    Opis:
    The aim of this study was to determine the effect of various additives (straw, grass, molasses, dried sugar beet pulp – pellets, inoculant, organic acids) on the quality and fermentation profile of Virginia fanpetals (Sida hermaphrodita L.) silage. Silage samples were assayed for the content of dry matter – DM, crude ash, crude protein – CP, water soluble carbohydrates – WSC, neutral detergent fiber – NDF, acid detergent fiber – ADF and acid detergent lignin – ADL as well as pH and the concentrations of ammonia nitrogen, lactic acid, acetic acid and butyric acid. Silage quality was evaluated according to the DLG Key. Apparent digestibility was determined in sheep, and the digestibility coefficients of DM, CP, NDF, organic matter – OM and digestible OM were calculated. The tested additives increased DM, decreased ADL content (P≤0.01), and reduced WSC utilization (P≤0.05, P≤0.01) in silages. Only sugar beet pulp decreased the content of NDF and ADF (P≤0.01). All silages had similar pH values (4.01 - 4.10). The analyzed silages were characterized by intense lactic acid fermentation, which was inhibited only by the grass additive (P≤0.01). All additives suppressed acetic acid fermentation (P≤0.05, P≤0.01). Grass and sugar beet pulp significantly decreased the concentration of butyric acid (P≤0.01). The addition of grass decreased CP digestibility (from 92.1% in the control silage to 89.3%), whereas the addition of a bacterial inoculant (P≤0.01) and a blend of organic acids (P≤0.05) increased CP digestibility to 93.8% and 92.8%, respectively. The addition of grass and sugar beet pulp increased the coefficient of NDF digestibility by 6 percentage points relative to 60.9% in the control silage. The addition of the inoculant and organic acids decreased NDF digestibility to 56.0% and 50.5%, respectively. Dried sugar beet pulp was the most effective additive, which positively affected the chemical composition, fermentation profile and apparent digestibility of Sida silage.

    Opis:
    A single-factor fi eld experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. In the experiment, the compost produced with municipal sewage sludge by the GWDA method and high-calcium brown coal ash (furnace waste) were used. The perennial energy crop was a test plant - Virginia fanpetals (Sida hermaphrodita Rusby). It results from the carried out study that Virginia fanpetals biomass contained on average the most manganese (24.7 mg?kg-1 d.m.), lead (2.50 mg?kg-1 d.m.) and zinc (50.5 mg?kg-1 d.m.) in 2008, while the most cadmium (0.33 mg?kg-1 d.m.), copper (3.78 mg?kg-1 d.m.) and nickel (2.57 mg?kg-1 d.m.) in 2010. Average cadmium, copper, manganese, nickel, lead and zinc contents in test plant biomass were higher, respectively by 14.3%, 10.0%, 7.3%, 19.3%, 29.1% and 6.9%, in the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to those where only calcium carbonate or high-calcium brown coal ash had been introduced into the soil. The differences in cadmium, copper, manganese, nickel, lead and zinc contents in Virginia fanpetals biomass between particular experimental objects were not signifi cant. The least zinc was absorbed by the test plant biomass in the object with high-calcium brown coal ash being applied in the fi rst year of study and annually. When evaluating the dynamics of heavy metals uptake, it was found to be the lowest in the fi rst year of study (ranging from 4.40% to 11.0%). It increased in the second and the third year of study, oscillating between 29.9% and 65.7%. The degree of heavy metals accumulation in Virginia fanpetals biomass differed, depending on the fertilisation applied. The bioaccumulation factor of cadmium, copper and nickel after three study years was average, while that of manganese, lead and zinc was intense.

