early
part of the year.
=With dung=.
2 to 3 lb. nitrate of soda
4 to 5 lb. superphosphate
3/4 lb. sulphate of potash
=Without dung.=
4 lb. nitrate of soda
5 to 6 lb. superphosphat
3/4lb. sulphate of potash
CARROT AND PARSNIP.--A good dressing of dung applied to the previous
crop is a valuable preparation where Carrots and Parsnips are to be
grown. In addition, one of the following mixtures should be used:--
(1)
3/4 lb. nitrate of soda
3 to 4 lb. superphosphate
3/4 lb. sulphate of potash
(2)
3/4 lb. nitrate of soda
2 lb. superphosphate
1 to 2 lb. basic slag
3 lb. kainit
CELERY requires the use of dung more than almost any other crop, and it
is little affected by artificial manures, except phosphates, which may
be given in the form of superphosphate at the rate of 2-1/2 to 3-1/2 lb
per square rod.
LETTUCE.
=With dung=.
3 to 4 lb. superphosphate
1/2 to 1 lb. nitrate of soda
=Without dung.=
3 to 4 lb. superphosphate
1 to 1-1/2 lb. nitrate of soda
1 lb. sulphate of potash
ONIONS never succeed without an ample supply of potash. This crop should
therefore have farmyard dung, or the special potash fertilisers in
adequate quantity.
=With dung.=
3/4 lb. nitrate of soda
4 to 5 lb. superphosphate
3/4 lb. sulphate of potash
=Without dung.=
1-1/2 to 2-1/2 lb. nitrate of soda
5 lb. superphosphate
1 lb. sulphate of potash
LEEKS require the same fertilisers as Onions, but will need little or
no nitrate if good dung is used.
POTATO.--For good yield, high quality, and freedom from disease,
Potatoes are dependent upon a good supply of potash. They do best when
supplied with a moderate amount of farmyard manure, supplemented by
suitable artificials, but can be grown on some soils with artificials
alone.
=With dung=.
3/4 lb. sulphate of ammonia
3 lb. superphosphate
3/4 lb. sulphate of potash
=Without dung=.
1-1/2 lb. sulphate of ammonia
3-1/2 lb. superphosphate
1 to 1-1/2 lb. sulphate of potash
Instead of superphosphate, a mixture of this fertiliser with an equal
amount of bone meal or basic slag may be used, and either 4 lb. of
kainit and 1 lb. of muriate of potash instead of 1 lb. of sulphate of
potash.
RHUBARB.--An annual dressing of dung is beneficial, together with 6 lb.
of basic slag, 1 lb. of sulphate of potash, and 4 lb. of nitrate of
soda, half the nitrate being applied when growth commences and the
remainder a fortnight later.
