What does mineralization refer to in nutrient cycling?

Mineralization in nutrient cycling specifically refers to the process that transforms organic compounds, such as decomposing plant and animal matter, into inorganic forms of nutrients. This process is crucial because it makes nutrients available to plants and other organisms in a form that they can absorb and utilize. As organic matter breaks down through the action of microorganisms and soil fauna, essential nutrients like nitrogen and phosphorus are released in their inorganic forms, which are vital for plant growth.

The transformation from organic to inorganic is a key step in the cycling of nutrients within ecosystems, allowing for the continuous availability of essential elements necessary for life. This process contrasts with other aspects of nutrient cycling, such as the uptake of minerals by plants or the accumulation of minerals in the soil, which do not capture the essence of mineralization itself.
