    Opis:
    The immobilization effect of soil amendments on leaching and bioavailability of Pb, Zn and Cd in highly contaminated soils under industrial impact was studied by collecting the soils in the surroundings of Zn-Pb Smelter “Miasteczko Śląskie” in southern Poland as an example. Various amounts of four additives (phosphate fertilizer, limestone powder, bentonite rock and bog iron ore) were tested in laboratory experiments to compare the effectiveness of three dominant mechanisms of immobilization: precipitation of phosphates, pH increase, and sorption. The contents of metals before immobilization were determined by extraction in CaCl2, EDTA and aqua regia. Cadmium and zinc are mainly represented by soluble, bioavailable forms extractable in CaCl2, while lead by potentially bioavailable speciations extractable by EDTA. Most effective in the immobilization of these metals were the amendments increasing soil pH: limestone powder and phosphate fertilizer. Bog iron ore and bentonite were less effective because the soil pH was too low for efficient cation adsorption.

    Opis:
    In a 120-day incubation study, farmyard manure (FYM), mushroom compost (MC), poultry manure (PM), vermi-compost (VC), biogas slurry (BS) and biochar from Lantana sp.; a common weed (BC) each added at 15 t ha-1 significantly increased soil electrical conductivity and organic C content, however, only VC failed to increase soil organic C content significantly but increased soil pH when compared with the control sample. Among organic amendments, FYM, MC, VC and BS increased DTPA-extractable Zn and Mn in soil significantly when compared with the control sample, while BC was significantly effective in regard to increasing both DTPA-extractable Mn and hot water soluble B when compared with the control sample. Application of FYM and MC significantly increased DTPA-extractable Cu and Fe, respectively when compared with the control sample. Simple correlation and path coefficient analysis were performed to identify key chemical fractions of micronutrients in soil having the direct and indirect effects on availability of micronutrients in organically amended soils. Based on soil extractable concentrations of micronutrients in organically amended soils, FYM appeared to be the best source of Zn, Cu and Mn, while MC could serve as the best source of Fe. Biochar from Lantana sp. may serve as a good source of B.

    Opis:
    There exists an inadequate research on the propagation and nutrient needs of most tropical tree species. Hence, this work involves the developmental impact of soil amendments on the early growth of Streculia setigera Del. in the nursery. Different soil amendments; poultry waste (F1), goat manure (F2), cow manure (F3) and the control, normal soil (F4) were applied to several viable seeds of Streculia setigera in the nursery. The seeds were subjected to the same routine nursery practices. The experiment was laid in a Completely Randomized Design (CRD) and lasted for ninety (90) days. Descriptive statistics and ANOVA were used in the data analysis. The findings revealed that the entire growth response of Streculia setigera seedlings were only sparely affected by the soil amendments (P<0.05). F3 was found to be the most preferred soil amendment for this species, followed by F2 and F4 consecutively. The result obtained from F1 was very poor and thus it is not ideal for this species.

    Opis:
    Applying coffee grounds (CG) to sandy, calcareous, and clayey soils resulted in notable effects on soil expansion, cracking, cohesion, internal friction, initial stress and resistance to penetration. In sand, expansion upon saturation was greater after wetting-and-drying cycles. Highest increases were 15.71%, 16.14% and 31.86% for sandy, calcareous and clayey soils, respectively. Effect of CG on cracking was negligible in sand and very slight (<1.0%) in the calcareous soil but marked in clay (14.18% at 10% CG). In sand, cohesion (c) increased significantly with CG up to the 10% content. Cohesion increased by 2.5-folds and 4.5-folds at 5% and 10% CG, respectively. The presence of fine CG grains among larger sand particles, boosted microbial activities, and the resulting cementing and binding effects resulted in increased cohesion. For calcareous soil, cohesion rose from 0.04 kg·cm⁻² to 0.13 kg·cm⁻² as CG increased from 0% to 15%. In clay, maximum cohesion (0.20 kg·cm⁻²) was associated with the 10% CG and was highest of all soils. In sand, the angle of internal friction (φ) decreased notably as CG increased from 5% to 10% but there was no consistent pattern in any of the soils. An increase in initial stress (pi) was observed between 0% and 10% CG in sand and between 0% and 15% in calcareous soil while clay showed no particular trend. Patterns of pi were, thus, consistent with those of cohesion for all soils. Resistance to penetration increased substantially with CG in sand. The effect in calcareous and clayey soils took an opposite trend to that of sand and resistance was generally higher in calcareous soil. Overall effects of CG on resistance were desirable in all soils as far as agriculture (seedling emergence, crop growth, irrigation, etc.) is concerned.

    Opis:
    Coffee grounds (CG) improved some soil physical properties (dry density, gd; porosity, n; aggregation; hydraulic conductivity, Ks; and infiltration rate, IR). Effects on other properties were inconsistent (e.g., sorptivity, S), or unfavorable (e.g., available water, AW). gd decreased and n increased with CG. CG decreased Ks in sand. In calcareous soil, maximum increase was associated with 10% and 15% CG before and after wetting-and-drying cycles (WDC), respectively. Ks increased with CG in clay, with greatest increase attained at 10% CG. IR decreased with CG in sand. In calcareous and clayey soils, IR decreased with CG before WDC but increased after WDC where maximum increase in clay was linked to 10% CG. No solid trends of soil sorptivity, S, were identified. Before WDC, S had the order: sand > calcareous > clay. For most cases, adding CG increased total water holding capacity (WHC). However, after WDC, the increase in water content at field capacity (FC) with CG was accompanied by a greater increase in wilting point (WP) and therefore a decrease in AW. CG improved soil structure and aggregation and increased non-water-stable aggregates in calcareous and clayey soils. Mean weight diameter (MWD) indicated increase in water-stable aggregates in sand at 5% and 10% CG. In clay, MWD increased only at 5% CG. Although results did not show coherent responses with some tested properties, they, mostly, indicate some beneficial effects of CG, particularly in relation to improving aggregation and water flow.

