Description:
An agricultural problem to which little attention has been directed is the relation of the supply of combined sulphuric acid in the soil to the growth of crops. Field experiments upon the value of gypsum and sulphate of iron have been made, and artificial manures containing sulphates are constantly being used, but the specific effect of the combined sulphuric acid in these materials seems never to have been sufficiently investigated. Indeed, any useful effect produced by gypsum has been ascribed to indirect action, e.g., the liberation of other constituents from insoluble soil compounds.
