The first study is laboratory research in which strong salt soil extracts were analyzed using inductively coupled argon plasma atomic emission spectroscopy both with and without argon humidification compared with conventional laboratory testmethods. Twenty-five soils were extracted with three strong salt soil extracting solutions and analyzed by three methods. The second part is laboratory research comparing soil extraction parameters for aluminum, manganese, calcium, and magnesium determinations. Soil extracts were analyzed using inductively coupled argon plasma atomic emission spectroscopy. Two soils were studied using four potassium chloride concentrations, four extraction times, and three soil:solution ratios. Both parts are presented in a format suitable for publication in Communications in Soil Science and Plant Analysis. Laboratory data for both studies are in the appendixes.application/pdfCopyright is held by the author who has granted the Oklahoma State University Library the non-exclusive right to share this material in its institutional repository.
