Correlation Analysis of Soil Enzyme Activity, Soil pH, and Soil Nutrients The correlation analysis of soil enzyme activity, soil pH, and major nutrients showed the following: urease exhibited a significant positive correlation with SOC and a highly significant positive correlation with TN in the soil; catalase exhibited a highly significant positive correlation with the pH value of the soil; alkaline phosphatase exhibited a highly significant positive correlation with total nitrogen in the soil; sucrase exhibited a highly significant positive correlation with total nitrogen in the soil; sucrase exhibited a highly significant positive correlation with the pH value of the soil; and alkaline phosphatase exhibited a highly significant positive correlation with TN.
