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.

Corn Planting Dates in the Piedmont and Valley Regions of Virginia: How Early is Early?
Early-planted corn generally produces higher yields than later-planted corn due to improved utilization of sunlight during the long days of June and July, assuming moisture is adequate. Also, silage harvest can begin earlier and drying costs are reduced for grain corn; and earlier harvest enables growers to begin preparation for the fall seeding of small grain crops.

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.

Virginia Cover Crops Fact Sheet Series No. 1: Beneficial Uses of Cover Crops
The general purpose of a cover crop is to improve the soil, the broader environment, or other crops in rotation, not for direct harvest. Cover crops, depending on which are selected, are capable of providing many diverse assets. This publication provides a short description of these main benefits.

Virginia Cover Crops Fact Sheet Series No. 2: Cover Crop Performance Evaluation in Field and Controlled Studies
Cover crops increase soil organic matter, reduce erosion, suppress weeds, forage for nutrients, and reduce fertilizer costs (Clark, 2007). Cover crop species vary greatly and provide varied benefits. Performance evaluation of cover crop species and mixtures is needed in Virginia.

Consider Your Whole System: Nitrogen and Sulfur Leaching Potential in Virginia
Early summer often means locally heavy and sporadic rainfall as thunderstorms deliver intense rains, and 2018 appears to be no different with many areas in eastern Virginia receiving 3+ inches of rain in a few days (Figure 1). These storms also often coincide with the timing of sidedress nitrogen (N) and sulfur (S) applications on corn. While some rainfall after sidedress is very beneficial to facilitate N movement into soil, heavy rain (2+ inches) often leaves us wondering how much, if any, of that recently-applied N remains and if additional N is needed.
