Vine medication – the benefits of undervine cover cropping
Management of the vineyard’s undervine zone has generally involved the removal of all vegetation that might generate competition for water and nutrients. However, as producers aim to advance the sustainability of vineyard management, improving the treatment of soil in the undervine zone is critical. To address this issue, with funding from Wine Australia, a three-year trial investigated the capacity for cover crops sown undervine to reduce the need for weed control while improving soil health and productivity, but without adverse impacts on wine quality. The overwhelming outcome of the trial was evidence that sowing self-regenerating early maturing Medicago spp. (pasture medics), with or without annual ryegrass, reduced weed growth and either maintained or improved yields and financial gross margins compared to the herbicide control or straw mulch.
