Abstract
Despite interests among Australian vineyard managers, the effects of using mulch as a management tool have not been adequately quantified. This article reports results of a three-year field trial using composted mulch over six vineyards in central NSW, Australia. Yield increases (∼1 t/ha) from mulch were found only in the low yielding areas and under a high mulch rate (153 m3/ha). Mulch also significantly increased berry potassium and pH. The yield increases were attributed to improved soil water and soil temperature conditions of the mulched soil. The research provides better guidelines for mulch use and demonstrates the potential of reducing spatial variability of yield in vineyards.
