The operation of biogas plants solves environmental aspects (energy management, reduction of negative impacts on the environment, use of renewable energy sources) and their influence in connection with the production of acidogenic (solid) as well as methanogenic (liquid) digestate. This requires establishing mandatory solution procedures in terms of the current legislation (air protection, use of fertilizers). The research for the thesis was carried out in the Agricultural and Commercial Cooperative in Kámen (in the region of Havlíčkův Brod), which lies 527 metres above the sea level. A biogas station has been operated by the cooperative since 2011. In addition to biogas, the cooperative also utilizes the fermentation remnants separated methanogenic digestate as a fertilizer and acidogenic digestate as a raw material for the production of compost. The thesis examined the use of methanogenic digestate when growing silage maize. During the one-year research, two maize hybrids and their response to fertilization by methanogenic digestate were assessed. Both hybrids achieved a higher yield of biomass and a higher yield of the dry matter.
