are reduced nitrogen availability ( Billeaud and Zajicek, 1989 ), water repellency ( Gartner, 1978 ), and allelopathy ( Duryea et al., 1999 ; Still et al., 1976 ). One question that is often asked by landscapers is whether fertilizers should be
suppress weeds by either reducing resource availability ( Ngouajio and Mennan, 2005 ) or by inhibiting weed growth via allelopathy ( Reberg-Horton et al., 2005 ). Access to light, nutrients, water, and soil as affected by CC may affect weed persistence
weed density and weed seedling emergence, particularly for summer annual weeds that are responsive to temperature and light, by direct competition from cover crop biomass ( Mennan et al., 2009 ; Teasdale, 1996 ) or by allelopathy ( Barnes and Putnam
