The impact of a bottom sediment on the reaction and the content of exchangeable aluminium in a soil

The aim of the study was to determine the effect of bottom sediment on the pH and content of available forms of P, K, Mg and aluminium exchangeable in the soil and on the yield of oats.The research was carried out in the Podlasie voivodship on very light soil. The material for the tests were samples of bottom sediment. In the experiment a bottom sediment from the breeding pond and soil was used. In the sediment bottom sediment sam-ple, the following parameters were determined: pH, heavy metal content (lead, cadmium, zinc, copper), as well as the content of aluminum, phosphorus, potassium and magnesium. The reaction of the bottom sediment was also determined. In soil samples, the content of exchangeable aluminium, available forms of phospho-rus, potassium, magnesium was determined and the soil reaction was determined. The obtained results confirmed the influence of bottom sedi-ment on reducing the content of exchangeable aluminium in the soil. The analyzes show that the soil after application of bottom sediment contained significantly less exchangeable aluminium. The sludge also influenced the increase of soil pH and the incre-ase of magnesium content in the soil. There was no influence of the use of bottom sediment on the content of available phospho-rus and potassium in the soil and on oat yield

Use Bottom Sediment to Agriculture—Effect on Plant and Heavy Metal Content in Soil

Removing bottom sediment from water reservoirs and rivers can, on the one hand, be an effective method to restore lakes, and on the other—be used for plant production, ensuring the recycling of nutrients. The aim of this research was to evaluate the possibilities of using various types of bottom sediment and its impact on heavy metal content in soil and plants. For this purpose, a pot experiment was carried out using white mustard (Sinapis alba) as a test plant. The total content of heavy metals (Cd, Cu, Zn, Pb) was determined in soil and plant. The addition of all types of bottom sediment increased heavy metal content in the soil. The results indicate that adding bottom sediment resulted in a significant increase in plant yield in comparison to the control. The highest yield as a result of direct effect was obtained for a combination with a 5% addition of dam sediment, while as a result of residual effect, the highest yield was achieved for a mixture with a 10% addition of pond sediment. The values of the transfer factor (TF = Cplant/Csoil) indicate a high accumulation of zinc and low accumulation of lead in the plant

The impact of diverse level of manure application on the chemical properties of the soil

The aim of this study was to determine the effect of various methods of introducing manure in to the soil on the chem- ical properties of the soil. The field experiment was carried out in the Podlasie voivodship on a sandy soil. Cattle manure was ap- plied in a dose of 30 Mg ha-1 and mixed with the soil using a disc harrow or plowed into the depth of 10 and 20 cm. In soil samples, the content of available forms of phosphorus, potassium, mag- nesium, copper, sulfur, boron, manganese, zinc, iron and the soil reaction was determined. The results confirmed the influence of depth of manure application on soil properties. As the cultivation depth increased, the content of phosphorus and organic carbon in soil increased, C/N ratio expanded, but the content of magnesium and potassium in soil decreased. No effect of the cultivation depth on the soil pH value and the content of nitrogen, boron, zinc and sulfur was found. The results of the study indicate a different rate of manure changes in soil and the related need to develop ferti- lizer equivalents depending on the manure application method

Patterns of oral anticoagulant use and outcomes in Asian patients with atrial fibrillation: a post-hoc analysis from the GLORIA-AF Registry

Background: Previous studies suggested potential ethnic differences in the management and outcomes of atrial fibrillation (AF). We aim to analyse oral anticoagulant (OAC) prescription, discontinuation, and risk of adverse outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods: From the GLORIA-AF Registry Phase II-III (November 2011-December 2014 for Phase II, and January 2014-December 2016 for Phase III), we analysed patients according to their self-reported ethnicity (Asian vs. non-Asian), as well as according to Asian subgroups (Chinese, Japanese, Korean and other Asian). Logistic regression was used to analyse OAC prescription, while the risk of OAC discontinuation and adverse outcomes were analysed through Cox-regression model. Our primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). The original studies were registered with ClinicalTrials.gov, NCT01468701, NCT01671007, and NCT01937377. Findings: 34,421 patients were included (70.0 ± 10.5 years, 45.1% females, 6900 (20.0%) Asian: 3829 (55.5%) Chinese, 814 (11.8%) Japanese, 1964 (28.5%) Korean and 293 (4.2%) other Asian). Most of the Asian patients were recruited in Asia (n = 6701, 97.1%), while non-Asian patients were mainly recruited in Europe (n = 15,449, 56.1%) and North America (n = 8378, 30.4%). Compared to non-Asian individuals, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian patients (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively), but higher in the Japanese subgroup. Asian ethnicity was also associated with higher risk of OAC discontinuation (Hazard Ratio [HR] and [95% CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95% CI]: 0.86 [0.76-0.96]). Among the exploratory secondary outcomes, Asian ethnicity was associated with higher risks of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding. Interpretation: Our results showed that Asian patients with AF showed suboptimal thromboembolic risk management and a specific risk profile of adverse outcomes; these differences may also reflect differences in country-specific factors. Ensuring integrated and appropriate treatment of these patients is crucial to improve their prognosis. Funding: The GLORIA-AF Registry was funded by Boehringer Ingelheim GmbH
