Demonstration of Different Cover Crops

On April 28, 2004, Dr. Ali Fares held a field demonstration at Waialua, on the North Shore of Oahu. The goal of the field day was to share the results of his team's research using grass cover crops (Oats, Sunn Hemp and Sudex) as a means to manage nutrients in bare ground fallow cropping systems. The team is also examining the effects of the cover crops on weed control. University of Hawaii, Crop Care Hawaii, Waialua High School, and Pioneer Hi-Bred International, Inc. collaborated on the project funded by the U. S. Environmental Protection Agency and the Hawaii State Department of Health, Clean Water Branch under Section 319(h) of the Clean Water Act and University of Hawaii, College of Tropical Agriculture and Human and Resources, Sustainable Agriculture Research and Education.
