The anion-exchange resin (AER) method for the estimation of bioavailable phosphorus was slightly optimised for soils with high contents of readily soluble organic compounds as well as for those having very different clay and sand contents. The method based on a strong base anion exchanger, the active group of trimethyl benzyl ammonium, the field moist soil, and the enclosure of resin beds in a bag was very different soils under relatively uniform outer conditions where the determination of the absorbance of (blue) phosphate-molybdate complex at 870 nm is used. The motivation of the proposed method comes from distinctive features of forest soils where...
Difference in Canopy and Air Temperature as an Indicator of Grassland Water StressOriginal Paper

Soil & Water Res., 2006, 1(4):127-138 | DOI: 10.17221/6514-SWR
In 2003-2005 in conditions of the moderately warm region of the Třeboň Basin (Czech Republic) the difference between canopy temperature (Tc) and air temperature at 2 m (Ta) was tested as an indicator of grassland water stress. To evaluate water stress ten-minute averages of temperature difference Tc-Ta were chosen recorded on days without rainfall with intensive solar radiation from 11.00 to 14.00 CET. Water stress in the zone of the major portion of root biomass (0-0.2 m) in the peak growing season (minimum presence of dead plant residues) documented by a sudden increase in temperature difference, its value 5-12°C and unfavourable canopy temperatures...
Optimisation of Irrigation Regime for Early Potatoes, Late Cauliflower, Early Cabbage and CeleryOriginal Paper

The paper deals with optimisation of threshold suction pressure of soil water on light soils for early potatoes, early cabbage, late cauliflower and celery on the basis of results of small-plot field experiments with differentiated irrigation regime. Experiments were conducted in 2003-2005. Threshold suction pressures of soil water were identical for all crops: 15 kPa in treatment I, 30 kPa in treatment II, 60 kPa in treatment III, and 120 kPa in treatment IV. Precipitation, air temperature and relative humidity, global solar radiation, wind speed and direction were measured by an automated meteorological station. Reference and actual evapotranspiration...

In this study were compared heterotrophic respiratory potential (VDS/VMAX) expressing an increase in C mineralisation rate after drying and re-wetting the soil to 60% soil water content (v/w)(VDS) in relation to maximum respiration rate (VMAX) after glucose addition, and VMAX in organomineral soil (Ah horizon) of moderately mown and for 11 years abandoned mountain meadows in Moravian-Silesian Beskids Mts. VDS/VMAX and VMAX were assessed in soil samples taken in 30-day intervals throughout the period of May-September 2004. The results obtained showed higher VDS/VMAX on the abandoned meadow throughout the whole experiment except the last sampling occasion,...

Environmental pollution of heavy metals from automobiles has attained much attention in the recent past. The present research was conducted to study heavy metal contamination in roadside soils of northern England. Roadside soil samples were collected from 35 sites in some counties of northern England and analysed for four heavy metals (cadmium, copper, lead, zinc). Their concentrations and distributions in different road verge zones (border, verge, slope, ditch) were determined. Lead concentration was the highest in the soil and ranged from 25.0 to 1198.0 μg/g (mean, 232.7 μg/g). Zinc concentration ranged from 56.7 to 480.0 μg/g (mean, 174.6...
