Long-term use of herbicides in the orchard acidified the soil and reduced the content of organic matter in comparison with the soil under grass. Fertilization with NPK decreased the pH and Mg content but increased the P and K levels in the soil. Soil management methods did not have a significant effect on the levels of K, P, and Mg in the soil.
