What is volatilization of fertilizer?
Volatilization is the loss of applied nitrogen to the atmosphere as ammonia gas. To understand how to reduce this form of nitrogen loss, it’s important first to understand how and why it occurs.
What causes volatilization in soil?
In general, higher pH, warmer temperatures, and greater soil moisture content increase the potential for volatilization, while soil incorporation via rainfall, irrigation, or tillage after application decreases volatilization potential.
What is volatilization in plants?
(3) Volatilization is the partitioning of the contaminant into the air spaces within a plant and subsequent diffusion into the ambient air, under the assumption that ambient air is less contaminated.
What causes volatilization of nitrogen?
The process of ammonia volatilization commonly takes place when nitrogen is in an organic form known as urea. Urea may originate from animal manure, urea fertilizers and, to a lesser degree, the decay of plant materials.
What is the meaning of volatilization?
: to make volatile especially : to cause to pass off in vapor. intransitive verb. : to pass off in vapor.
How can we reduce volatilization?
Ammonia volatilization can be minimized by applying NH4-forming fertilizers in dry and cool weather and by avoiding application on warm, humid, or windy days.
What is pesticide volatilization?
Pesticide volatilization can be defined as the movement of pesticide vapors through the air. People such as farm workers and bystanders can be exposed to pesticides by breathing these vapors after an application has occurred.
What happens during volatilization?
Volatilization is the conversion of a liquid chemical into a vapor, which escapes into the atmosphere.
What is the difference between denitrification and volatilization?
De-nitrification is common in poorly drained soils. Volatilization is the loss of N through the conversion of ammonium to ammonia gas, which is released to the atmosphere. The volatilization losses increase at higher soil pH and conditions that favor evaporation (e.g. hot and windy).
Why is ammonium sulphate used as fertilizer?
Ammonium sulfate is used most commonly as an artificial fertilizer for alkaline soils. When introduced into damp soil, an ammonium ion is released. This creates a small amount of acid, which lowers the pH balance of the soil. It also contributes nitrogen, which aids in plant growth.
Which fertilizer is highly hygroscopic?
Explanation: Ammonium Chloride is a highly hygroscopic fertilizer. Hygroscopic fertilizer means the fertilizer that absorbs moisture from the atmosphere to become sticky.
