Acid soil limits crop yields on many Virginia farms. With only a few exceptions, the climate in Virginia causes unlimed soils to be moderately to strongly acidic. This soil acidity can be directly toxic to plants but more often; it reduces the plants' efficiency at nutrient utilization, especially phosphorus (P), potassium (K), and nitrogen (N). Proper management of soil acidity is the foundation of efficient soil fertility management in Virginia.
