The term “terra rossa” comes from the Italian for “red soil” or “red earth”. Although terra rossa exists in other places in the world, these soils are common in areas with Mediterranean-type climates: alternation of a rainy and cool-to warm-dry season. The terra rossa soil is heavy and clay-rich (silty-clay to clayey) soil, strongly reddish, …[Read More]
Monday paper: Comparing soil biogeochemical processes in novel and natural boreal forest ecosystems
Quideau, S. A., Swallow, M. J. B., Prescott, C. E., Grayston, S. J., Oh, S.-W. 2013. Comparing soil biogeochemical processes in novel and natural boreal forest ecosystems. Biogeosciences, 10, 5651-5661. DOI: 10.5194/bg-10-5651-2013 Abstract Emulating the variability that exists in the natural landscape prior to disturbance should be a goal of soil reconstruction and land reclamation efforts following resource extraction. Long-term ecosystem sustainability within reclaimed landscapes …[Read More]

It needn’t be Hell with soil
This is one of the pictures the year has left. In it, two Muslim militiamen armed with machetes are registering a Christian in the Miskine neighborhood, in Bangui (Central African Republic), December 13, 2013. About 1,600 and 3,000 French soldiers already there of the African MISCA international mission were not able to stop violence and chaos. …[Read More]
Monday paper: A dual isotope approach to isolate soil carbon pools of different turnover times
Torn, M. S., Kleber, M., Zavaleta, E. S., Zhu, B., Field, C. B., Trumbore, S. E. 2013. A dual isotope approach to isolate soil carbon pools of different turnover times. Biogeosciences, 10, 8067-8081. DOI: 10.5194/bg-10-8067-2013. Abstract Soils are globally significant sources and sinks of atmospheric CO2. Increasing the resolution of soil carbon turnover estimates is …[Read More]
Monday paper: Combined use of stable isotopes and fallout radionuclides as soil erosion indicators in a forested mountain site, South Korea
Meusburger, K., Mabit, L., Park, J.-H., Sandor, T., Alewell, C. 2013. Combined use of stable isotopes and fallout radionuclides as soil erosion indicators in a forested mountain site, South Korea. Biogeosciences 10, 5627-5638. DOI: 10.5194/bg-10-5627-2013, 20133 Abstract The aim of this study is to assess and to validate the suitability of the stable nitrogen and carbon isotope signature as soil erosion …[Read More]
Cold soil in the groove
Often, soils from cold regions, such as Arctic soils, show polygonal forms in their surface. These polygons are formed because of the freeze-thaw cycle, characteristic of permafrost. What is permafrost? Permafrost is a subsurface soil layer which stays permanently frozen (below 0 oC) during long periods of time, usually more than two consecutive years. Most extensive …[Read More]
Monday paper: Modelling soil organic carbon stocks in global change scenarios: a CarboSOIL application
Muñoz-Rojas, M., Jordán, A., Zavala, L. M., González-Peñaloza, F. A., De la Rosa, D., Pino-Mejias, R., and Anaya-Romero, M. 2013.

Abstract Global climate change, as a consequence of the increasing levels of atmospheric CO2 concentration, may significantly affect …[Read More]
Monday paper: Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards
A. Novara, L. Gristina, F. Guaitoli, A. Santoro, A. Cerdà. 2013. Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards. Solid Earth, 4, 255-262, doi:10.5194/se-4-255-2013 Abstract When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil nitrates can pollute surface and subsurface waters. Strategies to …[Read More]
Soils at Imaggeo: soil erosion in olive groves
Artemi Cerdà, Spain Olive-cropped soils in Spain cover more than 2.4 million ha, 75% in southern Spain. Historically, high soil erosion rates have been determined in olive groves due to soil management, mostly. Due to Mediterranean climate conditions and low water inputs, traditional management is based on reduced tree density, canopy size control by pruning, and intensive …[Read More]
