Description
Soil water repellence, derived from the accumulation of hydrophobic organic compounds, is a constraint to crop and pasture production worldwide predominantly in sandy soils. Inhibited water infiltration, unstable wetting, and preferential flow are key hydrologic issues in water-repellent soil which adversely affect plant germination and establishment. However, despite the general understanding that soil water repellence can reduce soil nutrient bioavailability due to the prevalence of dry topsoil, the implications of water-repellent topsoil for plant growth and nutrition per se are unclear.
