True or False: Volatilization generally results in a loss of nitrogen to the atmosphere.

Volatilization is the process where a substance changes from a liquid or solid state into a gas. In the context of nitrogen in agriculture, volatilization primarily refers to the loss of ammonia (NH3) gas into the atmosphere from fertilizers, particularly urea and ammonium-based fertilizers. This process typically occurs when these fertilizers are applied to the soil surface and can be influenced by factors such as temperature, soil pH, and moisture content.

When nitrogen is lost through volatilization, it not only reduces the amount of nitrogen available to plants but also contributes to atmospheric pollution. This makes the statement true, as volatilization signifies a tangible loss of nitrogen from the soil to the atmosphere, which can affect crop yields.

Focusing on the other statements, they each introduce conditions or factors that may limit or explain the occurrence of volatilization. However, the fundamental understanding of volatilization inherently includes that it involves a loss of nitrogen, making the original assertion accurate.
