Densidade ótima de estradas para povoamentos de Teca (Tectona grandis L.f.) no estado de Mato Grosso

Abstract

This study aimed to estimate the density (DOE), as well as determine the optimal spacing of roads (EOE) and the average distance extraction (DME) for stands of Tectona grandis L.f. the state of Mato Grosso, based on the costs of road use and forest logging, adapted by Kato (1966). Data were collected in Campina Farm, located in the district of Pirizal, city of Our Lady of Deliverance in geographic coordinates 16 ° 12 '03 "south latitude and 56 ° 22' 44" west longitude. We used a 4x4 tractor, agricultural extraction claw adapted for attachment to the drag of logs. The operation of extraction of timber determined the scaling of the density of roads (DOE) as a function of the characteristics and peculiarities and performance of the equipment used, topographical conditions, the productivity of crops, aiming at better economic alternatives. The estimation of optimum density of roads to the plantations of Meadow Farm was 44 meters / ha considering the average yield of 120 m³ / ha of plantations at nine years of age with optimal spacing of roads (EOE) and 227 meters average distance of extraction (DME) to 75 meters.
