Singularities of geotechnical properties of complex soils in seismic regions
(ASCE-AMER SOC CIVIL ENGINEERS, 2008-07)
Volcanic activity results in a wide range of soil types with very unusual characteristics, the most remarkable of which are
volcanic ash clays containing the clay minerals allophane and imogolite. In addition to these ...
Effect of seaweed on phosphorus available of a soil derived from volcanic ash.
(American Society of Agronomy, 1971)
A volcanic ash-derived soil was incubated uo to 93 days with different amounts of seaweed. P was then extracted using an anion exchange resin method, and it was found that extractable P increased with increasing amounts ...
Impact of land use changes on the hydrological properties of volcanic ash soils in South Ecuador
(2002-06)
The effect of land use on the water retention capacity of Umbric Andosols in south Ecuador was studied. The objective was to acquire a better insight into the hydrological processes of the ecosystem and the role of the ...
Changes in soil organic matter associated with afforestation affect erosion processes: The case of erodible volcanic soils from Patagonia
(Elsevier Science, 2021-12)
Large areas of the Patagonian Andean Region with high potential for planting fast-growing exotic conifers, based on the volcanic nature of its soils, are affected by erosion processes. This study aimed to analyse the effects ...
Relative mobility of atrazine, 2,4-d and dicamba in volcanic soils of south-central chile
(LIPPINCOTT WILLIAMS & WILKINS, 2002)
Herbicide mobility has been studied extensively in nonvolcanic soils but not in the volcanic soils that are important to the agricultural systems of many regions, including Pacific-Rim countries. Volcanic soils have unique ...
Use of statistical methods for determining homogeneous layers of volcanic soils at a site in the slopes of Irazu volcano, Cartago, Costa RicaUso de métodos estadísticos para la determinación de capas homogéneas de suelos volcánicos en un sitio en las laderas del volcán Irazú, Costa Rica
(Universidad de Costa Rica, 2011)
INFLUENCE OF PARTICLE SIZE ON 31P-NMR ANALYSIS OF EXTRACTS FROM VOLCANIC ASH-DERIVED SOILS IN CHILE
(Sociedad Chilena de Química, 2004)
Soil erodibility and quality of volcanic soils as affected by pine plantations in degraded rangelands of NW Patagonia
(Springer, 2016-05)
NW Patagonia in Argentina has high potential for planting fast-growing exotic conifers, supported by its volcanic soils. Nonetheless, many aspects related to the effects of pine plantations on soil are still unknown. We ...
Sorption-desorption behavior of pesticides and their degradation products in volcanic and nonvolcanic soils: interpretation of interactions through two-way principal component analysis
(Springer, 2015)
Sorption-desorption behavior of six pesticides and
some degradation products was assessed on seven agricultural
volcanic and nonvolcanic soils belonging to Andisol, Ultisol,
Mollisol, and Alfisol orders. The global ...
