The principle of quantitative spectral analysis was discussed and extented. For Cu 3274, Ni 3414, Co 3435, V 3184 and Pd 3421, the formula c = a.i. could be used; for Ag 3280, Lomakin's formula c = a.i mmust be used. Densities of spectral lines were always measured by using Schuffelen's formula. Except for one constant Schuffelen's formula was identical with the transformation formula of Seidel.The contents of minor elements (Cu, Ni, Co, V, Cr) in sandy soils were lower than in clayey soils. Correlation coefficients for various elements were significant. In sandy soils no correlations were found between Co and the other elements. In clayey soils there were no correlations between (Co, Cu), (Cu, V) and (Cu, Cr).
