Sensitivity of soil respiration and microbial communities to altered snowfall
Winter respiration is a quantitatively important, yet variable flux of carbon dioxide (CO2) from soils to the atmosphere. Variability in winter soil respiration may be influenced by the effects of snowfall on microbial communities and their metabolic activities. In this study, we evaluated the importance of snowpack depth on soil respiration and microbial communities in a temperate deciduous fo...
متن کاملHeavy metal Impact on Soil Microbial Biomass , Soil dehydrogenase activity and Soil Respiration rate
The contamination of agricultural soils by heavy metals is a global problem. Soil texture as a biotic factor represents one of the most important factors that influences the distribution of organic matter and ultimately play decisive role in retention of heavy metals in soil ecosystem. The effects of heavy metals on soil microbial processes were investigated. Analytical grade sulphate and chlor...
متن کاملThermal adaptation of soil microbial respiration to elevated temperature.
In the short-term heterotrophic soil respiration is strongly and positively related to temperature. In the long-term, its response to temperature is uncertain. One reason for this is because in field experiments increases in respiration due to warming are relatively short-lived. The explanations proposed for this ephemeral response include depletion of fast-cycling, soil carbon pools and therma...
متن کاملImpact of soil drying-rewetting stress on microbial communities and activities and on degradation of two crop protection products.
Prior to registration of crop protection products (CPPs) their persistence in soil has to be determined under defined conditions. For this purpose, soils are collected in the field and stored for up to 3 months prior to the tests. During storage, stresses like drying may induce changes in microbiological soil characteristics (MSCs) and thus may influence CPP degradation rates. We investigated t...
