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.
