One-off deep cultivation can reduce the severity of soil water repellence.
Soil water repellence is caused by an accumulation of waxy organic matter in the soil surface. It is worse in sandy textured topsoils.
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
Banding soil wetting agents with the seed can improve establishment on water repellent soils often having the same effect as seed placement on the furrow surface.
On water-repellent loamy gravels (forest gravels) banded soil wetting agents and one-off deep tillage can significantly improve crop establishment, growth and grain yield.
