<u>Nitrogen and potasium levels</u> are NOT primary measures of soil quality.
Explanation:
The deeper the soil horizon, the more fertile the soil. This is because this means the soil has had enough time to weather and release the elements/minerals held up in the parent rock.
Soil composition is also important for soil quality. The good ratio silt, clay, and sand can determine the quality of the soil. This same composition can determine the holding capacity of water in the soil for plants and other soil organisms.
Organic matter is important in raising soil quality. They ensure the soil retains water nutrients from leaching
