Soil erosion and terrestrial deposition of soil organic carbon (SOC) can potentially play a significant role in global carbon cycling. Assessing the redistribution of SOC during erosion and subsequent transport and burial is of critical importance. Using hydrological records of soil erosion and sediment load, and compiled organic carbon (OC) data, estimates of the eroded soils and OC induced by...

(The survival and establishment potential of spores of Cyathea delgadii Sternb. in soils from Itirapina and Moji Guaçu (SP), Brazil). Germination of spores of Cyathea delgadii was carried out in soils collected in March 1997 (rainy season) at three depths (0-5, 5-10 and 10-15 cm) from the cerrado, open-cerrado, gallery forest and marsh at Moji Guaçu and cerradão, cerrado and gallery forest at P...

In the 1990s and early 2000s, there was widespread pessimism on the status of soil science in most parts of the world. This was mainly due to dwindling research budgets, reduced number of students and the overall perception that soil science and pedology were dead and buried. Renewed interest in agriculture for food, feed and fuel has brought soils back onto the global research agenda. Soil ero...

In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results  in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, doub...

The soils of the McMurdo Dry Valleys, Antarctica are an extreme polar desert, inhabited exclusively by microscopic taxa. This region is on the threshold of anticipated climate change, with glacial melt, permafrost thaw, and the melting of massive buried ice increasing liquid water availability and mobilizing soil nutrients. Experimental water and organic matter (OM) amendments were applied to i...

TNT is released into the soil from many different sources, especially from military and mining activities, including buried land mines. Vegetation may absorb explosive residuals, causing stress and by understanding how plants respond to energetic compounds, we may be able to develop non-invasive techniques to detect soil contamination. The objectives of our study were to examine the physiologic...

Buried wood is an important yet understudied component of natural and anthropogenic soils. Nutrient immobilization as a response to addition during oil sands' reclamation may be concern since surface salvaged with the soil, thereby becoming buried in cover This project investigated impact on macronutrient supply microbial communities different A 60-day incubation was performed rates types (0%–5...
