Effect of digestate on soil microelement
After the application of the digestate in 5 and 10 L ha-1 dosages, the Cd, Co, Cu, Ni and Sr content of soil solutions did not change. The Zn content decreased significantly, while the amount of manganese (Mn) increased by almost 40% (Vago et al., 2009) (Table 5).

The increasing soluble P content of digestate treated soil decreased the available Zn content in the soil solution by building slightly soluble zinc-phosphate residue (Vago et al., 2009).