    Opis:
    Municipal sewage sludge contains many valuable nutrients which can be used in the cultivation of energy crops. Application of large doses of sewage sludge can be a cause of environmental pollution, especially with nutrients. The multiflora rose and the Virginia fanpetals are plants with high nutritional requirements. The use of municipal sewage sludge in the cultivation of energy crops will allow recycling the nutrients from this organic waste. The aim of the study was to evaluate the use of macroelements from municipal sewage sludge by the multiflora rose var. "Jatar" (Rosa multiflora Thunb. ex Murray) and the Virginia fanpetals (Sida hermaphrodita Rusby). Four levels of sewage sludge fertilization were applied in the 6-year field experiment: 0, 10, 20, 40, 60 Mg DM sludge ∙ ha-1. Sewage sludge was applied once before planting energy crops. Due to the low potassium content in sewage sludge, a single supplementary fertilization with 100 kg K ∙ ha-1 in the form of 40% potassium salt (KCl) was applied on each plot. The study involved the evaluation of the yield, uptake and use by energy plants of N, P, K, Ca, Mg, and Na from sewage sludge. It was found that the increasing doses of sewage sludge significantly raised the multiflora rose and the Virginia fanpetals biomass yields. The yield of the Virginia fanpetals was one and a half times higher than that of the multiflora rose. The increasing doses of sewage sludge significantly raised the contents and uptake of N, P, K, Ca, Mg, and Na by these plants. The highest uptake of macronutrients by the multiflora rose and the Virginia fanpetals crops was determined for 60 Mg DM ∙ ha-1 fertilization dose. The results show that the Virginia fanpetals used N, P, K, Ca, Mg, and Na from the sewage sludge to a greater extent than the multiflora rose. The analyses indicate that due to the greater yields, bioaccumulation and uptake of macronutrients, Virginia fanpetals is more effective in the ‘purification’ of the substrate from excess nutrients that may pose a threat to the environment.

    Opis:
    Sida hermaphrodita as a crop plant could be used as raw material for the production of forage. The aim of this study was to evaluate the overall nutritional value of fresh and ensiled biomass of Sida hermaphrodita, harvested in the bud formation stage. The chemical and amino acid composition, fatty acid profile, concentrations of minerals and polyphenols of herbage and silage were determined. Additionally fermentation products were assessed in silage. Herbage contained crude protein (CP) of 182 g kg-1 dry matter (DM), neutral detergent fiber (NDF) of 375 g kg-1 DM and lignin content in NDF (L/NDF) was 8.88. Nitrogen fractions changed as a result of ensiling (P<0.010), non-protein nitrogen (NPN) from 274 g kg-1 total nitrogen (TN) in herbage to 683 g kg-1 TN in silage, and neutral detergent-insoluble nitrogen (NDIN) from 74.6 g kg-1 TN in herbage to 79.5 g kg-1 TN in silage. Silage was characterized by intensive lactic fermentation (114 g kg-1 DM) and pH of 4.30. It contained CP of 176 g kg-1 DM, NDF of 378 g kg-1 DM, and L/NDF (11.3) was higher than in the herbage. The CP of Sida hermaphrodita silage had a high content of essential amino acids (AAs) Lys, Thr, Val, Leu and Phe (3.98, 4.19, 4.55, 7.14 and 4.00 g 100 g-1 CP, respectively). Sida hermaphrodita silage was characterized by the highest K (6.262 g kg-1DM) content among macronutrients, and the highest content of Fe (40.88 mg kg-1 DM) and Mn (33.01 mg kg-1 DM) among micronutrients. Polyunsaturated fatty acids (PUFAs) predominated in the ether extract herbage and silage, and their proportion was three-fold and seven-fold higher than the proportion of monounsaturated fatty acids (MUFAs), respectively. Herbage had high quercetin content (652 µg g-1 DM), which decreased by 45% during the ensiling. Changes in the chemical composition suggest that this crop plant can be preserved by ensiling. The results of this study indicate that Sida hermaphrodita can be used for producing high-quality silage for ruminants.

