Opis:
Application of sewage sludge for environmental management of fly ashes landfill site affects chemical composition of plants. The aim of the present investigations was learning the effect of growing doses of municipal sewage sludge on the yield and uptake of Fe, Mn, Al, Si and Co by grass mixture used for environmental management of fly ashes landfill. The experimental design comprised of 5 objects differing by a dose of municipal sewage sludge supplied per 1 hectare: I. control, II. 25 t d.m., III. 50 t d.m., IV. 75 t d.m. and V. 100 t d.m. Application of sewage sludge resulted in the increase in yield. The content of analyzed elements in the grass mixture depended significantly on sewage sludge dose. Increasing doses of sewage sludge caused marked increase in Mn and Co contents, while they decreased Fe, Al and Si contents in the grass mixture. It was found that growing doses of sewage sludge caused an improvement of Fe to Mn ratio value in the grass mixture. Assessing the element content in the grass mixture in the view of forage value, it was found that Fe and Mn content did not meet the optimal value. Si content in plants was below the optimal value.

Opis:
The paper aimed at comparing the yield and concentrations of zinc, copper and nickel in maize cultivated in soil fertilized with two different sewage sludge with yielding of maize fertilized with manure and solely with mineral fertilizers. The experiment was conducted in plastic pots, of which each contained 8.5 kg of air-dried soil with granulometric composition of light sandy loam and neutral pH. Sewage sludge used for the experiment originated from two municipal sewage sludge treatment plants in Krzeszowice (sludge I) and Niepołomice (sludge II), while manure from a private farm in Czernichów district. The test plant was maize (Zea mays) cultivated for 74 days and then harvested for green forage. On the basis of conducted research it was found that various fertilizer combinations applied in the experiment had a significant influence on the test plant yielding. All compared fertilizer variants allowed maize to produce statistically significantly higher yield in comparison with the yield harvested from the unfertilized soils. Fertilization with sewage sludge I supplemented with mineral treatment and application of solely mineral salts proved the most beneficial for the maize yield. Applied fertilizer combinations affected the content of microelements. The highest concentrations of nickel in maize green mass were assessed in plant samples from the unfertilized object, whereas zinc and copper from mineral fertilization variant. Except of zinc, introducing additional metal doses did not influence their increased content in plant organs. Soil enrichment with zinc contained in sewage sludge I and II (respectively 77.4 mg and 49.9 mg ∙ pot-1) contributed to its elevated concentration in maize roots but at the same time this metal content statistically significantly decreased in maize shoots in comparison with the amounts determined in plants fertilized with mineral materials.

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:
Organic recycling of waste, taking into account sanitary safety, should be a fundamental method for recovering the nutrients present in the waste for plants and organic matter. It also refers to byproducts of animal origin, which are not intended for con-sumption by humans. In the present research , composting of hydrated poultry slaugh-terhouse waste with maize straw was carried out. A combination with fodder yeast and post-cellulose lime was also introduced, which modified chemical and physico chemical properties of the mixtures. The experiment was carried out by recording the biomass temperature for 110 days in 1.2×1.0×0.8 m reactors with perforated bottoms enabling active aeration. The following parameters were taken into consideration in the composted material: carbon, nitrogen, sulfur, respiratory activity, microorganisms, fractions of compost obtained after washing on sieves. Small amounts of fodder yeast favoured the development of microorganisms and caused a sanitary risk in the final product. At the initial stage, the temperature of raw compost in that object was several degrees lower than in the case of the composted mass without yeast addition. The addition of post-cellulose lime at ratios 6.5:1:6.5 (maize straw: poultry slaughterhouse waste: post-cellulose lime) caused a change in the time of microbiological activity, and led to its inhibition in the final process. In comparison to objects with poultry waste, the highest degree of hygienization was found in the compost with post-cellulose lime (with pH close to neutral). By adjusting the ratios of substrates we can influence the microbiological activity, but the amounts of individual substrates should be determined taking into account the quality of the obtained compost.
