In parts of the world, Se availability in the soil is so low that Se contents in the crops produced there are well below recommended values. Since the difference between Se essentiality and toxicity is very small, the addition of Se via fertiliser is controversial. Therefore, it is important to utilise the Se added in the best possible way. The objective of the present study was to investigate the influence of soil organic matter on the one hand, and addition of organic material (slurry) on the other hand on plant availability of selenium (Se) in soil. Pot experiments with the Se addition in the form of selenate were conducted with a peat, a loam and a peat/loam mixture at a range of pH values between 5 and 6.8. Se uptake from added Se fertiliser was higher in the soil types with high organic matter content than in the loam at pH 6 and below. The opposite occurred at a soil pH above 6.4, where Se uptake was higher in the loam than in the peat. In a pot experiment using only peat and loam at two pH levels, cattle slurry added together with selenate was found to increase the Se concentration in grain at the higher pH. At the lower pH there was no significant effect of slurry on Se concentration in grain. Application of slurry also increased the residual effect of Se that had been applied to the loam in the preceding growing season. In the peat, no residual effect of Se was found either with or without the addition of slurry.

Norway has strong and competent institutions and lobby organisations for hydro and oil/gas. It has been difficult for renewables to reach the political agenda. The situation in 2007 is quite different compared with 10 years ago, now the knowledge about and political power of bioenergy is improved. The demonstration value of the Gardermoen project and the informational, educational and public relations work of the Energy Farm are important contributions to this changed situation. Climate change is of course another factor of large importance. The two case-studies, Gardermoen bioenergy plant and the Energy Farm, demonstrate that there are many other factors that prices/costs that influences bioenergy implementation.

This paper aims to provide an overview of experience for sustainable water management in Norway. It covers professional areas of integrated water management including urban stormwater management, hydropower development and environment protection, hydrological data collection and flood control, soil erosion and control measures from agricultural areas, ecosystem conservation in river catchments and sediment transportation, and the long-term development of climate change. Water management should be systematic and predictable, and based on the principle of legality. Selected central acts regulating water management aspects, important regulations including regulations on drinking water, sewage purification, licence fees, safety and supervision of watercourse installations were reviewed. The recognition of the economic value of water is visible in many parts of Norwegian water legislation. Several aspects of urban stormwater management, as a whole of integrated water management, were highlighted in part 1 of the paper. Hydropower development related regulations concerning on environment protection were described in part 2. Floods caused by typical climate in Norway, structural and non-structural measures to mitigate floods were summarised in part 3. Erosion from agricultural areas, control measure, monitoring system were summarised in part 4. Research regarding erosion process in river catchments, glacial erosion, and erosion in clay areas, mountain and arctic rivers, and sediment transportation in rivers were presented in part 5. Climate development in Norway during 1900-2100 was given in the last part of the paper, where regional climate downscale models, empirical and dynamical downscaling, were introduced. Results of climate variation - temperature and precipitation in Norway in the latest 100-150 years and scenarios of climate development during the 21st century were presented.

Abstract
A main scourge in Norwegian sheep farming is tick-borne fever (TBF) caused by the bacteria A. phagocytophilum and transmitted by the tick Ixodes ricinus. The aim of this poster is to present a new research project on resistance to TBF in sheep (2007?2010).
