资源简介:
After air drying and sieving (2 mm), the soil samples were analyzed for determine nutrient contents and CEC. The Kjeldahl method was used to determine total N (TN) and CEC. Molybdenum-antimony anti-colorimetry and flame photometry were performed to quantify available phosphorus (AP) and available potassium (AK), respectively. For the determination of of OM, the potassium dichromate oxidation-external heating method was used. Soil bulk density (BD) was measured by oven drying (24 hours, 105°C) and weighing the soil samples in cutting rings, and the BD of the first soil layer was taken as the final result. The calculation results of soil acidification rate and contribution degree are listed in the table. In order to ensure the privacy of the data, the formulas and explanations in the table are deleted
