| Abstract |
Two field experiments are being conducted in southwestern Arizona to investigate the potential of reducing the salt load in irrigation return flow by decreased leaching. Three leaching treatments of 5, 10, and 20%, replicated nine times for citris and five times for alfalfa, were established and compared with conventional flood irrigation management. Results on citrus indicate that leaching percentages of 8, 11, and 22 were achieved, compared to 47% on the border flood check. The best estimate of the annual evapotranspiration of citrus is 1400 mm. Reduced leaching has not adversely affected fruit quantity or quality. If leaching were reduced to 20%, the volume of drainage from the 3000 ha of citrus in the district would be decreased. |
