Yes, soil does contain nitrogen.
when animals eat plants,they get nitrogen compounds that their bodies need.plants do not make these nitrogen compounds. so from where do plants get their nitrogen compounds/ from the air
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
Nitrogen compounds known as Nitrates found in the soil
Legumes "fix" nitrogen in nodules on their roots, so they do not need additional nitrogen-containing fertilizers.
Nitrate fertilizer refers to a type of fertilizer that contains nitrogen in the form of nitrate ions. This form of nitrogen is readily available to plants for absorption, helping to promote healthy growth and higher yields. Nitrate fertilizers are commonly used in agriculture to provide plants with the essential nutrient they need for optimal development.
Producers get nitrogen through the nitrogen cycle, which involves various processes such as nitrogen fixation by bacteria in the soil, assimilation by plants, and decomposition of organic matter. Plants can also absorb nitrogen from the soil through their roots in the form of nitrates and ammonium. Nitrogen can also be added to soil through fertilizers.

Nitrogen is added to soil through biological processes such as nitrogen-fixing bacteria converting atmospheric nitrogen into a form plants can use, as well as through decomposition of organic matter like plant material or animal waste. Additionally, nitrogen can be added to soil through synthetic fertilizers containing nitrogen compounds.
Because leguminous plants are capable of fixing free nitrogen from the air with help of their root nodules. Thus soil get rich in nitrates in those places where these plants are grown.
No, but they do need the nutrients commonly found in the soil, and nitrogen fixing soil bacteria are extremely beneficial, though not technically necesary, to plants.
Curse: Denitrifying bacteria convert the nitrogenous compounds into free nitrogen, hence reducing the nitrogenous compound levels in the soil. Boon: Denitrifying bacteria prevent the plants from having too much nitrogen. Extra nitrogen could harm the ecosystem as a whole, because some wild plants like cultivated crops can thrive on nitrogen. The growth of these plants is favoured in nitrogen-saturated environments. This upsets the ecosystem. Some of this sort of damage is seen in colder countries, where natural nitrogen cycling is slowest.
Fertilizers are added to crops to provide essential nutrients like nitrogen, phosphorus, and potassium that plants need for healthy growth. These nutrients can be lacking in the soil or depleted by previous crops, so adding fertilizer helps improve soil fertility and crop yield.
Fertilizers are added to soil to increase nutrient levels. Common fertilizer types include nitrogen, phosphorus, and potassium, which are important for plant growth. Organic matter such as compost can also be added to the soil to improve nutrient levels.
It doesn't. Harvesting removes soil nitrogen
Yes, nitrogen is an important nutrient for plant growth and plays a key role in soil fertility. It is a component of chlorophyll, the molecule that allows plants to photosynthesize, and is also necessary for protein synthesis in plants. Nitrogen can be added to the soil through fertilizers or by planting nitrogen-fixing crops like legumes.
