  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • Distribution of organic carbon in soil profile data

    Soil organic carbon (SOC) content has been estimated at pan-European scale for the soil layer from 0 to a depth of 30 cm (Jones et al., 2005). The methodology used to generate the data layer relied on a combination of a pedo-transfer rule (PTR) and pedo-transfer functions (PTF). The PTR has been developed based on PTR No. 21 of the PTR database of the Soil Geographic Database of Eurasia (SGDBE). ...


  • Transcriptional profiling of the soil invertebrate (Folsomia candida) in pentachlorophenol contaminated soil

    Pentachlorophenol (PCP) as a widely used pesticide is also considered to be an endocrine disruptor. Molecular effects of chemicals with endocrine disrupting potential on soil invertebrates are largely unknown. In this study we explored the transcriptional expression changes of collembola (Folsomia candida) in response to PCP contamination. A total of 92 genes were significantly differentially ...

  • Uncertainty and sensitivity analysis of water transport modelling in a layered soil profile using fuzzy set theory

    A methodology based on fuzzy set theory is presented to express imprecision of input data in a non-probabilitic sense. Imprecision may originate from indirect measurements, estimation routines, subjective interpretation, and expert judgement of available information. A numerical finite difference solution scheme was chosen to solve one-dimensional steady-state water flow in the unsaturated zone ...

  • Describing soils: Calibration tool for teaching soil rupture resistance

    Rupture resistance is a measure of the strength of a soil to withstand an applied stress or resist deformation. In soil survey, during routine soil descriptions, rupture resistance is described for each horizon or layer in the soil profile. The lower portion of the rupture resistance classes are assigned based on rupture between thumb and forefinger. The tactile sense of the pressure can vary ...

  • Integration of the soil database of Turkey into European soil database 1:1.000.000

    The first soil map of Europe was published at 1970 (Dudal et al., 1970). In 1985, the Commission of the European Communities (EC) published the soil map of the EC at 1:1,000,000 scales (CEC, 1985). In 1986, this map was digitised (Platou, Nørr and Madsen, 1989) in order to build a soil database and furthermore to be included in the CORINE project (Co-ordination of Information on the Environment). ...
