From: Agricultural management and cultivation period alter soil enzymatic activity and bacterial diversity in litchi (Litchi chinensis Sonn.) orchards

Fig. 2

Temporal variations in the soil enzymatic activities of litchi orchards that were maintained under conventional (CA) and sustainable (SA) agricultural practices. 1, 2 and 3 indicate successive trimester samplings carried out on October 2016, January 2017 and April 2017, respectively. Acid phosphatase, arylsulfatase, and β-glucosidase activities were analyzed by the p-nitrophenol method. The N2-fixing activity was detected by the acetylene reduction method using gas chromatography. Results are shown as mean ± standard deviation. The different letters labeled at columns are significantly different according to Duncan’s test (P < 0.05) by IBM SPSS Statistics v20
