Take a minute to study the layout depicted in the cartoon schematic of the vineyard at Los Lunas ASC. The mulch treatments are: wood chip mulch, pecan shells and herbicide treated soil strip (bare). All treatments are located under the trellis and are ~ 3 ft. wide. The effects of the designated plots and will be evaluated over the next 3 years. Some dependent variables we will investigate, measure and evaluate are: soil moisture, soil temperature, vine performance (dormant pruning weights, vine phenology or seasonal development, yields and berry composition at harvest: titratable acidity, soluble solids, pH and YAN: yeast assimilable nitrogen). The two main cultivars to be established into the different mulch plots are Touriga Nacional, a traditional port variety, and Refosco, a red grape typically grown in Northern Italy. I welcome your comments.
