    The current status of soil organic matter in the Czech Republic (including all positive or negative impacts on soil properties)

  • Original language description

    A recent study reviewing the current status of soil organic matter in the Czech Republic, namely the oxidizable carbon (Cox) content, is presented. In the Czech Republic, there is no system of regular soil monitoring focusing on SOM. Some historical data on the soil content of oxidizable carbon (Cox) are available from the ‘Comprehensive Soil Survey’ conducted from 1961 to 1971. More recently, the Research Institute for Soil and Water Conservation has conducted so-called ‘retrospective’ soil monitoring in selected areas of the historical Comprehensive Soil Survey and repeated the determination of selected soil characteristics (mostly those linked with climate change predictions), including Cox content. Presently the typical content of oxidizable carbon (Cox) is: 1.3 – 1.9% in modal black soils; 1.4 – 1.6% in modal brown soils; 1.0 – 1.3% in modal cambisols; and 1.2 – 2.5% in modal pseudo-gley soils. Based on a comparison of the historical data and these current analytical results, a decline of oxidizable carbon (Cox) has been detected in virtually all kinds of soils (with the exception of black soils) in both main horizons (i.e. in the topsoil and subsoil). A decline of soil organic matter (SOM) refers to a loss of organic matter (both in mass and quality) in soils over time. This may lead to: a deterioration of soil structure and increased soil erosion; reduced water and nutrient retention; reduced biological activity of soils with negative effects for plants and soil macro- and microorganisms; and to a reduced efficiency in water and nutrient use by plants. There is some evidence that climate change can also contribute to a decline in SOM. All these factors are real risks for the future development of soil fertility and crop production in the Czech Republic.
