	abstract = {Abstract In this study, the Natura 2000 nature protection network of the European Union is assessed in the context of soil quality management. We explore the hypothesis that the soil quality of croplands and grasslands — as indicated by soil organic carbon and phosphorus levels — is better in terms of environmental parameters within the Natura 2000 network than outside it. The soil organic carbon and phosphorus content of 479 cropland and 450 grassland sites within Natura 2000 were compared with their nearest neighbours outside the network. The comparisons were repeated for pairs of both cropland and grassland sites by soil texture groups. The study revealed that organic carbon content was significantly higher in Natura 2000 sites than in non-protected areas for both croplands and grasslands. For croplands, this was true only for those with signs of ploughing, whereas for croplands without signs of ploughing there were no significant differences between Natura 2000 and non-protected areas. Areas with sand and loamy sand soils had significantly higher soil organic carbon content within the Natura 2000 network than outside it, for both croplands and grasslands. This was the only texture class that showed a significant difference in the case of croplands, whereas three further texture groups had higher soil organic carbon content in Natura 2000 grassland sites than on grassland sites outside this network. There was no significant difference in soil phosphorus content between areas within the Natura 2000 network and non-protected areas, except for grasslands with light textured soils, where soil phosphorus levels were significantly lower within Natura 2000 sites than outside them. The results suggest that the management of croplands and grasslands of Natura 2000 sites tends to perform better than that of adjacent areas with similar land cover in terms of soil carbon conservation. The difference is more evident for sites with certain soil characteristics. On the other hand, the nutrient input - as determined by phosphorus levels - of Natura 2000 croplands and grasslands generally does not appear to be less intensive than that of surrounding areas outside the network.},

	abstract = {In this chapter, exchange dynamics of greenhouse gases over Hungarian grassland ecosystems are analyzed. Carbon dioxide (CO2) exchange was measured by eddy covariance technique at three sites (Bugac, Mátra, and Hegyhátsál). Methane (CH4) and nitrous oxide (N2O) fluxes were occasionally measured by static chamber method partly at the same grassland sites and at a wetland site. Dry grasslands (Bugac and Mátra) were net sources of CO2 in extreme drought years on annual time scale, while in other years they acted as sinks. The relatively humid Hegyhátsál was a net sink of CO2 on annual time scale during the measurement period. The different soil types (light sandy soil, heavy clay soil, and loamy soil) and the variable amount of annual precipitation sums (ranging from 551 to 747 mm) provided a unique opportunity to analyze the response of CO2 dynamics of grasslands to the soil type and effect of water stress. In case of the sandy grassland (Bugac), the exclusive role of the annual precipitation sum in the determination of annual NEE is strongly coupled to the soil type. Although the sandy grassland expressed adaptation to drought, the CO2 sink--source precipitation threshold was within the standard deviation (112 mm) of the annual precipitation, showing the high risk of desertification in this ecosystem. Grassland ecosystem on heavy clay soil was more vulnerable to drought stress than the grassland on sandy soil due to the worse water management properties of the clay soil. At the grassland on loamy soil in the more rainy western part of the country, gross primary production was occasionally limited by high soil water contents. This grassland has good adaptation capabilities to uneven precipitation distribution owing to the high silt fraction of the soil resulting in high water storage capacity. CH4 flux above grasslands was within the range of −54 to 58 mg CH4 m−2 year−1 (negative flux means uptake by the soil). Wetland soils are generally CH4 emitters. Annual mean of N2O soil emission varied between 0.005 and 0.17 g N2O m−2 year−1 with 6-year averages of 0.08 and 0.03 g N2O m−2 year−1 for sandy/loess and clay soils, respectively. Mean soil flux of N2O over wetlands was similar to N2O emission over dry grasslands.},
