Irrigated fields under CA
Irrigated fields under conservation agriculture (CA) at CIMMYT's CENEB experiment station near Ciudad Obregón, Sonora, northern Mexico. The raised beds where the crop is planted are clearly visible, as are the furrows where water flows and is distributed more efficiently. Permanent raised beds have improved soil structure and require less irrigation water than conventional tillage and planting on the flat.
