Tematy:: Bacterial biomass, carbon biogeochemistry, climate change, fungal biomass, protozoan biomass, soil carbon enrichment
Opis:: The ecology of tundra terrestrial environments has gained increasing attention due to potential major changes resulting from global warming and climate change. However, the composition of terrestrial microbial communities and their role in the biogeochemical carbon cycle are less well studied. This is the first report of the C-biomass of bacteria, fungi, and representative protozoa (heterotrophic nanoflagellates, naked amoebae, and testate amoebae) in Alaskan tundra soil samples, and the effects of glucose solution enrichment in laboratory studies simulating release of soluble organic compounds as may occur during permafrost melt and increased plant root exudates due to global warming. The data for three moss-rich surface samples, two in spring and one in summer (2011), are reported for C-supplemented (8,000 μg glucose-C) and non-supplemented treatments in laboratory culture. Seven days after supplementation, fungal C-biomass in the glucose-treated and untreated samples were similar in the range of 5 to 11 mg g–1 soil dry weight, the highest values in the summer samples. The bacterial C-biomass was the next highest in the range of 20 to 120 μg g–1 soil dry weight, followed by heterotrophic nanoflagellates (2 to 14 μg g–1 soil dry weight). The naked amoebae (0.13 to 0.94 μg C g–1 soil dry weight) and testate amoebae (2 to 20 ng C g–1 soil dry weight) contributed the least C-biomass. All of the bacterial and protozoan treatments showed increased biomass with glucose supplementation. Based on size, and C-biomass estimates, the phagotrophic protozoa appear to be organized in a classical bacterial-based trophic hierarchy (i.e. bacteria – nanoflagellates – naked amoebae – testate amoebae, in ascending order). Correlations of the C-biomass of bacteria to each of the protozoa, provided further evidence of a trophic pyramid; bacteria vs. nanoflagellates (r = –0.986), indicating top-down control by predatory flagellates, bacteria vs. naked amoebae (r = –0.361) and bacteria vs. testate amoebae (r = –0.131), each of decreasing magnitude as would be predicted for higher level consumers. Estimates of bacterial predation indicated strong predatory pressures on bacteria by the protozoa, greater with C-supplementation compared to the non-supplemented treatments.

BioBaler harvesting system
Opis:: Willow biomass can be collected in the form of entire or chipped shoots. The method depends on the harvest cycle of the plants, availability of necessary machines and the expected use of harvested raw material. Methods of harvesting influence on biomass quality during its acquisition and further in the storage period. Therefore, the aim of the research was to characterize the harvest of willow plantation with the use of a biobaler WB 55 and to assess the quality of the obtained biomass during the 9-month period of its storage. Willow was harvested with biobaler WB 55 in January 2010 on a commercial plantation. The 3.5 ha plantation was situated in the north-east of Poland, in the village of Dorotowo (53°42′9.88″ N 20°25′11.02″ E). An analysis of the biomass quality in terms of its thermophysical and chemical properties was carried out at the laboratory of the Department of Plant Breeding and Seed Production of the UWM in Olsztyn. Willow harvesting with a unit consisting of a 129 kW tractor and biobaler WB 55 was conducted efficiently. The average harvesting efficiency was about 18 bales per hour of the unit operation (8.75 Mg h-1 FM). The fresh matter density in the bales averaged 358.10 kg m-3 FM, whereas in dry matter it was 166.16 kg m-3 DM. With extended duration of storage, the quality of willow biomass as an energy raw material improved. The biomass in the bales steadily lost its moisture, from 53.06% in January to 17.48% in September. On the other hand, the lower heating value increased during that same period from 7.75 MJ kg-1 to 15.65 MJ kg-1. It has been found based on the observations made during the study period that the advantages of a biobaler WB 55 are the easy and efficient harvesting of plants on a plantation and bales can be used for energy production as needed.

Opis:: Solidago canadensis (Canadian goldenrod) is an invasive plant species occurring in Poland. Canadian goldenrod tolerates a wide range of habitat conditions, it grows in landfills and soils contaminated with heavy metals. The paper presents the selected biometric features of the plant which indicate the possibility of its use for phytoremediation purposes. The analysis was based on the results of own research and literature data. The biometric features of the plant chose for the research are: aboveground biomass (which reaches about 4.4 tons d.m/ha on a surface covered with the plant in more than 70%), the possibility of annual collection of the aboveground parts and their use for energy purposes, extensive roots and rhizomes system ensuring soil stabilization, high accumulation of some metals in the underground parts of the plant.

Opis:: There were done simulations of fuels consumption in the system of electrical energy and heat production based on modernised GTD-350 turbine engine with the use of OGLST programme. In intention the system based on GTD-350 engine could be multifuel system which utilise post-fying vegetable oil, micronised biomass, sludge, RDF and fossil fuels as backup fuels. These fuels have broad spectrum of LHV fuel value from 6 (10 6 J•kg -1 ) (e.g. for sludge) to 46 (10 6 J•kg-1) (for a fuel equivalent with similar LHV as propan) and were simulations scope. Simulation results showed non linear dependence in the form of power function between unitary fuel mass consumption of simulated engine GTD-350 needed to production of 1 kWh electrical energy and LHV fuel value (10 6 J•kg -1). In this dependence a constant 14.648 found in simulations was multiplied by LHV raised to power - 0.875. The R2 determination coefficient between data and determined function was 0.9985. Unitary fuel mass consumption varied from 2.911 (kg•10 -3•W -1•h -1) for 6 (10 6 J•kg -1) LHV to 0.502 (kg•10 -3 •W -1 •h -1) for 46 (10 6 J•kg -1) LHV. There was assumed 7,000 (h) work time per year and calculated fuels consumption for this time. Results varied from 4,311.19 (10 3 kg) for a fuel with 6 (10 6 J•kg -1) LHV to 743.46 (10 3 kg) for a fuel with 46 (10 6 J•kg -1) LHV. The system could use fuels mix and could be placed in containers and moved between biomass wastes storages placed in many different places located on rural areas or local communities.

Opis:: The study evaluated physicochemical properties of bio-waste as a potential biofuel in the form of leaves from ‘Regent’ grapevines grown on six different rootstocks and a control grown on its own roots for three years of cultivation. An elemental analysis was carried out, determining the content of carbon, hydrogen, nitrogen, and sulphur in the leaves tested. A technical analysis of the biofuel was also carried out to determine the content of moisture, volatile matter, and ash. The calorimetric method was used to determine the higher heating value for the material. Fixed carbon and oxygen carbon was calculated based on the elemental and technical analyses. The study showed that the type of rootstock and the year of cultivation influence the amount of leaves obtained from the cultivation area. Leaf entrustment per hectare ranged from 1,140,868.02 in rootstock 161-49 to 1,265,286.7 Mg∙ha-1 in rootstock SO4. Regardless of the year of the study, shrubs grafted on 125AA rootstock and the control had the highest combustion heat of 17.5 MJ∙kg-1 and 17.6 MJ∙kg-1 respectively, while 5BB rootstock had the lowest combustion heat (16.4 MJ∙kg-1). Statistical analysis showed no significant effect of test year on the elemental and technical parameters evaluated. It was observed that regardless of the evaluated parameter and the type of rootstock in most parameters, the values in 2022 were the highest, while in 2021 they were the lowest.
