- Virginia No-Till Fact Sheet Series Number Five: Understanding Ammonia Volatilization from FertilizersThomason, Wade E.; Woodward, Timothy; Alley, Marcus M. (2908-1404/SPES-264, 2020-09-29)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 Three: Manure InjectionMaguire, Rory O.; Woodward, Timothy (Virginia Cooperative Extension, 2019-08-30)Discusses the use and benefits of soil injectors to get manure below soil surface in no-till crop fields.
- Virginia No-Till Fact Sheet Series Number Two: Nitrogen Fertilizer Injection in No-Till SystemsWoodward, Timothy; Alley, Marcus M.; Thomason, Wade E. (Virginia Cooperative Extension, 2020-09-22)Discusses the benefits and drawbacks to injecting nitrogen fertilizers below soil surface in no-till crop fields.
- Virginia No-Till Fact Sheet Series. Number Five, Understanding Ammonia Volatilization from FertilizersThomason, Wade E.; Alley, Marcus M.; Woodward, Timothy (Virginia Cooperative Extension, 2009-08-27)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. This publication reviews the number of factors that influence the occurrence and/or rate of ammonia volatilization.
- Virginia No-Till Fact Sheet Series. Number Five, Understanding Ammonia Volatilization from FertilizersThomason, Wade E.; Alley, Marcus M.; Woodward, Timothy (Virginia Cooperative Extension, 2015-09-25)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. This publication reviews the number of factors that influence the occurrence and/or rate of ammonia volatilization.
- Virginia No-Till Fact Sheet Series. Number Six, Nitrogen Fertilizer Sources and PropertiesAlley, Marcus M.; Thomason, Wade E.; Woodward, Timothy (Virginia Cooperative Extension, 2009-08-27)The most commonly available nitrogen fertilizer sources used in Virginia are urea, liquid urea-ammonium nitrate (UAN) solution, and ammonium sulfate. Ammonium nitrate is also available in some areas but its use is low relative to urea and UAN solution. Understanding the properties of these fertilizers enables managers to make better decisions as to the most effective way to use these fertilizers as well as to make economic comparisons.
- Virginia No-Till Fact Sheet Series. Number Six, Nitrogen Fertilizer Sources and PropertiesAlley, Marcus M.; Thomason, Wade E.; Woodward, Timothy (Virginia Cooperative Extension, 2018-11-16)Discusses nitrogen fertilizers used in Virginia, their chemical properties, and costs.
