Changes in soil enzyme activity and bacterial abundance in lettuce-cultivated soil. a FDAase; b urease; c acid phosphatase activity; and d relative abundance of bacteria at major phyla levels under different treatments. Error bars denote ± standard error (n = 3). For different parameters, letters “a,” “b,” “c,” “d,” and “e” represent significant differences among soil treatments. According to Tukey’s test, the same letters on each bar imply that soil enzyme activity is not different at a significance level of p < 0.05
