Abstract

Forest trees, especially ones growing in the arid and semi arid regions, have a significant impact on the soil under and outside the tree crown and function of these ecosystems. Given that the study of relation between the trees and soil is one of the key factors in the forest management and planning, this study was conducted to investigate the crown effect of Persian Oak (Quercus brantii) high trees on some soil physical and chemical properties (Organic matter (OM), Electrical conductivity (EC), Bulk density (BD), pH, Nitrogen (N), Phosphorous (P), Potassium (K)) in the Dalab canyon forests of Ilam, Iran. By random transect method of sampling, 10 trees were select and soil samples were taken from two 0-15cm and 15-30cm depths, under and outside the crown of tree. Results show that Q.brantii significantly reduces the soil pH and BD in tow depths, increases the P, N (0-15cm) and K (15-30cm) in the beneath of tree crown in compared to outside of it. Increase of OM in tow depths and from beneath and outside of tree crown revealed a non significant difference. Generally it can be said that Q.brantii has been shown to improve physical and chemical properties of soil.
