Title: Ion Chromatography as an Alternative to Standard Methods for Analysis of Macro-nutrients in Mehlich 1 Extracts of Unfertilized Forest Soils

Author: Fischer, Joseph B.; Miller, James H.

Date: 2004

Source: Communications in Soil Science and Plant Analysis, Vol. 35, Nos. 15 & 16, pp. 2191-2208, 2004

Publication Series: Not categorized

Description: This study evaluates ion chromatography (IC) as an alternative to atomic absorption (AA) and inductively-coupled plasma spectromctry (ICP) for analysis of potassium (K), magnesium (Mg), and calcium (Ca), and and as an alternative to antimonylmolybdate colorimetry and ICP for analysis of phosphorus (P) macro-nutrients in Mehlich 1 extracts. Soils typical of pine forests in the southeastern United States were tested. IC correlates well with AA and ICP for K and Ca, but not for Mg, unless conditions are chosen that resolve Mg from manganese (Mn). IC does not correlate very well with colorimetry for P at extract levels below 2 mg kg-1 or in extracts with high levels of dissolved organic matter complexes of aluminum (Al) and iron (Fe). ICP results for P exceed both IC and colorimetry by 3-5 mg kg-1 for all soils tested. The merits of IC relative to AA, ICP, and colorimetry for forest soil testing are discussed.

Keywords: Ion chromatography, Soil, Forest, Analysis, Mehlich 1, K, Ca, Mg, P, Colorimetry, ICP, Atomic absorption, Macro-nutrients
