Study was aimed to examine the changes in organic matter, CaCO3, pH and some nutrient concentrations in the root zone soils of pear rootstocks depending on time and rootstock variations. For this reason, “Deveci” variety grafted on OHF 333, BA29, Quince A and Quince C rootstocks were used as plant materials. To monitor the variations, soil samples were taken monthly during 8 months from each tree canopy projection areas. According to the results, it was seen that organic matter and CaCO3 content did not vary with time and rootstock but EC varied with the season, pH varied with all factors. Soil nutrient concentrations except K showed variations with time and rootstocks and/or their interactions. Available nutrients in the root zone soils of QC and QA were relatively higher than that in other rootstocks. It was found that nutrient concentrations in root zones in warmer seasons were higher than other seasons.
