planting fewer beans.

Answer 1

Usable forms of nitrogen in the soil can intentionally be increased by **allowing organic matter to decompose**. This process returns nitrogen and other nutrients back to the soil in a form that plants can utilize.

Planting more trees and lightning also contribute to the nitrogen cycle, but they are not direct methods of intentionally increasing usable nitrogen in the same way that organic matter decomposition is. Planting fewer beans would not increase nitrogen levels, as legumes like beans are known for their ability to fix nitrogen in the soil.

So, the correct response is **allowing organic matter to decompose**.
