Growers need not use high rates of clay or expensive incorporation methods when claying non-wetting soils to improve yields, new Western Australian research suggests... Dr Davies said that in the latest trials, wheat yields improved by at least 0.2t/ha when growing season rainfall was at least 300mm and low rates of clay were incorporated to a shallow depth at sites including Meckering, Bolgart, Badgingarra, Binnu and Balla... Dr Davies said when moderate (150-300t/ha of clay-rich subsoil) and high rates of clay (300t/ha or more of clay-rich subsoil) were incorporated to a shallow depth, there was little additional yield advantage when compared to the lower clay rates...
