Description :
The purpose of this study was to investigate the persistence of soil water repellency (SWR) in 10 forestry sites under different plant species in North of Iran at Guilan province. The soils examined in this study include a broad range of textures, organic matter contents and pH levels. In the field, the actual water repellency was determined using the Water Drop Penetration Time Test (WDPT) but the same test was used to determine the potential water repellency after drying process for several days at 25 °C in the laboratory. Sampling was performed within 2 seasons (Autumn and Summer) and actual water repellency was only observed in forests in the Summer. Field observations imply that SWR is not a static soil property and could be observed in field when soil becomes so dry. The results show that soil organic matter content, texture and pH are important factors for developing SWR in soil.
