Tráfego do Forwarder promove compactação em solos coesos

Abstract

The use of heavy machinery in forest harvesting favors the increase of environmental impacts, mainly related to soil compaction, influencing the reduction of forest exploitation. Thus, we aimed to evaluate a compaction in cohesive soils caused by Forwarder traffic in eucalyptus harvest. The study was carried out in two forest harvesting areas of eucalyptus peoples located in Itanagra – Ba (area 1) and Entre Rios – BA (area 2). The statistical design used was randomized blocks in a 5x3 factorial scheme (past x ground depth), with 5 past conditions of the router (0, 1, 3, 5 and 7) measured at three different depths (0.0–0, 20 m, 0.20–0.40 m, 0.40–0.60 m) with 12 repetitions, six collected in the right-hand traffic line and six in the left-hand line). Ground penetration resistance (RSP) was analyzed to a depth of 0.60 m on the Forwarder traffic lines. areas 1 and 2 high values of soil resistance to penetration due to clay content. Limit the presence of fragments of the highest resistance values found in area 2. Increasing Forwarder traffic implies increased compaction to a depth of 0.60 m. All evaluated layers are compacted to areas as areas, but the largest compaction increments are layers in the 0.0–0.20 m depth layer.
