Question

How does the use of fertilizer affect the nitrogen cycle?

Answer 1

Fertilizer puts nitrogen into the soil, so using fertilizer puts more nitrogen into the carbon cycle. When you use fertilizer, its because a certain plant you are planting uses all the nitrogen in the soil, so it won't grow next time. Too much fertilizer, though, would burn up your plant. When farmers harvest crops, a lot of the plant material is also removed. Little is left to decay and return nitrogen to the soil. If the soil stays this way, it will start producing fewer crops. Fertilizer contains the nitrogen compounds that are essential for plant growth. It can be used to replace the nitrogen in the soil to ensure the growth of healthy crops.
