Efecto de la densidad de las forestaciones y la intensidad de cosecha em raleos mecanizados con harvester

Abstract: El objetivo de este estudio fue evaluar cómo la densidad de la forestación y la intensidad de los raleos afectan a la cosecha con harvester. Fueron evaluados siete harvesters diferentes, en nueve situaciones de segundo raleo de pino del noreste argentino. Los estudios de tiempos comprendieron el establecimiento de parcelas y la filmación de las operaciones. La densidad media de los rodales fue de 656 árboles.ha-1 , con un volumen medio de 0,53 m 3. El raleo extrajo en promedio el 45% de los árboles. Fueron aju… Show more

“…The average size of the extracted trees does not exceed 0.4 m³, and the volume of wood harvested is around 100-200 m³ ha -1 . Up to three assortments are bucked (two sawlogs and one pulpwood) and the share of pulpwood logs is more than 40% (Hildt et al 2019). The margins of the harvesting contractors depend on a constant increase in productivity and a decrease in production costs (Mac Donagh et al 2017).…”
