The study looked at how soil nutrients are distributed on sloping land in the gully region of the Loess Plateau. They found that soil organic carbon and total nitrogen decreased the most with depth, while nitrate nitrogen, ammonium nitrogen, and total phosphorus decreased less. The amount of small soil particles increased with depth, and nutrients tended to be enriched in middle and lower positions of long, gentle slopes. Short, steep slopes saw nutrients being transported away. Soil erosion and sediment deposition were key factors in nutrient distribution, with slope gradient affecting the depth of carbon and nitrogen loss. The study suggests that managing soil nutrients on sloping land should consider the length and gradient of the slope.
