because the soil holds onto it more by the nutrients in the soil
Nitrogen can become limited in soils due to factors such as leaching, denitrification, or inadequate replenishment through organic matter decomposition or nitrogen-fixing bacteria activity. Overuse of nitrogen fertilizers can also lead to a temporary shortage as plants absorb it faster than it can be replenished in the soil.
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.
Plants are the primary organisms that absorb nitrogen from the soil. They take up nitrogen in the form of nitrate or ammonium through their roots. Some microorganisms like bacteria also play a role in nitrogen fixation, converting atmospheric nitrogen into forms that plants can use.
Some bacteria in the soil, like Rhizobium and Azotobacter, are capable of converting nitrogen gas into a form that plants can use, such as ammonium or nitrates. This process is known as nitrogen fixation and is crucial for plant growth and soil fertility.
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.

Although the atmosphere is rich in nitrogen gas, plants cannot use this form directly. Nitrogen needs to be converted into a usable form like nitrates by soil bacteria for plants to uptake. In cases where the soil lacks these nitrogen-fixing bacteria or has been depleted due to overfarming, there can be a shortage of available nitrogen for plants.

It doesn't. Harvesting removes soil nitrogen
Yes, soil does contain nitrogen.
Nitrogen fixation by certain bacteria in soil converts atmospheric nitrogen into a form usable by plants. Plants take up nitrogen from soil through their roots, incorporating it into their tissues. When plants and animals die, decomposers break down their remains, releasing nitrogen back into the soil. Some nitrogen is also released back into the atmosphere through processes like denitrification.
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Plants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.
While nitrogen makes up a significant portion of the Earth's atmosphere, this form of nitrogen cannot be directly utilized by plants. Plants rely on nitrogen in the form of nitrates and ammonium found in the soil for growth. Soils can face nitrogen shortages if they lack sufficient nitrogen-fixing bacteria to convert atmospheric nitrogen into usable forms, or if excessive leaching, volatilization, or plant uptake depletes available nitrogen.
