Use of Artificial Manures in Vegetable Growing

IT is useless throwing handfuls of t some pet manure over your vege- ( table garden and expect all crops to , react immediately and with equal ] vigour. Special manures are needed j to perform special jobs. Nitrate of soda and sulphate of - ammonia, for instance, are immediate acting, but the lasting effect , depends on the amount of applica- ' tion and the nature of the crop to be manured. Whilst one good appli- ' cation may last the whole duration • of the given crop with some vege- : tables, it is necessary to make fre- < quent applications with others, i especially onions. A good, safe rule 1 is to make applications fortnightly. ] Future crops on the same ground ] will require further manurings. ; Blood and bone, dried blood, and stable manure also act immediately, but their effects are far-

V reaching. With the first-named, the blood has a forcing effect, and will act as such at once. Results from bone (which gives a warming effect), are not apparent until later on. Stable manure helps to loosen the soil quickly, and the ammonia from same will act at once. Afterwards the manure becomes humus, and will be useful for a considerable time, mainly in keeping the ground open. A good application of any of the above-mentioned manures will last out a crop, and sometimes the following one as well. -i ir-
