Organic Agriculture April 04, 2018 Print Friendly and PDF

This webinar by Sam Wortman of the University of Nebraska Lincoln and Daniel Humburg of South Dakota State University took place on March 29, 2018.

About the Webinar

Small grits propelled by compressed air can be used to abrade weed seedlings within crop rows. This non-chemical weed management tactic is called abrasive weeding, and our research team has been developing new grit application technologies, exploring multifunctional grit sources, and studying effects of air-propelled grits on a diversity of weeds and crops throughout the Midwest. In this webinar, we will present results from over three years of research and development, and discuss opportunities for maximizing weed control, crop nutrition and yield, and profitability with abrasive weeding. eOrganic hosted an introductory webinar about this topic in 2015, available here, and this presentation will add new information.eOrganic also published an article and video about abrasive weeding, available here.
