Chemical composition of soil solution and water

From bulk deposition, throughfall, stemflow, soil solution and outflow the electrical conductivity and the concentrations of H⁺, Al³⁺, Ca²⁺, Mg²⁺, K⁺, Na⁺, Cl^-, NH⁴⁺, NO^3-, N-org, SO₄^2-, PO₄^3- and dissolved organic carbon (DOC) are measured. The samples are analyzed by the means of ICP, HPLC, a TOC-analyzer, FIA and spectrophotometry.
