Abstract: In order to ascertain the interaction within soil phenolic acids and the main properties of soil, soils of different plantation years (1, 6, 8, 14, 16 a) in the same area were selected as study objects. The types and contents of phenolic acids, soil physicochemical properties and the characteristics of soil enzymes activities were analyzed. On the basis of correlation analysis, the gradual regression model was used to explore relationships within phenolic acids and soil properties in continuous cropping tobacco soil. It was shown that continuous cropping resulted in the accumulation of phenolic acids, decrease of soil pH and nutrient imbalance. Correlation and stepwise regression analysis showed that soil pH was inhibited by phloroglucinol. Catalase activity was increased by cinnamic acid. Urease activity was inhibited by carbamic acid. The contents of phloroglucinol, caramelic acid and total phenolic compounds were inhibited by urease activity. The contents of p-hydroxybenzoic acid and cinnamic acid were either inhibited or increased by catalase activity. Ferulic acid content was inhibited by catalase and urease, yet was increased by invertase. The contents of phloroglucinol, p-hydroxybenzoic acid and total phenolic acids were inhibited by soil pH.

Key words: continuous cropping, stepwise regression analysis, soil physiochemical properties
