“…(); however, our N values were in agreement with those reported by Slepetiene et al. () and were similar to those in other crops that could be used for bioenergy production (Povilaitis et al., ). There was a high fluctuation of N concentration in the cocksfoot biomass which may have been influenced by the high variation of weather conditions as well as by the year of sward use.…”

Anaerobic digestion of biomass produces biogas for combustion and also provides a residual digestate. Although sometimes regarded as a waste product, the nutrient‐rich chemical composition of digestate makes it a potential organic fertilizer for agriculture. The goal of this study was to evaluate the effectiveness of digestate as a fertilizer on the biomass yield and chemical composition of cocksfoot (Dactylis glomerata L.). In a 5‐year small‐plot field experiment digestate fertilization treatments supplying 90, 180, 270, 360 and 450 kg N ha−1 were compared with untreated plots and plots fertilized with 180 kg N ha−1 of mineral N fertilizer. Swards fertilized with digestate produced higher biomass yield compared with the control. The same rate of nitrogen fertilizer (180 kg N ha−1) supplied as digestate and from mineral fertilizers gave similar results on biomass yield. Herbage in swards fertilized with digestate contained less nitrogen, but the C:N ratio was much more suitable for biogas production. Digestate fertilization resulted in higher concentrations of cellulose and hemicellulose in biomass and lower contents of the inhibitors of anaerobic digestion—sulphur, calcium, magnesium and phosphorus—compared with those of swards receiving mineral fertilizers.

“…Heating value of A. dubia with fertilization (Table 3) or without differed negligibly and this value is in good agreement reported for other crops (Jasinskas et al, 2008;Siaudinis et al, 2015;Povilaitis et al, 2016).…”

“…The highest yield of A. dubia biomass was produced in the swards with mineral nitrogen fertilization at a rate of 170 kg ha -1 N; however, it was insignificantly higher compared to the yield reached not only at a rate of 90 kg ha -1 N but without fertilization also. Our results indicate a high potential yield of A. dubia with and without nitrogen fertilization when compared, for example, with tall fescue or reed canary grass at the same location (Pocienė, Kadžiulienė, 2016) or investigated related species A. vulgaris (Siaudinis et al, 2015), or intensively cropped maize (Povilaitis et al, 2016). More studies were carried out on reed canary grass in Northern European countries, the estimated dry matter yields ranged between 5-10 t ha -1 depending on management (Kukk et al, 2011;Tilvikiene et al, 2016).…”

In recent years, there has been increasing interest in the use of agricultural biomass for energy purpose in many northern countries. This has created demand for novel, high biomass yielding, specific quality crops for sustainable use. The aim of the current study was to examine Artemisia dubia Wall. for biomass yield and biomass characteristics important for combustion in the temperate climate conditions. The crops were grown on an EndocalcariEpihypogleyic Cambisol (CMg-p-w-can) without fertilization and with mineral nitrogen fertilization at 90 and 170 kg ha -1 N rates. Nitrogen fertilization slightly increased plant height and accumulation of biomass. Moisture content in the biomass of swards applied with a higher rate of mineral N decreased more slowly compared with the lower rate. Biomass annual yield in the second and third years ranged from 15.8 to 17.1 t ha -1 ; however, significant effect of nitrogen fertilization was not observed. Nitrogen fertilization had a significant influence on N content and lignin in the biomass. The variation of values of the elements relevant for combustion (carbon and sulphur) in the biomass was negligibly influenced by nitrogen fertilization. The relatively low ash content and heating value, amounting to 8.5 MJ kg -1 achieved even without nitrogen fertilization, makes A. dubia a promising energy crop in the northern part of the temperate climate zone. More studies and analyses on A. dubia are needed to ascertain the fertilization effect on biomass yield, biomass quality and biomass properties for combustion in senescent plants.

“…In the course of soil renaturalisation processes, not only the minimal impact on the environment is very important, but lower costs of obtaining biomass of higher energy value are also essential (Renewable energy..., 2012). In Lithuania, research on the evaluation of plant biomass as energy resource is concentrated on grassland (Tilvikienė et al, 2012;Kadžiulienė et al, 2013;Skuodienė et al, 2013), less frequently on forest (Armolaitis et al, 2013) plant experiments; the use of crop rotation biomass for energy is not very popular (Šarauskis et al, 2014;Povilaitis et al, 2016).…”

The article discusses the changes in energy accumulation in the biomass during a 21-year arable land renaturalisation process. The relevance of renaturalisation studies in South-Eastern Lithuania is determined by the low-productivity of the soil covers in this area and low energy production obtained from traditional agricultural crops grown on lowproductivity agricultural soils. The aim of this study is to evaluate various methods of sandy loam Haplic Luvisol renaturalisation by comparing the total energy accumulated on pine afforested land use, unmanaged and managed grasslands against the productivity of the traditional agricultural systems. The accumulation of the total energy under various land uses was governed by the plants and their cultivation period. Downward trend of productivity during the period of 1995-2015: forest plants (195%) → fertilized managed grassland (162%) → fertilized cropland (100%) → unfertilized managed grassland (95%) → unfertilized cropland (61%) → unmanaged grassland (50%). When comparing the plant biomass production during the entire study period, it was established that mineral NPK fertilization significantly (by 1.63 times) increased the energy productivity of the cropland. It is expedient to preserve and expand the managed grasslands typical of the traditional Lithuanian landscape and crucial for the conservation of biodiversity. Furthermore, the productivity of unfertilized managed grassland is adequate to the productivity of the fertilized cropland, or exceeds it by 67% if NPK fertilizers are applied. Mineral NPK fertilization significantly (by 1.71 times) increased the accumulated total energy of the managed grassland. The accumulation of energy changes significantly in the fallowing fields. Natural vegetation plants of non-cultivated sandy loam are not productive; they produce only half the amount of the total energy compared with the cropland plants or fertilized managed grasslands.
