1、Factors Affecting Nitrogen Fertilizer Volatilization

High soil pH and high temperatures cause higher rates of volatilization because 1) they increase soil concentrations of ammonia dissolved in soil water and 2) warm soil water cannot hold as much ammonia gas.

2、Nitrogen mobility, ammonia volatilization, and estimated leaching loss

The aim of this study was to evaluate the fate of N fertilizers applied to acidic red soil (Ferralic Cambisol) after 19 years of mineral (synthetic) and manure fertilizer treatments under a cropping system with wheat-maize rotations.

3、The Science Behind Volatilization in Soil Management

In the context of soil management, volatilization primarily involves the loss of nitrogen compounds, especially ammonia (NH₃), from fertilizers applied to soil.

4、Nitrogen volatilisation losses ‐ how much N is lost when

Fertiliser nitrogen can be lost from the soil surface as ammonia gas via the process of volatilisation. Just how much is lost depends on a range of factors, including; soil moisture, temperature, pH, naturally‐occurring lime in the soil, ground cover, wind, soil clay %, and fertiliser type.

5、Volatilization: Understanding Nitrogen Loss

Learn about volatilization, one of the main nitrogen loss mechanisms. Discover how it occurs and ways to reduce this form of nitrogen loss.

Keeping Fertilizer in the Ground and Out of the Air

“Any nitrogen loss from the soil system will potentially impact either yield or quality of crops,” Engel says. Hershberger changed his practices by applying fertilizer below the soil surface when planting, injecting it directly into the soil so it does not have the chance to volatilize.

The extensive use of nitrogen (N) fertilizers during the cultivation of both crops leads to significant losses of reactive nitrogen (Nr) into the environment.

Nitrogen loss pathways. How much N is lost when urea is not

If surface-applied urea is not incorporated into the soil, some of the nitrogen (N) may be lost via volatilisation of ammonia (NH 3) gas from the soil to the atmosphere. Runoff of dissolved urea soon after fertiliser application can also occur if intense rainfall exceeds infiltration.

Nitrogen losses from the soil included the output fluxes from NH 3 volatilization, emissions of nitric oxide (NO), nitrous oxide (N2 O), dinitrogen (N 2), crop uptake, leaching and runoff (Deng et al., 2015; Li, 2000b).

Will Nitrogen Fertilizer Volatilize if Left Unburied in the Soil? Why?

Nitrogen fertilizer is an indispensable resource in agricultural production, providing essential nitrogen nutrition for plant growth and development. a common question arises during its application: Will nitrogen fertilizer volatilize if left exposed on the soil surface without being buried? Why or why not?

First, it is crucial to understand what nitrogen fertilizer is. Nitrogen fertilizers contain nitrogen in compound forms, such as urea, ammonium nitrate, and others. Nitrogen is a vital nutrient for plants, promoting cell division, elongation, and overall vigor. Proper application of nitrogen fertilizers significantly boosts crop yields.

Now, addressing the core question: No, nitrogen fertilizer does not volatilize when left on the soil surface. The nitrogen in these fertilizers exists in stable chemical compounds (e.g., urea remains as urea, ammonium nitrate as ammonium nitrate). These compounds are resistant to microbial decomposition and conversion into gaseous forms under normal soil conditions. Thus, no significant volatilization occurs when nitrogen fertilizers are applied topically.

application rate and method strongly impact nitrogen utilization and environmental safety. Excessive or improper use of nitrogen fertilizers can lead to waste and pollution. For example, overapplication may cause nitrogen to leach into groundwater or convert into harmful gases like nitrous oxide (N₂O) under certain conditions. farmers should tailor nitrogen doses and application techniques to crop requirements and soil properties.

Timing is also critical. Nitrogen should primarily be applied during the early and mid-growth stages of crops, as plants demand more nitrogen for rapid development. Conversely, reducing or ceasing nitrogen application in the late growth stage prevents excessive nutrient uptake, which could impair crop quality or delay maturity.

nitrogen fertilizer does not volatilize when left unburied. optimizing its use requires attention to dosage, timing, and application methods. By doing so, we maximize agricultural productivity while minimizing environmental risks.
