Crop rotations for weed management? At first glance, it doesn’t seem possible. We know, however that in our previous videos, Dr. Anderson showed us how (1) no-till reduces weed prevalence and (2) how he verified this idea experimentally. In this third video, Dr. Anderson discusses why rotating cool season crops into our warm season rotations are so beneficial to weed control. Dr. Anderson demonstrates how through the synergistic effects of no-till combined with diverse rotations, one can reduce weed pressure by a factor of eight before the first drop of herbicide is used. We recommend you view the first two videos (“Fate of the Weed Seed in Conventional and No-Till Soil” and “Seedling Emergence in Conventional and No-Till Fields” with Dr. Anderson.
