Resumo: On commercial plantation of Eucalyptus saligna, belonging to Suzano Paper and Cellulose Co., two Oxisol (coarse and clayey textured) were selected. Both soils were submitted to mechanized harvesting, and coppice was 1 year old (clayey soil) and 2 years old (coarse soil), when soil tillage systems were performed: harrowing and subsoiling. Undisturbed soil samples were collected at 50 cm from tree lines and at three depths: 0 to 10, 10 to 20 and 20 to 30 cm to determine bulk density, and soil resistance to penetrometer were measured until 60 cm deep on the tree line and between lines. Plants had its DBH and total height measured before and after soil was tilled. Both soil tillage systems increased eucalyptus coppice growth, and a good correlation was obtained between soil resistance to penetrometer measured at the distance of 125 cm from the tree line and at 25 cm of soil depth ( r2 = 0,615 ) and plant height. On the coarse soil, harrowing decreased plant development, mostly due to increasing macroporosity.

Suzano Bahia Sul, foram selecionados dois solos: (textura argilosa e média) submetidos às operações mecanizadas no corte e/ou baldeio, com plantas em rebrota de um ano (solo argiloso) e dois anos (textura média), adotando-se dois sistemas de preparo de solo: gradagem e sulcagem, visando avaliar a produtividade da rebrota do eucalipto e as alterações da estrutura do solo. Com base na densidade foi avaliada a estrutura do solo, determinada com amostras indeformadas a 50 cm da linha de plantio nas profundidades de 0-10, 10-20 e 20-30 cm e resistência mecânica do solo, avaliada com penetrógrafo até 60 cm de profundidade, com pontos considerados na linha e entrelinha. Nas plantas foi determinado o incremento em altura e DAP (Diâmetro à Altura do Peito) antes e depois do revolvimento do solo. No solo argiloso os tratamentos com preparo mostraram maiores incrementos em altura e DAP, sendo que a resistência mecânica avaliada na área de sulcagem a 125 cm da linha aos 20 e 25 cm de profundidade mostrou boa correlação r2 = 0,583 e r2 = 0,615 respectivamente com o incremento em altura. No solo de textura média, a gradagem manifestou produtividade inferior aos outros dois tratamentos.Embrapa Florestas2003-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1610Pesquisa Florestal Brasileira; n. 47 (2003): jul./dez.; 83-98Pesquisa Florestal Brasileira; No. 47 (2003): jul./dez.; 83-981983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1610/641Cavichiolo, Sandra ReginaDedecek, Renato AntonioGava, José Luizinfo:eu-repo/semantics/openAccess2018-03-22T17:55:17Zoai:pfb.cnpf.embrapa.br/pfb:article/1610Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-03-22T17:55:17Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
