The Physical Action Of Lime On Clay Soils PDF Download

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 recent investigations in the field of soil acidity have raised anew the question of the physical action of lime on the soil. A number of physical investigations have been conducted in the past, but the recent progress in certain auxiliary subjects, as colloid chemistry, has tended to depreciate the value of much of this work, and bring new problems to the front. The question may therefore be properly considered again: What is the specific effect of each form of lime on the soil, and how great is that effect? Our problem resolves itself into two parts: First, the selection of desirable methods, and second, their application. Let us first review the procedures available for the study of the colloidal characteristics of the soil, and determine wherein their merits and deficiencies lie.
