Nitrogen is an essential element for plant growth as it forms an important part of the proteins necessary for biological processes such as photosynthesis and respiration in plants. Nitrogen is an important component of amino acids which are the building blocks of proteins. So if plants don't get enough protein, they will die. Nitrogen is also an important part of nucleic acids that helps form DNA which also makes it important for plant survival. Therefore, nitrogen plays a significant role in plant growth. Lack of nitrogen can also be harmful to a plant. This is because nitrogen is a component of the vitamins, amino acids and energy systems within the plant, which form its proteins. Therefore, nitrogen is directly responsible for the increase in protein content in plants. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

Nitrate is also very mobile in soil and moves with soil water to root surfaces for plant uptake. Therefore, it is very important to use the right amount of nitrogen in plants otherwise it can become toxic. Although nitrogen can help plant growth, too much nitrogen fertilizer can be harmful to the plant. When a nitrogen fertilizer is applied to a plant, the plant either directly absorbs the fertilizer or converts it into various other forms through the process of oxidation. However, if you use excess fertilizer, the nitrate will not be absorbed by the plant roots. If nitrogen is not absorbed by the plant's roots, it will be carried away by runoff or drained into the soil with excess water instead of being absorbed by the plant. Another negative effect of too much nitrogen fertilizer on a plant's plant would be that it can dehydrate the plant. When too much fertilizer is used, the mineral salt of the soil increases. This is because the mineral salt in the soil increases. As the mineral salt increases, water flows out of the plant and begins to mix with the soil. This is due to osmosis where water moves from a low to a high concentration. Then, due to the excess fertilizer used, the mineral salt in the soil increases, causing water to drain from the plant. Then the edges of the leaves will appear scorched, yellow and brown due to dehydration.