    Opis:
    Waste disposal in landfills is one of most frequently used methods of municipal solid waste (MSW) management. Landfills disturb to a certain extent the landscape character and disposal of waste in landfils represents one of human activities that may impair natural ecosystems. Due to waste decomposition, numerous chemical, physical and biological reactions and changes occur within the landfill body that give rise to dangerous and harmful substances. One of the problems very often occurring in the landfill surrounding is soil contamination. This study is focused on the assessment of soils contamination due to the operation of sanitary MSW landfill. The aim was to determine the effect of diatomite and compost on soil phytotoxicity. Toxicity was assessed in a pot experiment with soil amendments. Soil samples (sample 1–4) for the experiment were taken from the landfill site (sample 1–3) and its surrounding (sample 4). The aim of this study was to check relation between soil amendments added to the soil sample and the amount of biomass produced by some plant species (Sinapis alba L., Hordeum vulgare L.). In this study soil amendments improved soil characteristics. The paper shows that a higher percentage of biomass weight increase was recorded in samples 1, 2, 3 and 4 with the addition of compost. As compared with the addition of diatomite, biomass weight in the samples with the added compost increased on average by 67.25%. Therefore, it can be stated that the addition of diatomite did not advance the plant growth as much as the addition of compost. The potential of using soil amendments in practice is promising.

    Opis:
    Abiotic and biotic stressors induce a strong cellular response in plants, resulting in significant changes in plant cells metabolism. Knowledge in this area can help to develop very specific methods of stress decrease. For this purpose, it is necessary to find sensitive and accurate tools that will allow to estimate the level of stress in cells. The largest group of substances involved in stress response are proteins. The study of changes in the protein profile can yield the most answers concerning the different mechanisms of soil microflora tolerance and the adaptation of plants to unfavorable conditions. The knowledge of these mechanisms can significantly support the assisted phytoremediation of soils. The aim of the study was to investigate the effect of abiotic factors on plant stress response in Lupinus luteus grown on soil contaminated with heavy metals and amended with organic additives. The aim of the study was to determine the level of plant stress based on tests of plant stress proteins presence and a specific peroxidase activity in plants grown on soil contaminated with heavy metals (HMs). An acrylamide gel electrophoresis (SDS-PAGE) has been used in the study to separate specific proteins fractions (metallothioneins), accompanying stress factors. The results of peroxidase activity indicated that the organic soil amendments have an impact on reducing plant stress. The lowest dose of soil amendments reduced the amount of peroxidase by almost half in roots. This proves that adequate soil supplementation helps plants to tolerate stress. The SDS-PAGE analysis suggests that in the most stressful conditions the protein profile is significantly different from control and indicates additional small protein products in the range of 7÷20 kDa indicating, in accordance with the literature, presence of metallothioneins as response to plant stress. The applied methodology confirms that organic soil amendments reduced the level of HMs plants stress after organic amendments soil application.
    Abiotyczne i biotyczne czynniki stresogenne wywołują silną odpowiedź komórkową u roślin, powodując istotne zmiany w metabolizmie komórek roślinnych. Pogłębienie wiedzy w tym zakresie może przyczynić się do opracowania metod zmniejszania reakcji stresowych roślin, a tym samym może zwiększyć odporność roślin na niekorzystne warunki glebowe. Konieczne jest więc stworzenie precyzyjnych narzędzi do szacowania poziomu stresu w komórkach. Największą grupę substancji zaangażowanych w reakcję na stres u roślin stanowią białka. Badanie zmian w profilu białkowym może dostarczyć odpowiedzi dotyczących poznania mechanizmów tolerancji mikroflory glebowej i przystosowania roślin do niekorzystnych warunków. Znajomość tych mechanizmów może w znacznym stopniu wpływać korzystnie na wspomaganą fitoremediację gleb. Celem pracy było zbadanie wpływu czynników abiotycznych na odpowiedź stresową roślin Lupinus luteus, uprawianych na glebie zanieczyszczonej metalami ciężkimi i wzbogaconej glebowymi dodatkami organicznymi. W pracy badano poziom stresu roślinnego na podstawie testów obecności roślinnych białek stresowych i aktywności peroksydazy w roślinach uprawianych na glebie zanieczyszczonej metalami ciężkimi (HM). W badaniu wykorzystano akryloamidową elektroforezę żelową (SDS-PAGE) do rozdzielenia frakcji białek roślinnych (metalotionein), towarzyszących czynnikom stresowym. Wyniki pomiaru aktywności peroksydazy wskazują na zmniejszenie stresu roślinnego, po wprowadzeniu do gleby zanieczyszczonej metalami dodatków organicznych. Najniższa dawka zastosowanych organicznych dodatków glebowych zmniejszyła aktywność peroksydazy o połowę w tkankach korzeni roślin. Dowodzi to, że odpowiednia suplementacja gleby pomaga roślinom tolerować stres. Wyniki analizy SDS-PAGE sugerują, że w najbardziej stresujących warunkach profil białka znacząco różni się od kontroli i wskazuje na pojawienie się dodatkowych, niskocząsteczkowych produktów białkowych w zakresie 7÷20 kDa. Zgodnie z dostępną literaturą, wyniki wskazują na obecność metalotionein w odpowiedzi na ekspozycję roślin na metale ciężkie. Przeprowadzone badania potwierdzają, że wprowadzone do gleby zanieczyszczonej metalami ciężkimi dodatki organiczne, zmniejszyły wskaźniki stresu roślinnego.
