Significant Difference

Studies on the CO2 and N2O emission patterns of agricultural soils under different ploughing practices may provide an insight into the potential and magnitude of CO2 and N2O mitigation in highly managed farmland soils. In this study, field measurements of soil respiration and N2O flux with different ploughing depths were performed in the 2003–04 wheat (Triticum aestivum L.), 2004 maize (Zea mays L.), and 2004–05 wheat seasons. Soil temperature and moisture were simultaneously measured. Results showed that, in each cropping season, the seasonal variation in soil respiration developed with a similar pattern for different treatments, which was primarily regulated by soil temperature. This work demonstrates that ploughing depth can influence long-term loss of carbon from soil, but this was contingent on preceding cropping types. Given the same preceding cropping practice, no significant difference in N2O emission was found among different ploughing depths in each cropping season.

Index Method

To identify the concentration and spatial distribution of cadmium (Cd) in agricultural soils, 207 soil samples were collected from Chaoyang and analyzed based on pollution index methods and GIS. The concentration of Cd in the soils of Chaoyang ranged from 0.030 to 0.687 mg/kg, with an average concentration of 0.246 mg/kg. The evaluated results of Cd in agricultural soils of Chaoyang shows that the pollution excess rate is 2.90%, the total agricultural soil environment of Cd was still clean, but some areas were accumulated by Cd. The differences between two evaluated methods indicate that evaluated criteria had a direct impact on the evaluation results, compared to integrated pollution index, the Geoaccumulation index method was more accurate and objective.

SummaryWe have analyzed the loss of agricultural land in a case study of the community Eggelsberg in the Innviertel in Upper Austria. The trigger for the project was the attribution of Austria as Europe’s leader in soil sealing. We compared the results of the Austrian agricultural soil survey of the 1970s with the actual land use and quantified the land use change. Within half a century, 15% of the agricultural area was converted to settlement area or to other forms of infrastructure. According to the original soil assessment, 96 ha of high-quality cropland, 1,220 ha of medium-quality cropland, 121 ha of low-quality cropland, and 409 ha of grassland were converted. The forest cover remained stable. The highest share of soil sealing was owed to the expansion of the settlement area and the construction of a successful enterprise. Minor contributions were expansions of farm buildings. The loss of agricultural land was reasonable and reflected the needs of the local population. A special protection status because of the future relevance of the agricultural land was not communicated to land managers and is not reflected in the market prices of agricultural products. The relevance of the agricultural land beyond the regional level is not fully recognized.
