“…As base cations are very soluble, the main losses are associated with soil erosion and leaching processes. The cation exchangeable capacity (CEC) shows small variations over time, without significant differences, following closely the variations on soil organic matter, in agreement with other studies (e.g., Huseyin, 2006;Inbar et al, 2014), which refer changes in CEC and organic matter in the same sense. The variation of the exchangeable acidity values had similar behaviour to the exchangeable aluminum content and always decreased during the experimental period.…”

“…The response of the electrical conductivity to the passage of the fire resulted in a slight reduction, a fact that is generally not observed, since the presence of the ashes contributes to an increase of salts in solution (Huseyin, 2006). Overall, effects of fire on chemical soil properties were described by several authors (e.g., Úbeda and Outeiro, 2009;Fonseca et al, 2011;Inbar et al, 2014;Armas-Herrera et al, 2016), yet with trends in temporal changes that are not always similar to those found in this study, which might be due to a large set of local factors as post-fire rainfalls, fire severity and intensity, litter thickness and moisture content, not always comparable in the referred studies.…”

“…However, previous studies carried out in Mediterranean ecosystems highlight a wide variability fire effects on soil properties and hydrological processes (e.g., Certini, 2005;Bento-Gonçalves et al, 2012;Inbar et al, 2014;Alcañiz et al, 2016), contributing to soil degradation.…”

Fire severity varies widely among and within wildfires. The objective of this work was to test the effectiveness of granular polyacrylamide (PAM) to reduce erosion in a Calcic Regosol exposed to different fire conditions. Three treatments were selected representing disturbances that coexist after a wildfire: unburned, low-moderate severity direct fire, and prolonged heating under moderate temperature [heated (HT)]. Granular PAM was spread on the surface of disturbed samples at two rates: (i) 0 (control) and (ii) 50 kg ha À1 . Additional application rates of 25 and 100 kg ha À1 were tested in HT. Three 80-mm rainstorms were applied with an intensity of 47 mm h À1 , separated by drying periods. PAM reduced soil loss in all storms in unburned and direct fire, although runoff increased during the first storm due to increased runoff viscosity. In the highly stable HT, soil loss was reduced only with an application rate of 100 kg ha À1 and after a drying period. In many cases, granular PAM could be effective to reduce post-fire erosion. In soils with high structural stability, a PAM dose should be selected to find a right balance between its stabilising effect on soil structure and its effect increasing runoff during the first storm.

“…Los contenidos de nutrientes, microorganismos y materia orgánica resultan severamente alterados, siendo estas dos últimas las que poseen un mayor impacto a causa de la imposibilidad de restituir sus contenidos de forma efectiva con enmiendas agrícolas (Edivaldo et al, 2014). En este contexto, los minerales de arcilla a consecuencia del incremento de las temperaturas, sufren alteraciones y la pérdida total o parcial de su elevada superficie específica, lo que trae consigo una disminución en su reactividad superficial y consecuentemente variaciones en sus propiedades (Inbar et al, 2014).…”

RESUMENLa materia orgánica y la fracción coloidal son los principales componentes edafológicos que se ven afectados por la quema indiscriminada de los matorrales. En consecuencia, por acción de las altas temperaturas se produce un deterioro de la estructura, pérdida de la capacidad de intercambio catiónico (CIC) y disminución de la fertilidad de los suelos. Por otro lado, se ha planteado el uso de tratamiento térmico in situ como estrategia de cimentación de suelos arcillosos en la construcción de obras civiles. Sin embargo, el efecto de la temperatura sobre la fracción coloidal sólo se ha evaluado frente a propiedades mecánicas; pocos estudios en relación a propiedades de importancia agrícola como la CIC, la estructura y la susceptibilidad a la erosión han sido realizados. El objetivo del presente trabajo fue estudiar mediante dispersión dinámica de la luz (DLS) el efecto de la temperatura sobre la fracción coloidal de suelos agrícolas. Para ello se recolectaron y caracterizaron dos muestras de suelos procedentes de los departamentos de Córdoba y Valle del Cauca. La fracción coloidal fue extraída mediante una variante del método de Bouyoucos y sometida a diferentes tratamientos térmicos (desde 150 a 550 °C). Las muestras se caracterizaron por análisis elemental, FT-IR, DLS y se evaluó su CIC. Se concluyó que las propiedades de la fracción coloidal son fuertemente alteradas por efecto de la temperatura, además de evidenciarse una disminución de la CIC (desde 76 a 35 y desde 103 a 26 cmol (+) /kg de suelo), el incremento del tamaño de partícula (desde 639 ± 165 a 1250 ± 435 y 606 ± 102 a 1540 ± 320) para S-Córdoba y S-Valle, respectivamente así como la eliminación de la materia orgánica.
