be advantageously employed:
phosphatic guano, or mixtures of basic slag and superphosphate, or bone
meal and superphosphate; or basic slag may be applied alone on land
deficient in lime.
Four pounds of kainit may also take the place of one pound of sulphate
of potash in the suggested mixtures mentioned below.
Where dung is recommended, twenty to twenty-five loads per acre is
meant; larger quantities are frequently applied, but these are
uneconomical and much less efficient than more moderate amounts
supplemented with artificial fertilisers.
All the manures should be worked into the soil before sowing or planting
out, except the nitrate of soda, which is best applied separately to the
growing plants, preferably in small doses at intervals of two to four
weeks.
=In all cases the quantities of artificials named are intended for use
on one square rod or pole of ground.=
PEAS AND BEANS.--These leguminous plants are able to obtain all the
nitrogen they need from the air. They should, however, be amply supplied
with potash and phosphates, a good dressing being:--
2-3/4 to 3-1/2 lb. superphosphate
3/4 lb. sulphate of potash
DWARF BEANS are sometimes benefited by the addition of 1/2-lb. to 1 lb.
of nitrate of soda.
ASPARAGUS.
A dressing of dung
2 lb. nitrate of soda
3-1/2 to 4 lb. superphosphate
3 lb kainit
The kainit contains a considerable amount of salt, which is of value to
this crop.
BEET.--For a fine crop a moderate amount of well-decayed dung applied in
autumn is almost essential, as well as 3 to 4 lb. of superphosphate per
square rod in spring. On land previously dressed with dung for a former
crop, the following may be used, especially on the lighter class of
soils:--
1-1/2 lb. nitrate of soda when the plants are well
up, and a similar amount a fortnight
after singling
4 to 5 lb. superphosphate
4 lb. kainit
BROCCOLI AND CAULIFLOWER.
=With dung=.
2 to 3 lb. nitrate of soda
2 to 3 lb. superphosphate
3/4 lb. sulphate of potash
=Without dung=.
4 to 5 lb. nitrate of soda
4 to 5 lb. superphosphate
3/4 lb. sulphate of potash
CABBAGE, KALE, AND BRUSSELS SPROUTS.--These Brassicas require
considerable quantities of nitrogen and phosphates. For spring Cabbage
planted in autumn, land well dunged for the previous crop gives good
results with the addition of the artificials mentioned below: for the
autumn crop, dung should be applied before planting out in the
