Abstract
The official journal of Agricultural Sciences published by the Faculty of Agriculture, Eastern University, Chenkalady, Sri Lanka.AGRIEAST publishes research information of broad practical significance pertaining to both tropical and subtropical Agriculture.
Highlights
Soil water repellency is a reduction in the rate of wetting and retention of water in soil caused by the presence of hydrophobic coatings on soil particles
In order to confirm whether the soils under the pine forest exhibits WR, the same water drop penetration time (WDPT) test was conducted in the grass land adjacent to the study area
The severity of soil water repellency is mainly determined by the moisture content of soil
Summary
Soil water repellency is a reduction in the rate of wetting and retention of water in soil caused by the presence of hydrophobic coatings on soil particles. Numerous techniques have been developed to determine the water repellency of soil. The creation of water repellency in soils involves both physical and chemical processes. Emergence of soil water repellency (SWR) is mainly due to soil water content and the intensity of SWR is dependent on soil organic matter, texture, etc. It is modifying physical processes such as infiltration and water movement in soils. Water repellency is produced by soil organic matter and can be found in both fire and non-fire soils (DeBano 2000)
