MICROBIOLOGICAL STUDIES OF APPALACHIAN PODSOL SOILS: IV. THE DECOMPOSITION OF GLUCOSE IN SOILS PREVIOUSLY TREATED WITH AMENDMENTS

Abstract

A study has been made of the decomposition of glucose in two cultivated podsol soils that had previously been treated with alkaline amendments. Limestone increased, and sodium carbonate decreased, the amount of carbon dioxide produced from the control samples; limestone increased the rate of evolution both in control samples and in samples receiving glucose. The total amount of carbon dioxide produced was increased by limestone in combination with sodium carbonate but not by limestone alone. The numbers of heterotrophic bacteria developing with glucose were stimulated by limestone.
