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]

Cracked soils

Vertisols are dark clayey soils that show cracks at least during some part of the year. Normally, Vertisols are found in depressions or plain areas under subhumid or semiarid climate, with a wet and a dry season. Although climax vegetation is savanna, grassland or woodland, Vertisols are very fertile, so that agricultural use is very common. However, the process of swelling/shrinking makes Vertiso ...[Read More]

Wikipedia is evil

Yesterday, I had to write the exam questions for my students of Soil Science in the Faculty of Biology. As there are many more than 300, because of the facilities that my government gives to the fulfilment of the Bologna Process and the European Higher Education Area (ironic mode activated), I usually make multiple choice tests (if you do the same, have a look at this). However, I like to put some ...[Read More]

However, it is time consuming to measure and is, therefor ...[Read More]
