Nitrogen Article

1. The three chemicals used in the growth of plants: nitrogen, prohsphorus and potassium.

2. The three plants that can use N2 are soybeans, peas and clover. They are able to use it because they have a symbiotic bacteria growing in their roots. Thos bacteria have a rare ability to convert N2 into chemically usable form.

3. Nitrogen is either present as ammonia (NH3) or the ammonium
ion (NH4+) in soil or a fertilizer.

4. Nitrogen makes up 80% of the air.

5. Nitrogen can harm the environment in a way being released out and the nitrogen that had been released forms compounds that can cotribute to our changing climate and create conditions that would cause the loss of fish and other marine life. Also, when there is too much nitrogen leaking out,or there's too much being used, it doesn't go back in the atmosphere, and instead it causes the environmental pollution.

6. Scientists are breeding new crops that would live for many years. This way, farmers would not have to grow them again every year and, as a result, would use less fertilizer, which would reduce the use of nitrogen and would result with less environmental pollution.


The connection between this article and the water one is that both have a huge impact on the world and the environmental pollution. Water is needed for many purposes including food, and nitrogen is needed for growing plants and food. If there wasn't for the nitrogen, we would have a lot of trouble with growing crops, and if it wasn't for water, we would die of thirst.
