It is thought that sandy soils are more likely to have this condition as the particles have a relatively lower surface area than other soil materials.
The breakdown of organic matter causes water repellent issues, but it is the type of organic matter rather than the total soil carbon that creates water repellency.
Localised dry spots resulting in plant stress or patchy germination. Waterflows develop preferential pathways – this can lead to greater infiltration through the profile, taking water away from the root zone. Runoff – This can cause loss of nutrients and soil erosion.
