Combining seismic and electric methods for predicting bedrock depth along a Mediterranean soil toposequence

DIVISION S-3—SOIL BIOLOGY & BIOCHEMISTRY Soil Nitrogen, Microbial Biomass, and Respiration along an Arctic Toposequence

than other regions of the world (Mitchell et al., 1990; Maxwell, 1992). Summer air temperatures in northern To investigate the interactions among mineral N, C availability, Alaska are predicted to increase 3 to 68C over current microbial biomass, and respiration in arctic soils, we sampled soils five times during a growing season from a toposequence on a slope levels, whereas precipitation duri...

Predicting Soil Erosion With RUSLE in Mediterranean

Accurate assessment of soil loss is essential for sustainable agricultural production, 11 management and conservation planning, especially in productive rain-fed agro-ecosystems 12 and protected areas. The European Union considers soil as a non-renewable resource and 13 identifies that soil degradation has strong impacts on soil and water resources. In this work the 14 Revised Universal Soil Lo...

Mobility of Natural Radionuclides and Selected Major and Trace Elements along a Soil Toposequence in the Central Spanish Pyrenees

Natural gamma-emitting radionuclides (U, Ra, Th, Pb) and selected major and trace elements (Ca, K, Mg, Na, Fe, Al, Mn, Pb, Ba, Zn, Sr, Li, Co, Ni, Cu, Cr, Cd) were determined in a soil toposequence along a mountain slope of the Tertiary Flysch landscapes in the Central Spanish Pyrenees. A variety of basic properties were also measured from the soil profiles. Mean radioisotope activities (Bq kg ...

Long-term Fertilization Structures Bacterial and Archaeal Communities along Soil Depth Gradient in a Paddy Soil

Soil microbes provide important ecosystem services. Though the effects of changes in nutrient availability due to fertilization on the soil microbial communities in the topsoil (tilled layer, 0-20 cm) have been extensively explored, the effects on communities and their associations with soil nutrients in the subsoil (below 20 cm) which is rarely impacted by tillage are still unclear. 16S rRNA g...
