The aim of this study was to evaluate and compare the competitive and individual sorption of Cd, Cu, Pb and Zn on three natural soils: a Gleyic Fluvisol (content of Cd 30, Cu 25, Pb 2297 and Zn 3718 mg/kg), a Gleyic Cambisol (content of Cd 5, Cu 29, Pb 1158 and Zn 180 mg/kg) and a Chernozem (content of Cd 0.4, Cu 36, Pb 75 and Zn 67 mg/kg). For evaluation of the sorption and desorption, the Freundlich isotherms were used. The results of the model experiment confirmed that the sorption from single-metal solution was more effective than sorption under multi-metal conditions, due to competitive effects. In all tested soils sorption of Cd, Cu and Zn decreased...

Flooding caused by intensive precipitation has been in the centre of attention of both general public and scientists. From the flood risk management perspective, an integrated approach to catchment management is necessary, in particular with regards to water retention capacity. Our research has been focused on the high intensity rainfall, its short duration, and an adequate infiltration capacity into the soil profile in the upper parts of the catchment, the same as on the impact of soil characteristics such as moisture content and suction pressure, in particular. The five-year research period in two sub-catchments - Červík A and B - in the Beskydy...

One of the most important binding agents for forming stable aggregates is a soil organic matter (SOM), which can be retained in various size fractions of aggregates. If aggregates are water-resistant, they retain more carbon. Therefore, the aim of this study was to evaluate the stability of aggregates and their ability of carbon sequestration in different soil types and soil management systems in Slovakian vineyards. The highest content of water-stable macro-aggregates (WSAma) was determined in Cambisols, and the lowest in Fluvisols. The highest content of WSAma (size fraction 0.5-3 mm) was determined in Chernozems, decreasing...

A pot experiment was conducted to study interactive effects of arbuscular mycorrhizae (AMs) and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon (C) storage in a sterilized sandy loam soil. The experiment included four treatments: control, inoculation with AM fungus Glomus caledonium (M), amendment with maize straw (S), and amendment with maize straw plus inoculation with G. caledonium (S + M). The inoculation of G. caledonium significantly (P < 0.05) increased wheat root biomass and root-to-straw ratio, but had no significant effects on shoot biomass, grain...

Irrigation with treated wastewater is essential for increasing crop production in arid and semi arid regions. Field experiments were conducted on rainfed clayey soil to investigate the impact of water quality, cultivation, and different cropping systems on cumulative infiltration (F(t)), field saturated hydraulic conductivity (HCfs), penetration resistance (PR), and water stable aggregates (WSA). Treatments were: (1) barley fields tilled for the past 20 years (CB-T), (2) olive tree fields tilled for the past 20 years (CO-T), (3) non-cultivated field for 20 years, tilled for the...

The efforts to introduce the micro irrigation system in Iran go back as far as the year 1990. The area under micro irrigation system in Iran covers about 400 000 ha and it is estimated to double (800 000 ha) during the next five years. The field performance of micro irrigation systems was studied in ten Iranian sites. Physical, chemical, and biological analyses of water samples derived from each site included pH, electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), Fe, Mn, Mg, Ca, and bacterial number (BN). In this study relative emitter discharge (R), percentage of completely clogged emitters (Pclog),...
