Sources of Lime for Acid Soils in Virginia
Acid soil limits crop yields on many Virginia farms. This soil acidity can be directly toxic to plants, but more often it reduces the plants' efficiency at nutrient utilization.

Soil Test Note #2 - Field Crops
Most Virginia soils are acidic and require lime applications at three- to five-year intervals. Maintaining the correct soil pH has several benefits, such as encouraging healthy root development and making sure nutrients in the soil are available to the plant. For example, low pH can cause aluminum toxicity and can decrease phosphorus availability.

Importance of Farm Phosphorus Mass Balance and Management Options
Phosphorus is a naturally occurring element that is one of 16 elements essential for plant growth and animal health. Research has documented that applying phosphorus in fertilizers or manure increases crop growth and yield on soils that are below critical agronomic levels, as measured during routine soil testing. Although the economic benefits of phosphorus fertilization on crop production are well-documented, too much of a good thing can be detrimental to the environment. Excessive soil phosphorus is a potential threat to water quality.
