Potential Use of Organic- and Hard-Rock Mine Wastes on Aided Phytostabilization of Large-Scale Mine Tailings under Semiarid Mediterranean Climatic Conditions: Short-Term Field Study

Table 8

Tables of two-way analysis of variance for microbial accumulated basal respiration and microbial biomass C (mean ± standard deviation, 𝑛=3) in experimental substrates (0–20 cm) from the time of establishment of the field assay (year 1 or 2006) and after 2 years (year 3 or 2008).
