Background and aims: The functioning of arid zone ecosystems depends on the fraction of precipitation that enters the soil and can be absorbed by vegetation. Vegetation affects infiltration by modifying droplet size, altering soil structure and changing microtopography. The objective of the work was to evaluate infiltration parameters in two soil-vegetation complexes in the central mount of San Juan.
M&M: Visual interpretation of satellite images and field work identified and characterized soil-vegetation complexes (SVCs). Bare soil and covered soil were the two surface conditions defined for each SVCs. A simple ring and variable load infiltrometer performed the infiltration tests. The samples taken from the soil determined texture, organic matter content, apparent density, available nitrogen, salinity, among others.
Results and Conclusions: Two SVCs were recognized: one dominated by Prosopis flexuosa and the other by Larrea divaricata. In the first complex, the soil presented a sandy clay loam texture, while in the second the texture was sandy loam. In both SVC, the mean infiltration speed (p=0.03), basic (p=0.02) and initial infiltration (p=0.02) were statistically different between bare soil and covered soil. In addition, the mean infiltration rate was 2.48 times higher in the complex dominated by carob trees compared to bare soil. These results suggest that the presence of vegetation favors the infiltration and entry of water into the soil. These data could be used as inputs for the elaboration or adjustment of hydrological models of the Monte. |

Introducción y objetivos: El funcionamiento de los ecosistemas de zonas áridas depende de la fracción de la precipitación que ingresa en el suelo y puede ser absorbida por la vegetación. La vegetación afecta la infiltración al modificar el tamaño de la gota; alterar la estructura del suelo y cambiar la microtopografia. El objetivo del trabajo fue evaluar parámetros de infiltración en dos complejos de suelo-vegetación en el Monte central de San Juan. M&M: Se identificaron y caracterizaron los complejos suelo-vegetación (CSV) mediante interpretación visual de imágenes satelitales y trabajo de campo. Para cada CVS, se definieron dos condiciones de superficie (suelo desnudo y suelo cubierto) y se realizaron ensayos de infiltración con un infiltrómetro de anillo simple y carga variable. Se tomaron muestras de suelo y se determinó textura, contenido de materia orgánica, densidad aparente, nitrógeno disponible, salinidad, entre otros. Resultados y Conclusiones: Se reconocieron dos CSV; uno dominado por algaborro (Prosopis flexuosa) y otro por jarilla (Larrea divaricata) En el primer complejo, el suelo presentó una textura franco-arcillo-arenoso, mientras que en el segundo la textura fue franco-arenoso. En ambos CSV, la velocidad media de infiltración (p=0.03), infiltración básica (p=0.02) e inicial fueron (p= 0.01) estadísticamente diferentes entre suelo desnudo y suelo cubierto. Además, la velocidad media de infiltración fue 2.48 veces mayor en el complejo dominado por algarrobo respecto de suelo desnudo. Estos resultados sugieren que la presencia de vegetación favorece la infiltración y el ingreso de agua al suelo. Esta información podría ser utilizada para la elaboración o ajuste de modelos hidrológicos del Monte.
