Resumo: | The nutrient cycling is influenced by the successional stage. However, there are differences in the pattern of this dynamic. The present study aimed to evaluate the chemical attributes of the topsoil and litterfall in two abandoned plantations of the eucalyptus Corymbia citriodora in different stages of Atlantic Rainforest succession (YP: Young plantation; MP: mature plantation) at the União Biological Reserve, RJ. We tested the hypothesis that there is an increase in the nutrient contents in the topsoil and litterfall, the amount of litterfall and nutrient input to the soil, as the process of forest succession advances. We sampled the topsoil (depth of 0-10 cm; dry season/2008, rainy season/2008, dry season/2009, rainy season/2010) and litterfall (0.49 m2 traps; 1.0 m above the forest floor; twice a month; 366 days) in five plots (5 m x 20 m) in the areas of PJ and PM. The topsoil in the PM area presented higher content of both total C and N, N + Al and Mn. On the other hand, the values of pH, C/N ratio and content of K, Fe and Zn were higher in the topsoil in the PJ area. No clear pattern was detected in terms of the P and Cu content in the topsoil. The annual litterfall was higher in the PM area, which presented higher content of total N and Mg, while higher C/N ratio and content of P and Ca occurred in the PJ area. We did not detected differences in terms of total C in litterfall. The input of C, N, P, K and Mg to the soil were higher by the litterfall in the area of PM, and there were no differences between PJ and MP in relation to the Ca input. We partly corroborated the tested hypothesis in relation to the nutrient content in topsoil, litter and nutrient input, although we completely corroborated the hypothesis in terms of litterfall. |

Contudo, existem divergências quanto ao padrão desta dinâmica. No presente estudo, objetivou-se avaliar os atributos químicos do solo superficial e da serapilheira produzida em dois plantios abandonados do eucalipto Corymbia citriodora em diferentes estágios de sucessão secundária de espécies nativas de Mata Atlântica (PJ: plantio jovem; PM: plantio maduro), na Reserva Biológica União, Rio de Janeiro. Testou-se a hipótese de que ocorre o incremento da concentração de nutrientes na camada superficial de solo e na serapilheira, da produção de serapilheira e do aporte de nutrientes para o solo via serapilheira, em função do avanço da sucessão. Em cinco parcelas (5 m x 20 m) em PJ e PM, foram realizadas amostragens da camada superficial do solo (0-10 cm; estações seca/2008, chuvosa/2008, seca/2009 e chuvosa/2010) e da serapilheira (coletores com 0,49 m2; 1,0 m acima do solo; coletas quinzenais; período amostral de 366 dias). A camada superficial do solo na área PM apresentou maiores concentrações de C e N totais, H+Al e Mn. Por outro lado, os valores de pH, razão C/N, concentrações de K, Fe e Zn foram maiores na camada de solo superficial na área PJ. Não se detectou padrão claro para as concentrações de P e Cu no solo. A produção anual de serapilheira foi maior na área PM, que apresentou maiores concentrações de N total e Mg, enquanto na área PJ foram verificadas maiores valores da razão C/N e concentrações de P e Ca. Não houve variação para C total na serapilheira. Os aportes de C, N, P, K e Mg foram maiores na serapilheira na área PM, e não houve diferenças entre as áreas PJ e PM para o aporte de Ca. A hipótese testada corroborou, em parte, a concentração de nutrientes na camada superficial do solo, na serapilheira e o aporte de nutrientes, e integralmente no que se refere à produção de serapilheira.Universidade Federal de Santa Maria2018-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3206610.5902/1980509832066Ciência Florestal; Vol. 28 No. 2 (2018); 674-686Ciência Florestal; v. 28 n. 2 (2018); 674-6861980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32066/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessCamara, RodrigoSilva, Vinicius DuncanDelaqua, Geovana Carla GirondiLisbôa, Cinthia PinheiroVillela, Dora Maria2018-06-29T11:07:47Zoai:ojs.pkp.sfu.ca:article/32066Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-06-29T11:07:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
