General physical and chemical characteristics of eleven apple orchard soils derived from granite, granodiorite, diorite, arkose sandstone and shale were investigated in relation to soil profile. The results are summerized as follows: 1. Soils were mostly sandy and showed pH 4.35 to 6.75, 1.14 to 5.58 of organic matter, 0.065 to 0.209% of nitrogen. All properties decreased with depth. 2. Total exchangeable bases of surface soils were comparablly low (4.89 to 17.81me/100g, Ca>Mg>K>Na). Cation exchange capacity ranged from 7.74 to 21.72 mg/100g and base saturation percentage from 22.52 to 94.62%. 3. Phosphorus content of surface soil was very low (less than 35.5 mg/100g). The contents of potassium (7.2-79.2 mg/100g), available copper (1.0-16.9 ppm) and water soluble boron (0.18-0.72 ppm) were high in surface soil but low with depth. The content of manganese showed clear difference with pH, that is, at pH 4 to 6 water soluble manganese ranged from 0.42 to 17.8 ppm and exchangeable manganese from 9.82 to 66.38 ppm but above pH 6 the water soluble was less than 0.70 ppm and the exchangeable less than 22.25 ppm.
