To investigate the effect of micro-mineral powder on the properties of acidified soil, this study conducted experiments by setting six different concentrations of micro-mineral powder (0%, 5%, 10%, 20%, 30%, 50%). The experimental results showed that when the concentration of micro-mineral powder was 30%, the contents of soil organic carbon, available potassium, and available phosphorus reached the highest values, increasing by 140.58%, 165.20%, and 87.78% respectively compared to the control group. The 20% concentration had the most significant effect on the content of soil hydrolyzed nitrogen (increased by 39.15%), but there was no significant difference between the 30% treatment group ( P > 0.05). However, when the concentration of micro-mineral powder was 50%, the soil pH was the highest, and the pH value of the acidic soil increased by 2.1 units compared to the control group. In conclusion, the 30% concentration of micro-mineral powder had a more significant improvement effect on acidic soil.
