Figure 1

Variation in microbial respiration during vermicomposting of the white grape marc Vitis vinifera v. Albariño. Individual values (n = 3) are plotted for each time point, and the curve was plotted using the “loess” smoothing method in ggplot252. The inset shows changes in earthworm density during the process. Earthworm density values are presented as means ± standard error (n = 5).
