  • Biomass shifts and suppresses weed populations under conservation agriculture
    Mulvaney, Michael J.; Wood, C. Wesley; Price, A. J. (2011)
    Shifting tillage practices to Conservation Agriculture has numerous effects on both the soil and weed populations found in productive areas. The purpose of this research is to "quantify weed suppression of a summer cover crop and organic mulches under no-till collard (Brassica oleracea L.) production during conversion to CA" (authors). The authors examined weed populations, SOC, and collard yield over the course of three years.
  • Cover crop residue and organic mulches provide weed control during limited-input no-till collard production
    Mulvaney, Michael J.; Price, A. J.; Wood, C. Wesley (Taylor & Francis Group, LLC, 2011)
    Conservation tillage is an effective means to suppress weeds, improve soil quality, and thus enhance food security. However, limited-input producers are reluctant to adopt these practices because of inadequate weed suppression without herbicide use. The purpose of this study was to demonstrate that effective weed control and stable collard yields can be achieved through high-biomass producing cover crops with organic mulches. This system was employed for three consecutive years (2005 - 2008) using forage soybean summer cover crop and mimosa, lespedeza, wheat straw, and a no-mulch control. Mulch use was successful in suppressing broadleaf and sedge weeds over the course of the experiment and demonstrated grass weed suppression after three years. Collard yields were not affected by mulch use and averaged 17,863 kg/ha. The results of this study strongly suggest that limited-input producers may incorporate mulch use in conservation tillage systems without affecting crop yields.
