The aim of this investigation was to use the cropping systems simulator APSIM to assess the impact of high levels of sodicity chlorine, electrical conductivity and boron on the growth and yield of a wheat crop (cv. Yitpi) grown in the BCG Systems Trial.
The simulation study suggests that the rate of root extension into the subsoil was dramatically slower in the presence of subsoil constraints. However, in the 2001 season, wheat yield was not limited by this factor, which reduced the use of soil moisture early in the season and thus delayed the onset of water stress during the dry grainfilling period.
