Soil testing methods for determination of exchangeable and pseudototal forms of nutrients and elements that are currently used in the Czech Republic were compared. Results of different methods were investigated by parallel analysis of forest soil samples. The aim of the analyses was to determine exchangeable content of calcium, potassium, magnesium, aluminium, iron, manganese, sodium (Ca, K, Mg, Al, Fe, Mn a Na) and pseudototal content of calcium, potassium, magnesium, phosphorus, aluminium, iron, manganese, lead and zinc (Ca, K, Mg, P, Al, Fe, Mn, Pb, Zn). Hundred forest soil samples were analysed for the study using Mehlich III extracting solution, barium chloride, aqua regia and nitric acid extraction. Statistical parameters of the data and differences between methods were determined. The extraction methods were evaluated based on a correlation analysis of the element concentration. For Ca, K, Mg and Mn the results with Mehlich III extracting solution were highly correlated with the barium chloride. Aqua regia was highly correlated with nitric acid in case of Ca, P, Mn and Pb. The largest concentrations in general were obtained mostly with aqua regia. For proved correlating methods Single linear model of regression analysis could be used for recalculations between individual pairs of methods.
