Nothing. Nitrogen is an element, the simplest form of matter.
However, you may be thinking of what causes soil ammonium to be nitrified into the nitrate form usable by plants. This is most commonly done by nitrifying bacteria such as Nitrosomonas and Nitrobacter. See the related link below for more information on this process.
An example of adding nitrogen to soil is by incorporating organic matter such as compost or manure. These materials contain nitrogen-rich compounds that can be broken down by soil organisms to release nitrogen for plant uptake. Another method is using nitrogen-based fertilizers, which directly supply nitrogen to the soil for plants to use.
For lime trees, ammonium nitrate or urea can be used as a nitrogen source. Ammonium nitrate provides nitrogen in both the ammonium and nitrate forms, while urea releases nitrogen as it breaks down in the soil. Both forms can be beneficial for promoting healthy growth in lime trees.
An example of the nitrogen cycle is when nitrogen gas in the atmosphere is converted by bacteria into a form that plants can absorb from the soil. Plants then use this nitrogen to grow. When plants and animals die, decomposers break down their organic matter, releasing nitrogen back into the soil for plants to use again.
Nitrogen can be broken down through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into compounds like ammonia that plants can use. Another way nitrogen can be broken down is through denitrification, where other bacteria convert nitrates back into atmospheric nitrogen gas.
Nitrogen can be depleted from soil through plant uptake, leaching, and runoff. Plant roots absorb nitrogen from the soil to support growth, which can lead to a decrease in soil nitrogen levels over time. Additionally, excess water can cause nitrogen to leach out of the soil and into groundwater, or runoff can transport nitrogen into bodies of water, further depleting soil nitrogen.
Decomposers such as bacteria and fungi break down dead organisms' bodies into inorganic nitrogen through the process of decomposition. This results in the release of nitrogen back into the soil, where it can be taken up by plants for growth.
Decaying plants release nutrients, such as nitrogen, back into the soil. This process is known as decomposition, where dead organic matter is broken down by decomposers like bacteria and fungi, enriching the soil for new plant growth. Nitrogen is an essential element for plant growth and is a key component of proteins, chlorophyll, and DNA.

Soil
Decomposers
Nitrogen-fixing bacteria in the soil convert atmospheric nitrogen into a form that plants can use. Some plants, like legumes, have symbiotic relationships with these bacteria and can uptake the fixed nitrogen through their roots. Additionally, decomposers in the soil break down organic matter containing nitrogen compounds, returning them to the soil for plant uptake.
Lightning is important because it helps to balance the Earth's electrical charge, contributes to the nitrogen cycle by causing nitrogen to fix in the soil, and can trigger wildfires that play a role in maintaining ecosystems.

Decomposers have a very important role in the nitrogen cycle. They convert nitrogen found in other organisms into ammonia so it can be returned to the soil. Some use a process called denitrification to return nitrogen directly to the atmosphere.
it breaks down
Yes. When you compost something, it breaks down and returns nutrients to the soil.
For lime trees, ammonium nitrate or urea can be used as a nitrogen source. Ammonium nitrate provides nitrogen in both the ammonium and nitrate forms, while urea releases nitrogen as it breaks down in the soil. Both forms can be beneficial for promoting healthy growth in lime trees.
