"WebThe soil pH test indicates if lime is needed. The lime requirement test determines how much lime is needed. Lime rates in eastern Oregon are much lower than in western Oregon, typically 500 to 1,500 lb/acre compared to 2,000 to 6,000 lb/acre. The lower rates reflect sandy soil or a low cation exchange capacity (CEC). " - Soil absorption ratio
