Abstrakt
The potential possibility of using oilseed radish biomass of different sowing dates
(technological interval from spring to summer (post-harvest) sowing) and phenological
harvesting (budding-green pod) after the silage fermentation procedure for the production of
biogas and biomethane using the methodology of anaerobic digestion with the addition of
inoculum was investigated. Comprehensive methods for assessing the kinetics and dynamics of
production of both total biogas volumes and biomethane production levels were applied, with an
assessment of the levels of approximation of the curves of daily volume fixation.
Based on a systematic analysis with an assessment of the individual characteristics of the kinetics
of the process of anaerobic digestion of silage substrate for each variant of the experiment, the
high potential of this crop at different terms of its sowing and harvesting with a level of
bioproductivity at the level of 0.54–3.62 t ha-1 DM (depending on the phase and timing of sowing)
at the level of biomethane productivity in the range of SMY 201.03–319.66 LN kg-1
ODM at the
level of biomethane concentration in the range of 49.92–59.11%.
The maximum level of biomethane production was achieved when using silage mass (inoculum
subtracted) obtained by silage fermentation from fresh biomass harvested in the flowering phase
during the first sowing period with a level of biochemical methane potential (BMPGomp) of
344.13 LN kg-1
ODM, specific methane yield (SMY) of 319.66 LN kg-1
ODM at a maximum specific
methane production rate (Rm) of 33.74 LN kg-1
ODM d-1.
