|Virginia No-Till Fact Sheet Series Number Five - Understanding Ammonia Volatilization from Fertilizers||
Loss of nitrogen (N) as ammonia gas (NH3) is known as volatilization. While volatilization directly from soil can occur, such loss is generally relatively small compared to the amount that can be lost from fertilizers. Volatilization losses can be significant with granular urea and urea-ammonium nitrate (UAN) sources, but the amount of loss varies greatly depending on placement of the fertilizer, soil pH, soil texture, and climatic conditions after application.

|Virginia No-Till Fact Sheet Series Number Two: Nitrogen Fertilizer Injection in No-Till Systems||
Liquid nitrogen fertilizers have typically been surface applied. This method of application places the fertilizer where the urea nitrogen component of the solution is susceptible to volatilization losses.

|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.
