Development of a substrate material for trees in the city of Vienna

Within this project the currently used substrate for trees in Vienna will be analysed and optimised regarding its water and air balance. Additionally the strain for the substrate of de-icing salt will be investigated. For this purpose controlled field experiments will take place .

The following questions shall be clarifyed: Which substrate is suitable for an improved water and air balance in the soil? What is de-iceing salt doing in the soil? Do mycorrhiza have impact on the development of trees?

The Soil Strategy Network in the Danube Region is funded by the European Union (European Regional Development Fund). Its main aim is to develop a sustainable soil network for the Danube region and improve soil awareness. Partners from different sectors such as research, agriculture, administration, art, education as well as a broad public are involved.

Within this project we perform a soil erosion assessment for a model region in the Weinviertel region, near to the city of Hollabrunn. Additionally, the historical development of soil erosion in this region will be investigated starting with about 1822 until now. A catalogue of measures will be provided to improve land use.

Mass balance of organic carbon at catchment scale

For an intensive agricultural land cultivation a sustainable land use and especially a sufficient supply of nutrients is essential. Decrease of organic carbon leads to a degradation of many soil functions. Therefore a well balanced organic carbon mass balance is of great importance for a sustainable water and soil protection.

The main aim of this project is the identification of basic information for reconstructing a mass balance of organic carbon at catchment scale. Therefore relationships between soil erosion and the loss of organic carbon will be examined.
