A bright clear sustainable agricultural future demands that no synthetic chemicals should be used at any stage of the grape growing, and later winemaking, processes. This can be done and is done, with yields comparable to the district average, at least at Langhorne Creek. Nutrients are supplied in part by compost, but also by growing cover crops of legumes and cereals, the former for nitrogen and the latter for organic matter. We try to minimise cultivation, and to that effect, the cover crop is rolled or slashed and thrown under vine. Sometimes the under vine row is mulched, other times it is cultivated. Fungal diseases are controlled using Ecocarb and vegetable oil. Insect pests are food for predators. The native vegetation around the vineyard provides habitats for many of them.
