A Method for Investigating the Chemical Heterogeneity of Soil Material within Natural Soil Aggregates1

A procedure is described to study chemical heterogeneity of soil material within natural aggregates. Soil from aggregate surfaces is separated from interior material by a freezing and thawing process. Results for two soils indicate higher concentrations of water-soluble elements in the exterior soil material, whereas, the interior material contained about equal or slightly greater amounts of extractable elements than the exterior material.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
