Which of the following is NOT typically used as a key indicator of soil health in rangelands?

• A. Soil Organic Matter
• B. Aggregate Stability
• C. Soil Depth
• D. Soil Texture

Answer: (D)

Soil health indicators in rangelands focus on how well the soil functions under grazing—its ability to support plants, move water, and host biological activity. Soil organic matter is a primary sign because it directly enhances nutrient cycling, water holding capacity, and soil biology, all of which reflect a healthy, resilient soil system. Aggregate stability is another crucial indicator because it shows whether soil structure stays intact through wetting, drying, and trampling, which preserves pore spaces for air and water and helps prevent erosion. In contrast, soil texture is a fundamental, relatively static property describing the mineral makeup of the soil; it doesn’t change with management on short timescales and doesn’t directly signal current soil health status. For that reason, texture isn’t typically treated as a key indicator of soil health in rangelands.
