Pastures in a grazing systems experiment near Canberra were measured for pasture mass over four years and for composition in the final year to identify the effect of sowing 33% of the available land to dual-purpose crops (wheat and canola) each year. The system that included dual-purpose crops had significantly less feed on offer in February (when ewes were joined) and May (when grazing of crops commenced) compared to the pasture only system. In the final year of the experiment the proportion of weed species in the pastures of the dual-purpose cropping system was significantly higher compared to the pasture-only treatment.
