Water movement in hydrophobic soils

  title={Water movement in hydrophobic soils},
  author={Stefan H Doerr and Coen J. Ritsema},
Hydrophobicity (water repellency) can reduce the affinity for soils to water such that infiltration or wetting may be delayed for periods ranging from as little as a few seconds to in excess of weeks. Soil hydrophobicity is thought to be caused primarily by a coating of long-chained hydrophobic organic molecules on individual soil particles. These substances may be released from a range of plants, decaying organic matter, soil fauna, and microorganisms either naturally or during burning… CONTINUE READING
