Resumo: | In coffee culture, the inadequate control of invasive plants can degrade the soil used then managements practices to contribute to the improvement of quality physical, chemical and biological of the soil. Should be used the aim of this work were evaluated the influence of various weed control methods on some chemical properties of a Red-Yellow Latosol (RYL) cultivated with coffee. The experimental design was randomized block with strip plots, making a 9x2 factorial, nine control methods and two layers (0-15 and 15-30 cm) and three replications. The control methods evaluated were: maintenance of soil cover with forrage peanut (Arachis pintoi L.) and Signal grass (Brachiaria decumbens), use of disk harrow, mower, agricultural brush, manual hoe, post-emergency herbicide, pre-emergence herbicide and no weeding treatment. The following chemical analyzes were performed: pH, exchangeable cations of sorption complex, sum of bases, base saturation, aluminum saturation, effective cation exchange capacity, potential cation exchange capacity, soil organic matter, total phosphorus and remanescent phosphorus. Among the weed control methods studied, the use of mower provided the best soil chemical characteristics at the two layers evaluated. The pre-emergence herbicide remained the surface of the soil devoid cover, wich negatively influenced the soil chemical attributes, by increasing the acidity and reduced cations of the sorption complex. The Signal grass showed higher efficiency than the forrage peanut in the management of alkaline front, although the latter was more efficient in phosphorus cycling. |

Objetivou-se, neste trabalho, avaliar a influência de diferentes métodos de controle de plantas invasoras em alguns atributos químicos de um Latossolo Vermelho-Amarelo (LVA) cultivado com café. O delineamento experimental adotado foi o de blocos casualizados em esquema de parcelas subdivididas, perfazendo um fatorial 9x2, sendo nove métodos de controle e duas camadas (0-15 e 15-30 cm) com três repetições. Os métodos de controle de plantas invasoras avaliados foram: manutenção da cobertura do solo com amendoim-forrageiro (Arachis pintoi L.) e capim-braquiária (Brachiaria decumbens), utilização de grade, roçadora, trincha, capina manual, herbicida de pós-emergência, herbicida de pré-emergência e tratamento sem capina. As seguintes análises químicas foram realizadas: pH em água, cátions trocáveis do complexo sortivo (Ca, Mg, K e Al), soma de bases (SB), saturação por bases (V), saturação por alumínio (m), capacidade de troca de cátions efetiva (t), capacidade de troca de cátions potencial (T), matéria orgânica do solo (MOS), fósforo total (P) e fósforo remanescente (Prem). Dentre os métodos de controle das plantas invasoras estudados, a utilização da roçadora propiciou as melhores condições químicas do solo, tanto da camada superficial como da subsuperficial. A utilização de herbicida de pré-emergência, que mantém a superfície do solo desprovida de cobertura vegetal, influenciou negativamente os atributos químicos do solo, pelo aumento da acidez e a redução dos cátions do complexo sortivo. O capim-braquiária apresentou maior eficiência que o amendoim-forrageiro no manejo da frente alcalina, embora esse último tenha sido mais eficiente na ciclagem do fósforo.Editora UFLA2015-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/zipapplication/zipapplication/ziphttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/788Coffee Science - ISSN 1984-3909; Vol. 10 No. 2 (2015); 138 - 148Coffee Science; Vol. 10 Núm. 2 (2015); 138 - 148Coffee Science; v. 10 n. 2 (2015); 138 - 1481984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/788/pdf_138https://coffeescience.ufla.br/index.php/Coffeescience/article/view/788/1379https://coffeescience.ufla.br/index.php/Coffeescience/article/view/788/1380https://coffeescience.ufla.br/index.php/Coffeescience/article/view/788/1381Copyright (c) 2015 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSiqueira, Raphael Henrique da SilvaFerreira, Mozart MartinsAlcântara, Elifas Nunes deSilva, Raphael Comanducci2015-06-02T14:28:49Zoai:coffeescience.ufla.br:article/788Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:50.140503Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
