Resumo: | Black wattles can grow on several environmental conditions being a fast growing and short life pioneer specie. This work was established on Acacia mearnsii De Wild commercial plantations, belonging to TANAGRO Co., in Piratini, Rio Grande do Sul, Brazil, growing on different soil types, with plants from the same origin. In each of the five-soil type, a treatment to evaluate black wattle growth in DBH and height, and above ground biomass was considered. Soils had their surface horizons characterized morphological, chemical and physically, and nutritional status were measured in every plant compartment, tannin yield in plant bark, amount of lignin and total extractives were determined in commercial stem wood. Neossolo Litólico eutrófico (Entisol) showed the greatest commercial stem volumes and Neossolo Litólico álico (Entisol) was the least productive, especially due to soil fertility differences, mainly P level, base saturation and aluminum saturation. The amount of macronutrients returned, keeping harvesting residues (branches and crown) on soil surface, was greater than the amount exported in commercial stem and bark, attesting its efficiency on soil reclaiming, if the residues are not burned. In most productive soils in volume of commercial stems, the amount of calcium and magnesium exported was greater than the amount returned to soil. The amount of tannin in black wattle bark was greater in plants growing in adverse soil conditions (shallow and stony soils). |

Este trabalho foi realizado em povoamentos comerciais puros de acácia-negra de propriedade da TANAGRO S.A., no município de Piratini, RS, em cinco classes de solos, com plantas de mesma procedência, constituindo cada qual um tratamento. Em cada solo, foram avaliados o crescimento em DAP, altura e produção de biomassa aérea. Os solos foram caracterizados química, física e morfologicamente em seus horizontes superficiais. Nas plantas, foram determinado o estado nutricional dos diferentes compartimentos, o teor de tanino na casca e o teor de lignina e extrativos totais no tronco. O Neossolo Litólico eutrófico produziu o maior volume de troncos comerciais, enquanto o Neossolo Litólico álico foi o menos produtivo, mostrando a grande importância da fertilidade do solo na produtividade da acácia negra, sobretudo, o teor de P e as saturações por bases e por alumínio trocável. Se os resíduos não forem queimados, a quantidade de macronutrientes devolvida ao solo (por galhos, flor, folhas e vagens) é maior que a quantidade de macronutrientes exportada, com a retirada apenas do tronco comercial e casca, nos solos menos produtivos, confirmando que se trata de espécie recuperadora de solo. Nos solos com maior volume de troncos comerciais produzidos, a quantidade de cálcio e magnésio exportada foi maior do que a devolvida ao solo pelos resíduos da colheita. A concentração de tanino na casca da acácia-negra foi maior em condições adversas de solo, mas a maior produção de casca em solos melhores compensa esse fato.Universidade Federal de Santa Maria2007-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/194510.5902/198050981945Ciência Florestal; Vol. 17 No. 2 (2007); 137-144Ciência Florestal; v. 17 n. 2 (2007); 137-1441980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1945/1187Rachwal, Marcos Fernando GluckDedecek, Renato AntonioCurcio, Gustavo RibasSimon, Augusto A.info:eu-repo/semantics/openAccess2017-05-12T17:36:29Zoai:ojs.pkp.sfu.ca:article/1945Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-12T17:36:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
