In the nitrogen cycle, how does nitrogen get in the soil?

Answer 1

In the atmosphere, nitrogen is present in its elemental form. Plants cannot utilize elemental Nitrogen.

Thus, atmospheric nitrogen is fixed into the soil by nitrogen-fixing bacteria such as Rhizobium, which are also present in the root nodules of Leguminacea plants. These bacteria break down atmospheric nitrogen into nitrates or nitries and fix it into the soil, making it fertile. Plants will use these nitrates or nitrates for growth.

Answer 2

Nitrogen enters the soil through a process called nitrogen fixation, which can occur through various mechanisms. One primary method is through the action of nitrogen-fixing bacteria, which convert atmospheric nitrogen (N2) into ammonium (NH4+), a form that plants can absorb from the soil. Additionally, nitrogen can enter the soil through precipitation, where nitrogen-containing compounds dissolve in rainwater and are deposited onto the soil surface. Industrial activities, such as the use of nitrogen-based fertilizers, can also contribute to nitrogen deposition in the soil.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
