Resumo: http://dx.doi.org/10.5902/1980509816607The pursuit of sustainable systems of soil management has led researchers to develop new techniques of cultivation. Among them, studies with forest species able to fix atmospheric N2 and increase C and N stocks in labile and stable soil organic matter (SOM) stand out in Brazil. The study aimed to evaluate changes in stocks of C and N in fractions of humic substances, light fraction of SOM and microbial biomass in soils of Eucalypt urograndis short rotation, long rotation plantations and stands of the Acacia mangium which succeeded eucalyptus short rotation monoculture, with reference to the soil of native forest (Atlantic Forest) adjacent. It was obtained the total organic carbon (TOC) and total nitrogen (TN) stocks, C and N stocks in the fractions of humic substances (fulvic acid fraction-AF, humic acid fraction-HA and humin fraction-H), C and N in light fraction of SOM (C-LOM and N-LOM) and C and N microbial biomass (C-MB and N-MB). The results indicated that the eucalyptus cultivation of short rotation reduced total organic carbon stocks, total nitrogen, C and N in the humic substances, and N storage in the microbial biomass compared to Acacia mangium soil. The cultivation of Acacia mangium and the increase of the eucalyptus rotation time have increased stocks of C and N of the labile (C-LOM, N-LOM and C-MB) and stable fractions (C and N in humic substances) indicating a significant recovery of their stocks to levels approaching those original (native), and higher than stocks obtained in the soil of eucalyptus short rotation.

Dentre elas, destacam-se no Brasil estudos realizados com espécies florestais capazes de fixar N2 atmosférico e aumentar o estoque de C e N em frações lábeis e estáveis da matéria orgânica do solo (MOS). O presente estudo teve por objetivo avaliar as alterações nos estoques de C e N em frações das substâncias húmicas, da fração leve da MOS e da matéria microbiana em solos cultivados com Eucalyptus urograndis em rotação curta, eucalipto em rotação longa e povoamentos de Acacia mangium que sucederam plantios de eucalipto em rotação curta, tendo como referência o solo de floresta nativa (Mata Atlântica) adjacente. Foram quantificados os estoques de C orgânico total e N total (COT e NT), nas frações das substâncias húmicas (fração ácido fúlvico-AF, fração ácido húmico-AH e fração humina-H), C e N da fração leve da MOS (C-MOL e N-MOL) e estoque de C e N da matéria microbiana (C-BM e N-BM). Os resultados indicaram que o cultivo do eucalipto em rotação curta apresentou menores estoques de COT e NT, nas frações das substâncias húmicas e, de N na matéria microbiana em comparação ao solo sob rotação com Acacia mangium. O cultivo de Acacia mangium e o aumento do tempo da rotação do eucalipto incrementaram os estoques de C e N da maioria das frações lábeis (C-MOL, N-MOL e C-BM) e estáveis (C e N nas substâncias húmicas). Indicando tendência de recuperação dos seus estoques para valores próximos daqueles originais (mata nativa), sendo superiores aos estoques obtidos na área de eucalipto em rotação curta.Universidade Federal de Santa Maria2014-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1660710.5902/1980509816607Ciência Florestal; Vol. 24 No. 4 (2014); 935-946Ciência Florestal; v. 24 n. 4 (2014); 935-9461980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/16607/pdfPegoraro, Rodiney FaccoSilva, Ivo Ribeiro daNovais, Roberto Ferreira deBarros, Nairam Felix deCantatutti, Reinaldo BertolaFonseca, Sebastiãoinfo:eu-repo/semantics/openAccess2017-04-12T13:34:29Zoai:ojs.pkp.sfu.ca:article/16607Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-12T13:34:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
