It is essential that the soil contains
all the elements that found in the plant itself so called natural
fertilizers and that it retains them long enough for the plant to
absorb them during its life. The chemical elements most needed by
plants and most liable to rapid exhaustion are nitrogen, phosphoric
acid (phosphorus) and potash (potassium).
There are other elements in the soil but they are used in such small
quantities that they are lost from the soil only in exceptional
circumstances.
