THE EFFECT OF TOPOGRAPHICAL MODIFICATION OF HILLSIDE APPLE ORCHARDS ON THE PHYSICAL AND CHEMICAL CHARACTERISTICS OF THE SOIL

M. Iancu, M. Negoita, I. Neamtu
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.
