“…1) July harvesting was more suitable for reed canary grass fertilized with mineral nitrogen, while tall fescue gave better results in digestate fertilization treatment when harvested in October, which agrees with other authors' data suggesting that late harvesting is preferable for grasses (Cherney, Verma, 2013;Rancane et al, 2015). While according to Seppälä et al (2009), the biomass yield of tall fescue could vary depending on harvesting time and it was highest when harvested July harvesting, which is contrary to our experimental data.…”

“…Seasonal variation of herbage biomass also occurred and, commonly, the content of hemicellulose in the herbage biomass was higher in August than in May (Elgersma, Søegaard, 2016). As a rule, with grass aging the quality of herbage tended to decline (Seppälä et al, 2009;Elgersma, Søegaard, 2016). However, the requirements for biomass properties for feed or anaerobic digestion are completely different from those intended for combustion.…”

“…Tall fescue (Festuca arundinacea Schreb.) has also been reported as one of the grasses suitable for bioenergy in northern climate and its yields could range from 1 to more than 10 t ha -1 (Seppälä et al, 2009;Lemežienė et al, 2011;Tilvikiene et al, 2016). In different soil and climatic conditions the biomass yield of the same grass species is different and it is always associated with the growing technology, stages of plant development and their interactions (Jasinskas et al, 2008;Butkute et al, 2014;Kołodziej et al, 2016).…”

Grass biomass is a potential feedstock for solid biofuel production. This paper presents the results of experiments conducted on Endocalcari-Epihypogleyic Cambisol (CMg-p-w-can) to evaluate the biomass yield, quality and bioenergy potential of tall fescue (Festuca arundinacea Schreb.) and reed canary grass (Phalaris arundinacea L.). Two kinds of fertilizers mineral nitrogen (90 kg ha -1 ) and biogas waste (digestate) with the same amount of nitrogen and one-cut regime either in July or in October were chosen to estimate the biomass productivity and energy potential. The results of a two-year experiment suggest that the biomass yield and energy potential depended on the grass species and cultivation technology. Higher biomass and energy yields were produced by reed canary grass when harvested in July, while by tall fescue when harvested in October. Both grass species were most productive when fertilized with mineral nitrogen. Of the two grass species and harvesting dates tested, the highest biomass and energy yields were produced by reed canary grass swards harvested in July. It was proved that the highest content of lignin in the biomass led to the highest energy yield of swards.

“…It is believed that the successfully operating biogas plant must operate not less than 8500 hours (Horbelt et al, 2011). The different field due to its high content of lignin and cellulose (Hartmann, 2006;Seppälä et al, 2009). The CH 4 concentrations in the extracted biogas ranged from 59% to 62%.…”

The research was aimed to investigate the energy biomass productivity and biogas production from silage of different perennial grasses with evaluation of greenhouse gas emissions through the entire process from biomass cultivation to processing. The experiments with perennial grasses -cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Scherb.) and reed canary grass (Phalaris arundinacea L.) were carried out at Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry in 2008-2010. The swards were grown in an Endocalcari-Endohypogleyic Cambisol (CMg-n-w-can), which contained: organic carbon -1.61-1.75%, available P -145-224 mg kg -1 and K -128-158 mg kg -1 , soil pH ranging between 6.7-7.0. The three perennial grass species with varying yields of biomass were used to ensure a steady operation of the selected biogas plant of 500 kW e electric power. The different quantities of biomass feedstock and varying energy input are required for such biogas plant. Therefore all data correspond to a biogas cogeneration plant of 500 kW e electric power. Required land area for the same amount of energy produced depends on species of perennial grasses, rates of fertilization and number of cuts. These results mainly depended on the biomass productivity and biogas yield from dry mass. Biomass yield from dry matter in the first year of use of tall fescue cut twice per vegetation season was higher compared to that cut three times, while cocksfoot and reed canary grass yielded better cut three times compared to cut twice. The highest yield was obtained in tall fescue swards cut twice and fertilized with N 180 . The total balance of greenhouse gas emissions showed their mitigation and ranged from 0.206 to 0.298 kg CO 2 eq kWh -1 .

“…For instance, Nakasaki, Aoki and Kubota [6] state that the progress in accelerated composting resulted in decreased costs; however, as Maroušek et al [7] points out, the accelerated composts have the low ion-exchange capacity, hence it hardly provides any advantage in terms of its fertilization value. The grass cuttings can be utilized in biogas production [8]; in this case, though, this is associated with bad odor for which reason the approach to the waste cost reduction is difficult to implement on a large scale.…”

Abstract. The public sector is an inseparable part of every economy. It performs a number of functions such as providing public services, environmental protection, defense, security, education, health, justice and many others. Each institution's duty is to care for its own property. Public spaces, parks and other public greenery are mostly owned by municipalities. Taking care of public greenery is a part of public spending because the source of money is municipal budgets.
