The reason is not hard to find: According to the Intergovernmental Panel on Climate Change
According to the International Patent Cooperation Council (IPCC), between 16% and 27% of human-caused climate change emissions are related to agriculture.
However, most of these emissions are not the familiar carbon dioxide that is the culprit for global warming.
It’s another gas entirely: nitrous oxide (N2O).
N2O is what we know as "laughing gas," said NYU nutrient pollution researcher and International Nitrogen Initiative
(International Nitrogen Initiative, a group focused on nitrogen pollution research and policy making
David Kanter, vice president of the International Monetary Fund, believes that it is not getting the attention it deserves. He said:
“This greenhouse gas is often forgotten.” However, on a molecular basis, N2O plays a significant role in warming the atmosphere.
It is approximately 300 times more potent than carbon dioxide.
Like carbon dioxide, it has a long lifespan, remaining in the air for an average of 114 years before breaking down.
It also depletes the ozone layer. In short, the impact of nitrous oxide on the climate cannot be underestimated. IPCC scientists estimate that
N2O accounts for about 6% of greenhouse gas emissions, and about three-quarters of these N2O emissions come from agriculture.
Despite its important contribution to climate change, policymakers have yet to directly address N2O emissions.
N2O is still accumulating. A 2020 review of N2O sources and sinks found that over the past 40 years, N2O
Emissions increased by 30%, nearly exceeding the IPCC's highest possible emissions scenario. The culprit is agricultural land.
soils – especially because of the massive global use of synthetic nitrogen fertilizers.
Today, scientists are trying various methods of treating the soil or adjusting farming practices to reduce N2O production.

“Anything that can improve fertilizer efficiency is going to be very important,” said Michael Castellano, an expert on fertilizer use.
It will be of great help.”
An imbalanced nitrogen cycle
The Earth’s nitrogen cycle has been thrown out of balance by human activity. Before the rise of modern agriculture, farms
Most of the nitrogen available to plants comes from compost, manure, and nitrogen-fixing microorganisms, which absorb nitrogen gas (N2) and convert it into
It is converted into ammonium, a soluble nutrient that can be absorbed by plant roots.
This changed with the advent of the Haber-Bosch Process.
This makes it possible to produce ammonia fertilizer in large quantities on an industrial scale.
The widespread use of synthetic fertilizers has increased crop yields and fed the world's population. But excess nitrates and ammonium have also
Ammonia fertilizer production accounts for about 1% of global energy use and carbon dioxide emissions.
1.4% (the process requires heating the nitrogen and subjecting it to pressures of up to 400 atmospheres, so it is very energy-intensive).
More importantly, fertilizers can lead to increased N2O emissions because farmers often apply fertilizers in large quantities several times a year.
Nitrogen fertilizer is applied but cannot be fully absorbed by crops.
If these fertilizers cannot be fully absorbed by plant roots, some of them will run off into fields and pollute waterways.
The rest is taken up by a range of soil microorganisms, which convert the ammonia into nitrite and then nitric acid.
Salt is then converted into nitrogen. During this process, several steps can produce N2O as a byproduct.
Excessive fertilizers can cause pollution, including the formation of N2O. Fertilizers can be composed of ammonium or nitrate groups.
When roots do not absorb all the nutrients, the remaining fertilizer undergoes a series of microbial-mediated transformations.
Most of the nitrogen is in the form of nitrogen gas (N2), and a small amount is in the form of N2O (a potent greenhouse gas).
Return to the atmosphere.
To reduce N2O emissions, one can carefully allocate fertilizers according to crop needs, or find ways to maintain yields and save fertilizer.
To this end, scientists are trying various methods. One current research strategy is to use precision
Agricultural technology that uses remote sensing to determine when and where to add nitrogen to fields, and how much to add.
Another approach is to use nitrification inhibitors - substances that inhibit the reaction by which microorganisms convert ammonia nitrogen into nitrate nitrogen.
Chemicals that block the production of N2O and keep nitrogen in the soil for plants to grow for a longer period of time
use.
According to the International Institute for Applied Systems Analysis (IIASA),
In 2018, researchers at the Institute of Systems Analysis estimated that by 2030, if these two technologies were widely adopted,
This approach would reduce N2O emissions by about 26% compared to current practices. But researchers say that to help
These are not enough to achieve the greenhouse gas targets set out in the Paris Climate Agreement.
Exploring other strategies.
One possible approach is to harness the potential of certain microorganisms to supply nitrogen directly to plants, as nitrogen-fixing bacteria do with soybeans.

Caroline Orr, a microbiologist at Teesside University in the UK, said:
Orr, a professor of biotechnology at the University of Wisconsin-Madison, says that rather than adding new microbes, it is better to encourage the growth of the desired microbes that are already in the soil.
It was found that reduced pesticide use led to more diverse microbial communities and more natural nitrogen fixation.
In addition, N2O production is influenced by carbon, oxygen and nitrogen – all of which are affected by fertilizer use, irrigation and tillage.
Zetron’s manufacturing and production operations observe an annual scheduled shutdown in line with China’s official Spring Festival holiday each year. This temporary closure is a standard arrangement to ensure proper facility maintenance, employee rest, and smooth resumption of production after the holiday period.
Our factory typically closes for a period of 1 to 2 weeks during the Spring Festival. The exact start and end dates vary each year, following the official Chinese lunar calendar and national holiday arrangements.
To minimize impact on customer projects, Zetron proactively notifies all clients of the upcoming holiday schedule well in advance. This advance notice allows customers to properly plan their orders, adjust production schedules, and arrange shipments accordingly.
Our customer service and support teams will also provide timely updates and assistance before and after the holiday to ensure order continuity, on-time delivery, and smooth project execution. We greatly appreciate your understanding and cooperation regarding this annual arrangement.
