Abstract

Paralel determination of the content of mineral nitrogen (Nmin) and soluble organic nitrogen (SON), extracted from the soil with the 0.01 M CaClsolution, improves the fertilizer recommendations with nitrogen. We have developed a method for determination of the soluble organic nitrogen in the soil for this purpose. The method was accordingly verified for the analyses. It was achived by the comparison of the analytical results, which were studied through the international interlaboratory exchange programme WEPAL (Wageningen Evaluating Programme for Analytical Laboratories, Netherland). To confirm the applicability of the newly introduced and verified method, we chose an example of the fertilization attempt for the corn, which was performed in four different locations in Slovenia.
