Abstract
Increased costs of fertilizers that rely on petroleum products coupled with increased pest control and transportation costs has prompted more management practices that can make use of local waste products and utilize cover crops to reduce purchased inputs. A burgeoning wine industry could benefit from organic production techniques; however, their effects on vine growth and grape quality have not been explored in New Mexico. Alternative vineyard floor management systems were evaluated for organic grape production at the Alcalde Sustainable Agriculture Science Center in Alcalde, NM, from 2003 to 2006. Grape yield and vegetative biomass were compared between plants grown with and without compost and cover crop. Soil and leaf tissue analyses were performed yearly to monitor changes in soil fertility and chemistry. Addition of compost to vineyard soils provided adequate mineral nutrition, with the exception of plant available potassium; though vegetative growth may have been excessive. A combination of cover cropping and compost addition supported adequate grape yield; however, soil and plant mineral nutrition were varied. The use of cover crops in vineyards must be carefully managed to avoid mineral nutrition competition and to obtain consistent effects.
