Abstract

The following work was planned to investigate the possibilities of changes of the lime requirement of acid soils when the moisture content of these soils is materially altered. Then, when changes were observed, a study of the relationships of the differences in the lime requirement, with those of the true acidity, expressed as hydrogen ion concentration, and those of the solubilities of the two soil elements, iron and aluminum, which seem to be partially responsible for this acidity, was conducted. Finally, an endeavor was made to correlate the variations in the crop -producing power of two of the soils with those produced in the above properties and constituents when the soils were air- dried previous to the planting of crops.
