common turnips drilled in with superphosphate will prove a
valuable crop. On such land no other manure will be needed. I cannot too
earnestly recommend the use of superphosphate as a manure for turnips.

For Swede turnips or ruta-bagas, it will usually be necessary, in order
to secure a maximum crop, to use a manure which, in addition to
superphosphate, contains available nitrogen. A good dressing of rich,
well-rotted manure, spread on the land, and plowed under, and then 300
lbs. of superphosphate drilled in with the seed, would be likely to give
a good crop.

In the absence of manure, there is probably nothing better for the
ruta-bagas than 300 lbs. of so-called "rectified" Peruvian guano, that
is, guano treated with sulphuric acid, to render the phosphates soluble.
Such a guano is guaranteed to contain 10 per cent of ammonia, and 10 per
cent of soluble phosphoric acid, and would be a good dressing for Swede
turnips.

The best way to use guano for turnips is to sow it broadcast on the
land, and harrow it in, and then either drill in the turnip-seed on the
flat, or on ridges. The latter is decidedly the better plan, provided
you have the necessary implements to do the work expeditiously. A double
mould-board plow will ridge up four acres a day, and the guano being
previously sown on the surface, will be turned up with the mellow
surface-soil into the ridge, where the seed is to be sown. The young
plants get hold of it and grow so rapidly as to be soon out of danger
from the turnip-beetle.

MANURES FOR MANGEL-WURZEL OR SUGAR-BEETS.

When sugar-beets are grown for feeding to stock, there is probably
little or no difference in the manurial requirements of sugar-beets and
mangel-wurzel. Our object is to get as large a growth as possible
consistent with quality.
