Interpretive Summary:

Technical Abstract: Soil organic matter is a key component of soil quality that sustains many important soil functions by providing the energy, substrates, and biological diversity to support biological activity, which affects aggregation (important for habitat space, oxygen supply, and preventing soil erosion), infiltration (important for leaching, runoff, and crop water uptake), and decomposition (important for nutrient cycling). Lack of residue cover and exposure of soil to high-intensity rainfall results in poor aggregation, reduced plant water availability, erosion, and off-site impacts of sedimentation and loss of soil nutrients to receiving water bodies. This presentation describes the development of the stratification ratio concept and its implementation in evaluating soil quality on farmers’ fields.
