The content of 14 chemical elements was measured in the soil of ten long-term field trials located in different climatic zones of Lithuania. Soil samples were taken from the control (untreated) and anthropogenic (fertilized with mineral NPK and/or organic fertilizers, limed) treatment plots. The samples were analyzed by the AAS method and directly analyzed with X-rays upon fine grinding (for Sr). In the western zone of Lithuania the anthropogenic impact (liming with fertilizing) resulted in statistically significant increase in the content of 4 elements (B, Ni, Sr, Zn). In the eastern zone 3 elements (Cu, Co, Sr) showed significant differences. Soil contamination index was exceeded significantly (up to 2 versus the background levels) only for Sr (2.14 times) in the western zone
