Usle - rusle C factor estimation for eucalyptus plantations

Usle - rusle C factor estimation for eucalyptus plantations

In the last 5 years the area under forest in Uruguay has grown at a rate of 24.000 ha/yr through plantation of different species of Eucalyptus. This brought about concern for possible impacts on the environment and the natural resources. The objective of this study was to obtain local data of soil loss ratios (RPS) of soils under eucalyptus during installation and bare soil, to estimate the C factor of the Universal Soil Loss Equation (USLE) with the aim of guiding decisions making on use and management to reduce erosion. The submodel concerning the effect of use and management of the revised version of the model (RUSLE) was used with experimental measurements of the following variables as inputs: biomass in the upper 10 cm of soil, percentage of soil covered by vegetation, percentage of soil covered by residues, random roughness, and eight dripping of rain from the vegetation canopy. These determinations were made in different woodlots of two commercial plantations with contrasting technologies during 3 years. The main results are shown in two tables of RPS values recommended to be used for different productivity levels, plantation method and previous soil use.

En los últimos 5 años se ha producido un crecimiento del área forestada en Uruguay a un ritmo de 24.000 ha/año, con especies del género Eucaliptus. Esto ha provocado inquietudes por los efectos que pudieran producirse sobre el medio ambiente y los recursos naturales. El objetivo de este trabajo fue generar valores locales de relaciones de pérdida de suelo (RPS) entre suelos con eucaliptos durante su instalación y suelo desnudo , para estimar el Factor C de la Ecuación Universal de Pérdida de Suelo (USLE), con el objetivo de guiar la toma  de decisiones en cuanto a uso y manejo tendiente a reducir erosión. Para ellos se utilizó el submodelo referente al efecto del uso y manejo de la versión revisada del modelo (RUSLE) ingresándole determinaciones experimentales de las variables biomasa en los primeros 10 cm del suelo, porcentaje del suelo cubierto por residuos, porcentaje del suelo cubierto por vegetación, rugosidad al azar y altura de regoteo de la lluvia desde la parte aérea de la vegetación. Estas determinaciones se realizaron en distintos montes de dos plantaciones comerciales de tecnologías contrastantes durante 3 años. Los resultados concluyen en dos cuadros de valores de RPS que se recomiendan usar para distintos niveles de productividad, formas de plantación y uso previo del suelo.
