The rood Supply of Salts from the So«.-Besides se- curing from the soil its water supply, the plant must secure in the same way all of its ash constituents, and usually all of its nitrogen, as soluble salts. The salts furnishing food are such well-known food ingredients, or constituents of fertilizers, as potash compounds. eed from the tu- 'â bacteria. phosphates, nitrates, etc. The various mineral elements generally necessary for the plant are potassium, phos- phorus, sulfur, calcium, magnesium, and iron in small quantities.

One or more of the above elements may be left out in certain cases to be compared with one in which all are present, and it will then be found that growth and development will soon be arrested where even one necessary element is entirely absent.
