Subsoil constraints are major limiting factors in crop production in many soils of southern
Australia. A field study examined effects of deep incorporation of organic and inorganic …

Perennial ryegrass–white clover swards were irrigated for 3 years every 50, 80 and 120 mm
of crop evapotranspiration minus rainfall (ETc–R) and water ponded on the soil surface for …

Broadacre, irrigated cotton production in Australia is reliant on landforming to optimise water-
use efficiency during the growing season. A side-effect of landforming, or “cut” and “fill” …

Red-brown earths (Red Sodosols and Red Chromosols) are the dominant soil type used for
irrigated forage production in northern Victoria. However, these soils have dense, clay …

Subsoils are often exposed during landforming for flood irrigation. Pasture growth on subsoil
of red-brown earth soils is generally poor. Two ungrazed experiments were conducted on …

The whole farm financial effects of laser land forming were analysed using a two stage
modelling procedure. In the first stage, linear programming models of representative …

Os efeitos de diferentes sistemas de manejo sobre a recuperação da produtividade de um
solo submetido à erosão simulada foram avaliados mediante parâmetros químicos do solo …
