Mineral Surfaces as Agents of Environmental Proteolysis: Mechanisms and Controls

Creator:

Chacon, Stephany S.

Abstract:

The bottleneck in the turnover of soil organic matter (SOM) is the conversion of large molecular compounds into smaller compounds that can be transported through a cell membrane of a microbe for processing. Once inside the cell, organic compounds can be converted into biomass or be respired. The microbial depolymerization...

AN ABSTRACT OF THE DISSERTATION OF Stephany S. Chacon for
Mechanisms of Organic Matter Accumulation and Feedbacks on Pore Space in Ferralsols/Oxisols Containing High Carbon Stocks

Creator:

Martinez, Pedro

Abstract:

Deeply weathered soils in tropical rainforests and savannas are classified as Ferralsols according to the World References Bases for Soil Resources (WRB). Ferralsols are most nearly akin to the Oxisols order defined in the US Soil Taxonomy. The acidity, low cation exchange capacity, and strong phosphorus retention by the oxidic...
