Table 6 Effects of disturbance type (Type), disturbance return internal (DRI), and their interaction on soil properties, for data collected at Archbold Biological Station, Venus, Florida, USA, from 2005 to 2014. Results of full factorial ANOVAs with disturbance variables as fixed factors. Also shown are mean values for soil variables across all burned or mown plots
