Vineyard Soil Management

Introduction: Soil properties

Most soils in the prime NSW Vineyard areas are of the duplex or podsolic soil type. This means they have a sandy to loamy A horizon generally around 150mm deep but sometimes to 600 mm deep, overlying a clayey B horizon layer of a red or yellow colour. Sometimes they have a sandy pale A2 horizon below the darker A1 horizon. This layer is often quite hostile being acidic, low in organic matter, very low in nutrients, and prone to periodic waterlogging. Periodic waterlogging or poor drainage is indicated by the presence of black and tan colored roundish nodules (Fe/Mn nodules).
