According to recent research, nitrogen produced by gas-powered machines triggers dry soil to release carbon dioxide into the atmosphere, where it may cause climate change.
Nitrogen has a bad impact on soils

All forms of industrial production, farming, and, most significantly, transportation use fossil fuels which release nitrogen into the atmosphere, as per ScienceDaily.
As a result, since 1850, the amount of nitrogen in the Earth's atmosphere has tripled.
The goal of the study was to determine whether the extra nitrogen was affecting the soil's capacity to store carbon and prevent it from turning into a greenhouse gas.
This was not what they observed in dryland soil, the type which covers most of Southern California.
The group discovered that under specific circumstances, extra nitrogen causes dryland soil to become acidic and leach calcium.
Carbon and calcium form a bond before leaving the soil together. The journal Global Change Biology goes into detail about this discovery.
Nitrogen frequently has an impact on biological processes, which in turn have an impact on how soil stores carbon.
These include boosting plant growth and slowing the microbes that aid in the decomposition of dead things within the soil.
An object's acidity, alkalinity, or basicness is measured using the pH scale.
By releasing nutrients like calcium in exchange for acidity, soils typically resist significant changes in pH.
In some of the study's sites, nitrogen-induced soil acidification resulted in the soil producing calcium as a defense mechanism.
Some of the carbon that was readjusted by association with the calcium has been lost during this process.
Approximately 45% of Earth's land area is covered by drier soil, which has a limited capacity to retain moisture and little organic matter.
The majority of the carbon dioxide in the atmosphere is stored there.
Researchers advise reducing emissions as far as possible to aid in soil's ability to hold onto its carbon stores, but there is currently no known quick fix for such a phenomenon and also no clear way to stop it once it has started.
There are various methods for reducing excess nitrogen in the soil and bringing nitrogen levels back into balance, as per Family Food Garden.
Plants that will address the issue can be planted to counteract an excess of nitrogen in the soil.
Mulch is another option for fixing excess nitrogen.
It might be worthwhile to plant nitrogen-loving plants in your garden if you have the space to do so in order to gradually reduce the amount of nitrogen in the soil.
More nitrogen is typically needed for leafy green plants than for delicate flowers.
Mulching reduces nitrogen
Mulch is frequently used in gardens, but many people find that as the mulch decomposes, the nitrogen content of the soil decreases, as per Gardening know How.
You can take advantage of this normally annoying issue when there is too much nitrogen in the soil.
To help remove a portion of the excess nitrogen in the soil, you can cover the soil with mulch.
Cheap, dyed mulch is typically created from softwood scraps, which require more nitrogen to break down in the soil.
Sawdust can be utilized as a mulch to help lessen the amount of nitrogen in the soil for the same reason.
