Resumo: This study aimed to determine levels of pressure and compaction induced by forest harvesting operations in a Red Latosol (LV) under planted eucalyptus. Undisturbed soil samples were collected from layers 0-3 and 15-18 cm and then used in a uniaxial compression test. Sampling was done before and after harvesting operations. Equipment being evaluated included: harvester, feller buncher, forwarder, self-loading adapted tractor, standard truck, wide-tire truck and grapple saw. Average pressures induced by the grapple saw were 320 kPa and 272 kPa, causing compaction in 80% and 20% of samples respectively from layers 0-3 cm and 15-18 cm, which indicates substantial degradation of soil structure in areas where timber is processed. In layer 0-3 cm, average pressures induced by the harvester and by the feller buncher were 240 kPa and 263 kPa respectively, while in layer 15-18 cm pressures were 234 kPa and 239 kPa respectively. The feller buncher caused higher soil compaction than the harvester in layer 0-3 cm, yet in layer 15-18 cm they had similar behavior. All timber forwarding equipment led to soil compaction. The wide-tire truck was the forwarding implement promoting the highest rate of compaction, in both residue conditions. Traffic intensity 7 promoted the highest rate of soil compaction.

Amostras indeformadas de solo foram coletadas nas camadas de 0-3 e 15-18 cm e usadas no ensaio de compressão uniaxial. A amostragem foi obtida antes e depois das operações de colheita. As máquinas avaliadas foram: Harvester, Feller Buncher, Forwarder, Autocarregável, Caminhão normal e de pneus largos e Garra Traçadora. As pressões médias induzidas pela Garra Traçadora foram iguais a 320 kPa e 272 kPa e promovendo compactação em 80% e 20% das amostras coletadas nas camadas de 0-3 cm e 15-18 cm, respectivamente, indicando grande degradação da estrutura do solo nas áreas de processamento da madeira. Na camada de 0-3 cm as pressões médias induzidas pelo Harvester e pelo Feller Buncher foram iguais a 240 kPa e 263 kPa, respectivamente e na camada de 15-18 cm foram iguais a 234 kPa e 239 kPa, respectivamente. O Feller Buncher promoveu maior compactação do que o Harvester na camada de 0-3 cm e na camada de 15-18 cm tiveram comportamento iguais. Todas as máquinas de baldeio promoveram compactação do solo. O Caminhão de pneus largos foi a máquina de baldeio que promoveu maior compactação do solo, nas duas condições de resíduo. A intensidade de tráfego igual a 7 foi a que promoveu maior compactação do solo.Universidade Federal de Lavras (UFLA)2016-04-052017-08-01T20:15:53Z2017-08-01T20:15:53Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfMARTINS, P.
