Chemical characteristics of two forested Ultisols and two forested Inceptisols relevant to anion production and mobility
As a prelude to a basic program on soil leaching, some chemical characteristics of two forested Ultisols in eastern Tennessee and two forested Inceptisols in western Washington are discussed in relation to the production and mobility of anions. These soils were chosen in an attempt to provide a range of free iron (Fe) and aluminum (Al) contents (which are hypothesized to be related to anion adsorption) and carbon:nitrogen (C:N) ratios (which are hypothesized to be related to nitrate and bicarbonate production) for field experiments involving C, N, and anion salt additions. The Washington Inceptisols had high free Fe and Al in surface horizons and decreasing free Fe and Al levels with depth, whereas the reverse was true of the Tennessee Ultisols. The Alderwood-red alder and Tarklin (sinkhole) soils had higher N concentrations and lower C:N ratios in their surface horizons than the Alderwood-Douglas-fir and Fullerton soils, respectively, but the reverse was true of subsurface horizons. Patterns of and relationships among the above properties and pH, Bray phosphorus (No. 2); adsorbed and soluble SO/sub 4//sup 2 -/, Cl/sup -/ and NO/sub 3//sup -/; cation exchange capacity; and exchangeable cations are discussed.
