Aims:
In Western Australia, break crop options are currently limited and there is a high proportion of wheat and barley grown in rotation. Cereal crops account for 60-70% of paddocks sown in any one year, with the remaining area sown to a range of crop and pasture types including canola, lupin, clover, volunteer pasture, or left as fallow. In addition… read more
