Phytomass as a renewableenergy source in conditionsofthe Czech Republic

Original language description

A new research carried out in 2018 – 2020 addressed the use of grasses as catch crops in order to determine the production of dry matter and energy in selected grass species and their mixtures. Mixtures of Lolium perenne 'Kentaur', Festuca rubra 'Zulu' and Festuca arundinacea 'Kora' were included in the research. Grasses were established during the business year in three terms as summer, stubble and winter catch crops. In 2019, the dry matter yield of selected grass mixtures ranged between 5.5 t.ha-1 and 12.7 t.ha-1 . The stated yields correspond to a tonne of coal equivalent of 3.33 t.ha-1 to 7.6 t.ha-1 . Dry matter yield in 2020 for selected grass mixtures ranges between 5 t.ha-1 and 12.3 t.ha-1 . The stated yields correspond to a tonne of coal equivalent of 3.03 t.ha-1 to 7.36 t.ha-1 . At the same time, dry matter production was monitored in 2018 – 2020 on an uncultivated land, former meadows and an arable land at one site. Dry matter production ranged between 1.08 and 1.53 t.ha-1 . This also corresponds to the energy production of 0.62-0.92 t.ha-1 equivalent tonne of coal equivalent. The total production of dry matter and energy is 6–8 times lower compared to the monitored grass mixtures usable as catch crops. The occurrence of weeds dangerous in sowing procedures of agricultural production such as Elymus repens, Cirsium sp., Rumex sp. has been reported on an uncultivated land. From an agricultural and landscape perspective such negative phenomena in the form of spontaneous fallow land must be eliminated. Intercrops increase the stability of the landscape agroecosystem, especially in relation to soil, and based on this research grasses grown as intercrops can be recommended and used in agricultural sowing practices. The resulting biomass of catch crops can be used for bioenergy purposes.
