Landforms in the Loess Plateau affect soil properties. This study looked at soil samples from different landforms in a small watershed. Results showed that nitrate, available phosphorus, alk-phosphatase, and invertase varied greatly, while soil pH and catalase varied less. Soils on plateaus and gully bottoms had lower pH and catalase but higher cation exchange capacity. Organic matter, nitrogen, and phosphorus decreased with soil depth. Soil properties varied in this order: plateau, terrace, sloping land, gully bottom. Soil pH differences were due to soil processes and nitrate accumulation. Cation exchange capacity differences were from soil formation, pH, and organic matter. Soil nutrient variance was linked to land use, while enzymatic activity changes were due to organic matter changes from landforms.
