Rendimientos operativos y costos de poda en plantaciones de Prosopis alba

Abstract

La poda forestal es una práctica necesaria para obtener una madera de calidad, libre de nudos y de mayor valor en el mercado. La misma requiere llevarse a cabo en varias etapas utilizando técnicas y herramientas adecuadas. La provincia de Santiago del Estero cuenta con casi 3.000 ha forestadas con algarrobo blanco (Prosopis alba), en la cual la mayoría carece de manejo silvícola. El objetivo de este trabajo es evaluar rendimientos operativos y costos de poda en plantaciones forestales de diferentes edades. La muestra estuvo conformada por 3 productores con parcelas ubicadas en los departamentos Robles y Loreto de la provincia de Santiago del Estero. El trabajo de campo permitió registrar los tiempos operativos de prácticas de poda con diferentes herramientas, como así también estimar los costos. El estudio demuestra que la 1a poda de formación demanda 0,32 min.árbol-1, la 2a poda de conducción requiere 0,81 min.árbol-1y la 3a poda 1,21 min.árbol-1. Asimismo, los rendimientos de poda por hombre resultaron en: 1,25 ha. jornal-1 para la 1.a poda; 0,66 ha. jornal-1 para la 2a poda y 0,25 ha. jornal-1 para la 3a poda. Se concluye que la especie Algarrobo blanco (Prosopis alba) requiere de una silvicultura de formación en tiempo y forma para garantizar una buena calidad de madera y reducir costos de ejecución.

Forest pruning is a practice necessary to obtain wood of quality, free of knots and of greater value in the market. It should be carried out in several stages using appropriate techniques and tools. The province of Santiago del Estero has almost 3.000 hectares planted with algarrobo blanco (Prosopis alba), most of which lack forestry management. The objective of this work is to evaluate the operating yields and pruning costs in forest plantations of different ages. The sample comprised 3 producers with plots located in the Robles and Loreto Departments of the province of Santiago del Estero. The field work allowed to record the operative times of the pruning practices with different tools, as well as to estimate the costs. The study shows that the first formation pruning requires 0.32 min. tree-1 , the second conduction pruning requires 0.81 min. tree-1 and the third pruning 1.21 min.tree- 1 . Likewise, pruning yields per man were: 1.25 ha. journal-1 for the first pruning; 0.66 ha. journal-1 for the second pruning, and 0.25 ha. journal-1 for the 3rd pruning.It is concluded that the species Algarrobo blanco (Prosopis alba) requires timely forestry training to guarantee a good quality of wood and reduce execution costs.
