A comparative study of the most widely spread methods for soil sample preparation for determination of Fe, Mn, Cu and Zn was carried out. It was found out that the extent of extraction of the studied elements is different and depends on the method of sample preparation and the soil type. In all cases the method of soil sample preparation is dominating. The determination of total content of Fe and Mn in all cases demands the usage of fluoride hydroxide acid and more special work condition, while at determining that of Cu and Zn this is not necessary. The evaluation of the borders of application of the methods for sample preparation depends on the purposes of the study and demands fractioning of the soil and determining the distribution of the elements in the different fractions. This would enable selection of the most suitable for the concrete purpose method connected with the least losses of time and money.
