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 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.
