What does NVOL mean in ACADEMIC & SCIENCE
NVOL stands for N VOLatilisation. It refers to the process by which nitrogen is released from the soil into the atmosphere. Nitrogen is an essential nutrient for plants, but it can also be a greenhouse gas when it is released into the atmosphere in certain forms.
NVOL meaning in Academic & Science in Academic & Science
NVOL mostly used in an acronym Academic & Science in Category Academic & Science that means N VOLatilisation
Shorthand: NVOL,
Full Form: N VOLatilisation
For more information of "N VOLatilisation", see the section below.
Factors Affecting NVOL
- Soil temperature
- Soil moisture
- Soil pH
- Plant cover
Consequences of NVOL
- Climate change: NVOL can contribute to climate change by releasing nitrogen oxides into the atmosphere. Nitrogen oxides are greenhouse gases that trap heat in the atmosphere, leading to global warming.
- Water pollution: NVOL can also contribute to water pollution by leaching nitrates into groundwater and surface water. Nitrates can cause eutrophication, which is a process that leads to algal blooms and fish kills.
Essential Questions and Answers on N VOLatilisation in "SCIENCE»SCIENCE"
What is NVOL?
NVOL stands for N VOLatilisation, representing the transformation of nitrogen (N) from soil into gases that escape into the atmosphere. NVOL can occur through several processes, including denitrification, nitrification, and volatilisation.
What are the consequences of NVOL?
NVOL can have significant environmental and economic impacts. Nitrogen loss from soil reduces soil fertility, leading to decreased crop yields and increased reliance on synthetic fertilisers. Additionally, NVOL contributes to greenhouse gas emissions, such as nitrous oxide (N2O), a potent greenhouse gas.
How can NVOL be reduced?
Several management practices can be implemented to reduce NVOL, including:
- Optimised nitrogen fertilisation: Applying nitrogen fertiliser at the right time, in the right amount, and in the right form can help minimise N losses.
- Improved irrigation practices: Proper water management can reduce waterlogging and create conditions less favourable for denitrification.
- Cover crops: Planting cover crops after harvest can help reduce N leaching and promote nitrogen retention in the soil.
- Nitrification inhibitors: These chemicals can be added to fertilisers to slow down the conversion of ammonium to nitrate, reducing the potential for NVOL.
How is NVOL measured?
NVOL can be measured using various techniques, such as:
- Micrometeorological methods: Measuring the concentration of N gases in the air above the soil surface.
- Soil sampling: Analysing soil samples to determine changes in N content over time.
- Flux chambers: Placing chambers over the soil surface to collect and measure N gas emissions.
Final Words: NVOL is a complex process that is influenced by a variety of factors. It can have both positive and negative consequences for the environment. By understanding the factors that affect NVOL, we can develop strategies to reduce its negative impacts and promote its positive ones.
