The effectiveness of commercially available wetting agents for combating on-site soil water repellency in sandy soil (original) (raw)

Soil hydrophobicity is a prevalent issue affecting various soil types, particularly those with high sand content, leading to adverse environmental effects such as reduced crop growth and increased soil erosion. This study evaluates the effectiveness of three commercial wetting agents on ameliorating soil water repellency in sandy soils through various tests, including capillary rise and infiltration measurements. Results indicate that, contrary to expectations, these wetting agents may not only fail to improve wettability but could potentially enhance water repellency.
