Publisher's Synopsis
Excerpt from The Physical Action of Lime on Clay Soils: A Thesis Presented to the Faculty of the Graduate School of Cornell University for the Degree of Doctor of Philosophy
The classical investigations of Ammon and of von Dob'eneck belong to the first type. They conducted the saturated vapor through a U-tube or some other suitable vessel containing the soil, until equilibrium had been reached. Both men were concerned with the adsorptive power of the various soil constituents, and so carefully was their work conducted, that it remains today our most valuable contribution to the subject.
