Soil properties related to water repellency in volcanic soils at Tenerife (Canary Islands, Spain): relationships with vegetation and soil parent material
نویسندگان
چکیده
Soil water repellency (SWR) was studied in 64 surface soil samples from Tenerife (Canary Islands, Spain), distributed over three different plant communities (natural and afforested Canarian pine forest, and high mountain legume scrub) and three types of soil parent materials (basaltic and salic rocks and basaltic tephra). Soils were studied for physicochemical properties (soil pH and salinity, nutrient contents, organic C and total N, particle size fractions and parameters related to andic soil properties), as well as for common SWR tests (Water Drop Penetration Time and Molarity of the Ethanol Droplet). The results suggest that SWR is more intense in silty-textured soils, with relatively high contents in organic C and nutrients, as well as in Al-humus complexes, under afforested pine forest. Soil parent material was shown to be less decisive in this sense.

Natural and Acquired Soil Quality along Environmental Gradients (tenerife, Canary Islands, Spain)
Abstract Tenerife Island, has a wide environmental diversity due to its altitude (3718m at its highest point) and to the climatic differences between its windward and leeward slopes. This work studies the changes in the natural soil quality along environmental gradients on the Tenerife Island and how this natural quality is modified by man’s effect on the ecosystem. For this purpose, a total of...

The stability over time of the organic C stocked in soils under undisturbed ecosystems is poorly studied, despite being suitable for detecting changes related to climate fluctuations and global warming. Volcanic soils often show high organic C contents due to the stabilization of organic matter by short-range ordered minerals or Al-humus complexes. We investigated the dynamics of different orga...

The island of Tenerife (Canary Islands, Spain), is showing possible signs of reawakening after its last basaltic strombolian eruption, dated 1909 at Chinyero. The main concern relates to the central active volcanic complex Teide – Pico Viejo, which poses serious hazards to the properties and population of the island of Tenerife (Canary Islands, Spain), and which has erupted several times during...
