Figures & data

Table 1. Means and standard errors of soil chemical properties for the different proportions of the combined application of compost (C) and biochar (B)

Table 2. Changes of soil chemical properties during the experiment period (after the experiment) for the different proportions of the combined application of compost (C) and biochar (B)

Figure 1. Means of plant height (A) and number of tillers per plant (B) of Desho grass after 60, 90 and 120 days of growing for the different proportions of the combined application of compost (C) and biochar (B). Error bars indicate standard errors of the means. Different letters above the histograms of each growing period indicate significant differences among means, using Tukey’s test, at p < 0.05.

Figure 2. Means of number of leaves per plant (A) and leaf length (B) of Desho grass after 60, 90 and 120 days of growing for the different proportions of the combined application of compost (C) and biochar (B). Error bars indicate standard errors of the means. Different letters above the histograms of each growing period indicate significant differences among means, using Tukey’s test, at p < 0.05.
