| Abstract:
The physical and chemical soil properties of hillside land arrangement systems for intensive apple orchards were studied. On average, over the 0–1.0 m soil depth and the 4 treatments (crop on contour line, lower, middle or upper terrace platform) and 2 soil conditions (brown colluvial soil or slightly eroded soil), bulk density increased significantly by 1.7%, resistance to penetration increased by 15% and saturated hydraulic conductivity decreased by 31%. The soil humus content in the lower part of the terrace platform was significantly higher than the soil humus content in the middle part (44% higher), the upper part of the terrace platform (91% higher), and the contour line treatment (20% higher). The soil of the contour line treatment had a significant decrease in bulk density but a significant increase in soil physical clay content, saturated hydraulic conductivity and resistance to penetration. | |
