Abstract: The aim of this study is to understand the soil status of Yantai apple orchard and provide the basis for the management of fertilization. Distribution characteristics of soil pH and organic matter were studied by analyzed from 3354 soil samples in Yantai apple production area, and then the relationship between soil pH, organic matter and soil nutrients were analyzed. The results showed that: the mean soil pH in Yantai apple production area was 5.21, and about 31.88% of the soil samples had pH 5.51-6.50. The percentage of samples which soil pH was below 5.5 accounted for 56.46%. The mean soil organic matter in Yantai apple production area was 9.78 g/kg, and about 58.31% of the samples were less than 10.00 g/kg. The soil pH had significantly negative correlation with available Zn and Mn, and significantly positive correlation with soil organic matter and total N content. The soil organic matter had significantly positive correlation with all soil nutrients except available P, and the correlation between soil organic matter and available P was positive but not significantly. Therefore, preventing soil acidification and enhancing the level of organic matter were the urgent task to achieve the goal of sustainable development of fruit industry in Yantai.
