(M/MF155) Monitoring of soil management and soil biological parameters for soil quality assessment in viticulture. Reuter, Stephan1, Kubiak, Roland1, 1 ABSTRACT- In viticulture weed control is a dominating part of soil management. The various systems for weed control like mechanical or chemical techniques, mulch or green cover have different effects on the soil environment. Additionally, in vineyards the permanent single-crop cultivation and rigid trellis systems promote the use of different soil management systems within short distance which can produce a high spatial heterogeneity of soil parameters. Soil management systems had often been regarded only in point of view of their efficacy for weed control. Today effects of cultivation on soil ecological parameters were placed into the foreground. In order to investigate the environmental impact of soil cultivation under the particular situation of viticulture, in this work biological parameters are used for quality assessment of vineyard soils. For this, soil samples were taken from vineyards with different soil management systems like cultivation, green cover, mulching or herbicide application. The samples were analyzed for different soil microbial parameters. Vineyards cultivated according to ecological viticulture are of particular interest because the adequate soil management has priority to support soil health. The results indicated the influence of both soil type and soil management on soil microbial properties. Therefore, quality parameters of soil biology should be established to characterise the effects of different soil management systems and soil physical and chemical properties on soil biology, and to support soil quality for sustainable land use. In addition to the field observations the data base of vineyard site characterisation (description of soil type, soil physical and chemical data) provides a useful tool to characterise the potential of soil quality in viticulture. Key words: soil biology, soil quality, soil management |
