If nearly 79 of the atmosphere is made of nitrogen how could there be a shortage of nitrogen in soil?
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.
If nearly 79 percent of the atmosphere in nitrogen How could there be a shortage in some soils?
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.
What are the different ways by nitrogen in the air reaches the soil?
Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use. Nitrogen can also reach the soil through precipitation, as nitrogen compounds are washed out of the atmosphere and deposited onto the soil surface. Additionally, nitrogen can enter the soil through the decomposition of organic matter, releasing nitrogen back into the soil as plant nutrients.
What is the transfer of nitrogen from air to soil to organism and back to air or soil?
Nitrogen is transferred from the atmosphere to the soil through processes like nitrogen fixation by bacteria or lightning, where plants can uptake this nitrogen from the soil. Organisms then consume these plants, incorporating the nitrogen into their own tissues. When organisms die and decompose, nitrogen is released back into the soil, where it can be recycled back into the atmosphere as nitrogen gas through denitrification by bacteria, completing the nitrogen cycle.
How does nitrogen exit the soil?
Nitrogen exits the soil through processes like leaching, where excess nitrogen moves through the soil and into water sources, and denitrification, where bacteria convert nitrogen compounds into gaseous forms that leave the soil. Plants can also take up nitrogen from the soil, reducing the amount present.

How can there be a shortage of nitrogen in some soil?
Nitrogen in soil can become limited if there is an imbalance in the nitrogen cycle, where plants remove more nitrogen than is being replenished through processes like nitrogen fixation. Factors such as over-fertilization, leaching, erosion, and poor crop rotation can also contribute to nitrogen depletion in soil.
How is there a shortage of nitrogen in some soils?
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.
How by growing pulses Increases the soil fertility?
Roots of the plant contain a bacteria called rhizobium, and they could convert the atmospheric nitrogen into compounds of nitrogen in the soil, thus improving the soil fertility.

What does not increase the amount of nitrogen in the soil?
It doesn't. Harvesting removes soil nitrogen
Does soil contain nitrogen?
Yes, soil does contain nitrogen.
How is nitrogen depleted from 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.

How nitrogen in soil is detected?
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
If nearly 78 of the atmosphere is made of nitropen how could there be a shortage of nitrogen?
While nitrogen makes up about 78% of the atmosphere, it is mainly in the form of N2 gas, which is not readily available for use by plants and animals. Nitrogen is needed in a bioavailable form, such as nitrate or ammonium, for living organisms to use. The shortage of nitrogen refers to the availability of bioavailable forms of nitrogen, which can be limited in certain ecosystems due to factors like leaching, denitrification, or high demand by plants.
