Soil nutrient indicators under different simulated erosion and deposition scenarios following peanut harvest. Indicators include soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP), available nitrogen (AN), and available phosphorus (AP). Treatments S1 to S5 represent erosion depth of 20 cm (SE20), erosion depth of 10 cm (SE10), no erosion (SE0), surface accumulation of 10 cm (SA10), and surface accumulation of 20 cm (SA20), respectively, all under unfertilized conditions.
