The goal of this work is to present a suitable tool or model for the evaluation of the internal landfill water discharge, in relation to the basic design parameters of internal landfill drainage system and other processes. De Zeeuw-Hellinga's drainage theory fulfils those requirements. De Zeeuw-Hellinga's drainage intensity factor takes in basic design parameters of internal landfill drainage system and also hydro-physical properties of the collected waste. The drainage theory calculates with landfill internal water recharge to the drainage system within a certain time interval. In practice this method was successfully verified in a sanitary landfill...

The objectives of our study were to apply, test and to present the ability of the deterministic simulation model SIMWASER computing soil-water balance components. Two case studies for the assessment of percolation losses from irrigated carrots to deep groundwater at Obersiebenbrunn in the Marchfeld (Austria) and ground water recharge and capillary rise from shallow groundwater in grass lysimeters at Berlin-Dahlem (Germany) are presented to demonstrate the performance of the model by a comparison between measured and simulated results from the field experiments. At Obersiebenbrunn, simulated percolation and evapotranspiration were 183 and 629 mm, while...

The response of antioxidant enzymes and quality of three soybean varieties to Mo and/or B in soil has been studied in this paper. Pot experiments were set up with four treatments (control, +Mo, +B, +[Mo + B]) at four growth stages. The study showed that Mo and/or B increased antioxidant enzyme activities and protein content in the seeds. The variation and interaction between Mo and B in soil was explored with regard to their impact on the soybean quality. The Mo and/or B decreased oil-content, linoleic and linolenic acid and thus improve plant quality for human health. There were some dissimilarity in antioxidant enzymes and quality of plant between...
Effect of enzymatic activity of diesel oil contaminated soil on the chemical composition of oat (Avena sativa L.) and maize (Zea mays L.)

Plant Soil Environ., 2005, 51(8):360-367 | DOI: 10.17221/3611-PSE
The aim of the study was to determine the effect of soil contamination with diesel oil (3, 6, 9, 12 and 24 g/kg soil) on the yield and the content of macroelements in oat and maize cultivated in soil supplemented with nitrogen and sawdust. The correlation between the content of macroelements in the crops and the soil enzymatic activity was also determined. High doses of diesel oil had a definite negative effect on the content of all macroelements in oat, excluding phosphorus. The presence of diesel oil had a favourable effect on the accumulation of most of macroelements in the above-ground parts of maize. Nitrogen application to the soil caused an...
Influence of gypsum treatment on extractability of nutrients from soils

In an incubation experiment with 36 soils we tested the influence of application of 3.3 g of CaSO4.2 H2O per kg of soil on extractability of nutrients (P, K, Mg, Ca, Mn, B and S). After 134-day incubation of gypsum-treated soils the soils were extracted with water (1:5, w/v), 0.5M ammonium acetate with NH4F addition (pH 7) and by Mehlich 3 method. An ICP-technique was used for nutrient detection and colorimetry on a SKALAR analyser was employed to determine phosphates and sulphates. The most interesting results were measured in phosphorus. P concentration was markedly lower in the H2O extract after gypsum...
Particular aspects of environmental impact of potentially risk elements from airborne particulate matter

Two simple experiments were carried out to demonstrate two possible ways of environmental impact of element contents in airborne particulate matter. In the first part of the experiment, the response of three rural dust samples applied into the soil were assessed in pot experiment to observe uptake of As, Cd, Pb, and Zn by aboveground biomass of oat (Avena sativa L.). Although the element contents in dust samples exceeded significantly total element contents in soil, the element content in plants was not affected by single-rate soil amendment with rural dust sample. Soil sorption capacity and neutral pH of the experimental soil (7.0) was sufficient...