    Opis:
    This study was aimed at determining the technological effectiveness of methane fermentation process of plant biomass from Virginia fanpetals (Sida hermaphrodita Rusby) in continuous reactors at a temperature of 37 oC. The experiment was divided into four experimental series differing in the feeding of reactor’s volume with a load of organic dry matter in the range of 1.0 kg o.d.m./m3 d to 4.0 kg o.d.m./m3·d. The highest technological effectiveness, including the quantity and qualitative composition of the biogas produced, was reached at substrate loading range of 1.0 kg o.d.m./m3 ·d to 2.0 kg o.d.m./m3·d. The reactors’ loading with the higher feedstocks of biomass resulted in diminished effects of the fermentation process.
    Celem badań było określenie efektywności technologicznej procesu fermentacji metanowej biomasy roślinnej ślazowca pensylwańskiego (Sida hermaphrodita Rusby) w reaktorach o pracy ciągłej w temperaturze 37 oC. Eksperyment podzielono na cztery serie badawcze różniące się wielkością obciążenia objętości reaktora ładunkiem suchej masy organicznej w zakresie od 1,0 kg s.m.o./m3· d do 4,0 kg s.m.o./m3· d. Najwyższe efekty technologiczne związane z ilością oraz składem jakościowym powstającego biogazu obserwowano w zakresie obciążeń od 1,0 kg s.m.o./m3· d do 2,0 kg s.m.o./m3· d. Wprowadzenie do reaktorów większych ilości biomasy skutkowało obniżeniem uzyskiwanych efektów procesu fermentacji.

    Opis:
    The purpose of this paper was to determine the effect of ash from a sewage sludge incinerating facility on yields and mineral composition of Virginia fanpetals, and on the content of heavy metals in soil. The study was based on a pot experiment in which ash obtained from sewage sludge incineration at the Lyna Wastewater Treatment Plant was used as a substitute of mineral fertilizers. The dominant fertilizing ingredients found in the analyzed ash were phosphorus and calcium. The content of cadmium and lead was lower than the allowable concentrations of these metals in mineral fertilizers. Ash from incinerated sewage sludge did not have any substantial effect on the soil content of the mobile forms of cadmium, copper, lead and chromium. With respect to three metals, namely nickel, zinc and manganese, the medium and high doses of ash raised significantly their concentrations in soil. The rate of ash had no influence on the content of sodium and magnesium in the plants but when the highest dose of ash had been applied, the concentration of calcium in plants rose significantly. Ash modified the content of heavy metals in the plant material only very slightly.
    Celem pracy było określenie wpływu popiołu ze spalania osadów ściekowych na plon i skład mineralny ślazowca pensylwański oraz na zawartość metali ciężkich w glebie. Podstawę badań stanowiło doświadczenie wazonowe, w którym popiół ze spalania osadów ściekowych z oczyszczalni „Łyna” w Olsztynie był stosowany jako substytut nawozów mineralnych. W popiele tym dominującymi składnikami nawozowymi były fosfor i wapń. Zawartość kadmu i ołowiu była niższa od dopuszczalnych stężeń tych metali w nawozach mineralnych. Popiół ze spalania osadów ściekowych nie miał istotnego wpływu na zawartość w glebie z mobilnych form kadmu, miedzi, ołowiu i chromu. Średnie i wysokie dawki popiołu znacznie zwiększyły w glebie zawartość cynku, niklu i manganu. Dawki popiołu nie miał wpływu na zawartość sodu i magnezu w roślinach, natomiast największa dawka popiołu istotnie zwiększyła zawartość wapnia w roślinach. Popiół tylko nieznacznie modyfikował zawartości metali ciężkich w materiale roślinnym.

    Opis:
    A single-factor field experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. In the experiment, the compost produced with municipal sewage sludge by the GWDA method was used and high-calcium brown coal ash at a dose corresponding. A test plant was Virginia fanpetals (Sida hermaphodrita Rusby). The obtained results show that Virginia fanpetals biomass contained on average the most nitrogen (3.72 gźkg-1 d.m.), calcium (6.03 gźkg-1 d.m.) and sulphur (1.24 gźkg-1 d.m.) in 2008, while the most potassium (4.39 gźkg-1 d.m.) in 2010. Significantly more phosphorus, magnesium and sulphur was contained by Virginia fanpetals biomass from the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to calcium carbonate or high-calcium brown coal ash being introduced into soil at the beginning of study. Differences in average nitrogen, potassium and calcium contents in the test plant biomass from particular fertilisation objects were not significant. The macroelements uptake by Virginia fanpetals biomass depended on the yield size and the content of chemical elements under discussion in it.
