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 permafrost areas can be found ...[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 reduce the nitrat ...[Read More]

Old and new composite pictures of San Francisco highlighting the impact of the 1906 earthquake

Old and new composite pictures of San Francisco highlighting the impact of the 1906 earthquake How would San Francisco look like if a similar 1906 earthquake had to strike again? Despite the many predictions and models, this is a good hint to help our imagination.

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 weed control. Weed contr ...[Read More]
