Redundancy analysis of the temporal variation in the soil characteristics 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. The comparison between the soil properties (pH, EC, K, total N, and OM), and A enzymatic activities, B the most abundant bacterial phyla, and C alpha diversity of OTUs was done by RDA. The RDA plots were generated by the R software in the vegan package
