Características químicas de suelos forestales chilenos

Abstract: Chemical properties of 42 Chilean forest soil profiles, corresponding to 207 samples between 33° and 53° South latitude, are discussed. Water pH and pH-KCl in surface mineral horizons varied from 3.1 to 6.6 and from 3.2 to 5.9 respectively. The most acidic soils were located in the southern latitudes. Humus was accumulated on soil surface and decreased markedly with depth. C/N relationships indicated an increase of humus evolution with profile depth. Fulvic acid/humic acid relationships increased with depth. C… Show more

“…The normal trend is to find the higher content of nutrients in the A and AC horizons of the undisturbed forest (0-40 cm) that when removed after scarification leave a more limited soil. The pH is strongly acidic in most of the horizons, as expected in the forests of southern Chile (Sadzawka et al, 1995), without marked differences between situations. It must also be noted the high aluminum saturation, which may be due in part to leaching (especially calcium), because of the high rainfall in the area and the low organic matter content of the scarified soil.…”

“…Los suelos forestales, en general, son bastante ácidos; sin embargo, los niveles de acidez observados en Rucamanque se encuentran dentro de los rangos normales para suelos de bosques nativos de estas latitudes (Sadzawka et al 1995). Bürgmann (1998) informa que el pH de los suelos del Glomalina en bosque nativo sector fluctúa entre 4,9 y 5,0; mientras que Carrillo et al (1992) encontraron pH entre 5,1 y 5,8 en andisoles bajo formaciones boscosas caducifolias templadas de N. obliqua (Asociación Nothofago-Perseetum).…”

“…Otras publicaciones (INTA-ORSTON 1991, Thiers 1997) no son explícitos en la clasificación taxonómica del horizonte, por lo cual plantean la hipótesis que su origen es volcánico (depósito de cenizas), combinado con procesos de podzolización (eluviación). Con los datos analizados en este trabajo y otros (Sadzawka et al 1995, Arroyo et al 1996 7 , F. Colmet-Daage, recopilación inédi-ta de datos y W. Luzio comunicación personal) esta última hipótesis sería razonable. Frequency of the development depth of the soil in Río Bueno and Río Cóndor.…”

“…La existencia del horizonte E restringe el desarrollo de las raíces a mayor profundidad, posiblemente por su elevada acidez y sus altos niveles de aluminio. En todo caso, los niveles de acidez observados están dentro de los rangos normales para suelos bajo bosques nativos de estas latitudes australes (Sadzawka et al 1995).…”
