• Fig. 1. Concentrations of cations in the aqueous extract of microcosmic soils under the influence of earthworms (mg/kg). The Y-axis is the concentration of cations, mg/l mean ± error of the mean, and the X-axis is the experimental options. En – Eisenia n. nordenskioldi, Lr – Lumbricus rubellus, the dashed line indicates significant differences in pairwise comparison of options, excluding control (p <0.05)
• Fig. 2.Concentrations of anions in the aqueous extract of microcosmic soils under the influence of earthworms (mg/kg). The Y-axis is the concentration of anions, mg/l mean ± error of the mean, and the X-axis is the experimental variants. En – Eisenia n. nordenskioldi, Lr – Lumbricusrubellus
