Resumo: | The planted forests using exotic trees are increasing areas and have replaced native vegetation in the southern Brazilian highlands, which can change the dynamics of soil nutrients. The objective was to evaluate the effects of the land use change on pH and total soil organic carbon (COT), Al3+, Ca2+, Mg2+ and K+ contents on a Humic Dystrudept under plantations established in native grassland area. The land uses evaluated were pinus established in 1963 (P) and eucalyptus planted in 1991 (E), comparatively to adjacent areas of native grassland (NP), natural regeneration since 1990 (NR), and native forest (NF). Soil samples were collected at 0-5, 5-10 and 10-20 cm depth, in eight replicates for each land use to calculate means and confidence intervals (95%). In general, NP and NF showed the highest values of TOC. “P” stand compared to NP had lower TOC, Ca and K in the 0-10 cm layer, indicating negative effects of forest plantations in comparison with natural grassland in relation to carbon and nutrient cycling. NR area showed similar values of those properties in relation to NP and NF areas. Long-term evaluations are important to verify influences of forest plantations on soil properties and identify the sustainability of these land use forms. |

Dessa maneira, o objetivo deste estudo foi avaliar os efeitos da mudança de uso da terra sobre pH e teores de carbono orgânico total (COT), Al3+, Ca2+, Mg2+ e K+ em Cambissolo Húmico, em plantios realizados em área de campo nativo. As áreas analisadas foram pinus plantado em 1963 (P) e eucalipto em 1991 (E), comparativamente a áreas adjacentes remanescentes: de campo nativo em regeneração natural a partir de 1990 (RN), mata nativa (MN) e campo nativo (CN). As amostras de solo foram coletadas nas profundidades de 0-5, 5-10 e 10-20 cm, em oito pontos para cada área avaliada, com cálculo de médias e intervalos de confiança (95%). Em geral, CN e MN apresentaram os maiores valores de COT. O plantio “P” apresentou em relação ao CN menores teores de COT, Ca e K na camada 0-10 cm, enquanto o plantio “E” apresentou menores teores de COT em relação ao CN, indicando efeitos negativos da floresta plantada em relação à vegetação natural campestre quanto à ciclagem de carbono e nutrientes. A área RN apresentou valores desses atributos similares aos do CN e MN. Avaliações em longo prazo são importantes para verificar influências do cultivo florestal sobre atributos do solo e identificar a sustentabilidade das formas de uso do solo.Universidade Federal de Santa Maria2020-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1890510.5902/1980509818905Ciência Florestal; Vol. 30 No. 2 (2020); 279-290Ciência Florestal; v. 30 n. 2 (2020); 279-2901980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/18905/18905Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessKlug, IzabelMafra, Álvaro LuizFriederichs, AugustoRech, CleberFert Neto, João2021-05-20T04:00:45Zoai:ojs.pkp.sfu.ca:article/18905Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:45Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
