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.

Explanation of Soil Tests
Your Soil Test Report and related Soil Test Notes referred to on a report will help you assess your plant’s need for fertilizer and lime.

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.

Laboratory Procedures: Virginia Tech Soil Testing Laboratory
The procedures for soil analysis used in the Soil Testing Laboratory were established in the early 1950s. A routine test, consisting of eleven separate analyses, is performed on all samples.

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.

Soil Sampling Instructions for the Farm
Correctly collecting a soil sample is one of the most important steps in a soil testing program! The reliability of a soil test can be no better than the sample submitted. For results that can be depended on, it is vitally important to take samples that accurately represent the soil in your fields. When one considers that a one pound soil sample must adequately represent millions of pounds of soil in the area being sampled, the importance of doing a good job of sampling becomes apparent.
