MUBIL III – Evaluation, Subproject: Influence of hedgerows on microclimate on field crops
Abstract
The optimisation of local-climatic and microclimatic relations by creation of landscape elements (e.g., windbreak arrangements, hedge structures) is an essential aspect in organic farming. Thus the changed microclimate in and near hedges has big effect on the attraction of the living space hedge and fulfils an important ecological niche function (e.g., for useful animals). Furthermore it has a positive effect on plant stocks and can change the local conditions (example the water balance due to changing rates of evapotranspiration, the wind field and dew, etc.) for crop production and ecology decisively which is known from many studies, for example in Agro-Forestry systems (e.g., Benzarti, in 1999; Cleugh, in 1998; Eastham and rose, in 1988; FAO, in 1962; Lin et al., in 1999; Boahua et al., in 2000). However, hedges or high crops also show significant climatic island effects (e.g. Eitzinger and Kössler, in 2002; Groot and Carlson, in 1996; McAneney et al., in 1990), they soften the climatic extremes of the free field conditions and fulfil an important ecological function beside the known protective function against wind and erosion.
