FAQ's-Soil Amendments to Remedy Soil pH

A: Soil pH in the Willamette Valley tends to be on the low side, rather then high. A lime application of 3 to 8 tons per acre can offer a lasting remedy to low soil pH. For lime treatments on new vineyard developements prior to planting, Powdered lime is the most affordable and is offered by many local agronomy outlets. Lime should be applied in the spring or fall so that rainfall will help incorporate the product into the soil.

If soil sampling finds your established vineyard's soils on the acidic side, applying granular lime by hand or mechanically at 3-5 tons per acre can also be very affective and affordable. OVS offers an under vine lime slurry service that is fast and affective but costly.
