For enterprises with old machinery, the adoption of a reduced-tillage system typically requires the replacement of outdated seeders with newer units designed to accommodate the technology; this can be prohibitively expensive for small enterprises or family farms (USDA, 2010a). Moisture-saving technologies were applied on 11.7 million hectares sown to grains in 2011, or 72% of the total. This compares to 1.1 million hectares and 8% in 2003.
