Abstract
To study the effects of soil wettability and wetting agents on seed germination and establishment, three substrates (naturally occurring non—wettable soil, and a wettable quartz sand) were placed in small plastic containers and received applications of wetting agent in liquid, wetting agent on perlite, and no treatment as a control. The containers were seeded to wimmera ryegrass and were placed both on a 30° slope and on the level in a controlled temperature chamber (70°F). Seed placed on a non—wettable soil which received no wetting agent treatment failed to germinate in those containers placed on the slope. Good germination occurred on soil which was treated with a wetting agent and on wettable sand. The same are primarily due to water relations; water ran off the sloping non—wettable soils. Wetting agent treatment on the wettable sand reduced both germination and establishment of the tested plants.
