Some regularities of the content and profile distribution of trace elements in the northern and southern chernozems are presented. Chernozems of the north zone contain more trace elements, than in the south of Moldova. Also loamy-clayey chernozems are richer in copper, zinc and cobalt. The correlation coefficients showed the existence of relationship between the content of cobalt, nickel, copper, zinc, on the one hand, and the content of silt and humus, on the other. No correlation was found between cobalt and silt in chernozems. The total arable area by the degree of assurance "low" and "very low" of Mn, Zn and Cu is 32- 56% from agricultural land fond.
