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

ABSTRACT

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.

Key Words: ion movement in soil aggregates
