Resumo: In order to evaluate the effect of soil chemical and physical attributes on the productivity of 20 year-old Pinus taeda stands planted on different soil types and with different growth rates, four sites were selected based on previous inventory, in two municipalities in the State of Paraná. Experimental plots were established on these areas where dominant trees were selected. Data on DBH and height were recorded and stem cross section disks at different heights were collected. Also, soil samples at different depths were collected. Growth variables and tree volumes were analyzed and correlations with soil chemical and physical traits were estimated. The results showed that wood production was influenced mainly by soil physical traits. Of special importance was the amount of moisture available in the soil and the resistance to root penetration. On poor sites, productivity can beincreased by adopting some silvicultural measures such as pruning, thinning, fertilization and soil tillage.

Nestes sítios foram demarcadas parcelas experimentais, selecionadas árvores representativas do extrato dominante, coletados dados dendrométricos de altura e diâmetro, discos do lenho de diferentes alturas do tronco e amostras de solo em diferentes profundidades. Os parâmetros de crescimento e volume das árvores foram analisados e correlacionados com as propriedades físicas e químicas do solo. Os resultados obtidos mostram que a produtividade de madeira é influenciadapelas propriedades, principalmente físicas, do solo, em especial pela quantidade de água disponível e pela resistência à penetração das raízes. Mostram ainda, para sítios de menor crescimento das árvores, que a produtividade pode ser aumentadacom adoção de práticas silviculturais de poda e desbaste, adição de fertilizantes e descompactação do solo.Embrapa Florestas2011-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/203Pesquisa Florestal Brasileira; n. 53 (2006): jul./dez.
