Résumé
This poster studies the adoption of conservation tillage in the state of Guanajuato over the last decade to procure baseline information for a research program aiming at developing sustainable farming practices. The key questions included were as follows: what type of practices and cropping systems do farmers use? Are they aware of conservation techniques? Have they already tried some form of conservation tillage? Are there any differences in the pattern of adoption by agro-ecological zones, by farmer's type? The results show a significant amount of partial adoption of conservation tillage techniques, although there are differences according to the agro-ecological zone, and to the type of farmer. Adoption occurred mainly where irrigation is available, and for the summer cycle. Residues are not left on the soil surface but are exported from the field or burned. The combination of no-till and removal of residues seems to oblige farmers to revert periodically to conventional tillage. (Résumé d'auteur)
