Mineral nutrient contents in soils and ¢¥Fuji¢¥ apple leaves were analyzed to compare three experimental groups, which were consisted of orchards located near roadside, near industrial area, and away from roadside or industrial area around Chungju Lake. There was no significant difference between three groups in pH level, contents of organic matter, available phosphorus, exchangeable cations such as potassium, calcium, and magnesium in soils, and macronutrient contents in apple leaves. In the top soil of orchards away from roadside or industrial area, average contents of heavy metal such as Cu, Zn, Cd, Pb, and Cr were 5.6, 13.7, 0.21, 3.7, and 0.68 §·¡¤§¸^(-1), respectively. Heavy metal contents in orchard soils near roadside were much higher than those away from roadside or industrial area, and those near industrial area were slightly higher compared with those away from roadside or industrial areas. However, there was no difference in their contents of apple leaves among three groups. In general, pH level, organic matter and mineral nutrient contents were much less in sub soils(15-30§¯ depth) than in top soils(0-15§¯ depth) in all three groups.
