Farmers and scientists alike over the past decade have sought to address the declining terms of farm trade (the cost.price squeeze) by increasing wheat yields in ways that will ensure both their economic and ecological survival. Nevertheless, costs have continued to increase as a proportion of the value of the product.
Many farmers have increased their wheat yields substantially and the industry as a whole is more conscious of the quality of its product.
Over the past 10 years or more there has been intense interest in, and considerable adoption of. conservation farming techniques such as minimum tillage, residue retention, cultivation on the contour, diverse rotations and tree planting.
Yet in many places salinity has increased, soil erosion has continued, herbicide resistant grasses have appeared and soil fertility has possibly declined.
