For enterprises with old machinery, the adoption of a reduced-tillage system typically requires the replacement of outdated seeders with newer units designed to accommodate the technology, this can be prohibitively expensive for small enterprises or family farms (USDA, 2010a).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.
