Resumo: The presence of weeds in apple orchards affects the dynamics of nutrients in the soil, including phosphorus (P). The objective of this study was to evaluate changes in distribution of P fractions in the soil of an apple orchard under different weed managements. The experiment was conducted in an apple orchard in the municipality of Urubici, Santa Catarina, Brazil. The following treatments were implemented in 2011: no weed management (NWM), desiccation of weeds in the apple-tree row (DR), and hoeing of weeds in the apple-tree row (HR). Soil samples of the 0-2.5, 2.5-5, 5-10, 10-15 and 15-20 cm layers were collected in the apple-tree rows at 24 months after the implementation of the experiment. The samples were subjected to chemical fractionation of P, obtaining the following fractions: PiAER, PiNaHCO3, PoNaHCO3, PiNaOH, PoNaOH, PiHCl, PiNaOH05, PoNaOH05, and Presidual. The presence of weeds increased the contents of the following soil P fractions in the surface layers: PiAER, PiNaHCO3, and PoNaHCO3, which are bioavailable to plants. A higher proportion of organic forms of P in the soil was found when the weeds were hoed; these fractions can be mineralized and used for nutrition of apple trees when labile P forms are exhausted.

El estudio tuvo como objetivo evaluar cómo diferentes manejos vegetales espontáneos en manzanos modifican la distribución de fracciones de fósforo en el suelo. El experimento se realizó en un huerto de manzanos del municipio de Urubici, Santa Catarina. En 2011 se implementaron tratamientos: sin manejo espontáneo de plantas (SM), desecación espontánea de plantas en la línea de plantación (DL) y siega de plantas espontáneas en la línea de plantación (RL). Luego de 24 meses de implantación del experimento, se recolectaron muestras de suelo en la línea de plantación de los manzanos en las capas de 0-2.5, 2.5-5, 5-10, 10-15 y 15-20 cm, y si el fraccionamiento químico de P, obteniendo las siguientes fracciones: PiAER, PiNaHCO3, PoNaHCO3, PiNaOH, PoNaOH, PiHCl, PiNaOH05, PoNaOH05 y Presidential. La presencia de plantas espontáneas favoreció el aumento del contenido de P en el suelo en las capas superficiales en las fracciones PiAER, PiNaHCO3 e PoNaHCO3 biodisponible para las plantas. Cuando se despejaron las plantas espontáneas, hubo una mayor proporción de formas orgánicas de P en el suelo, que se pueden mineralizar y usar en la nutrición de las manzanas cuando se agotan las formas lábiles de P.A presença de vegetação espontânea nos pomares de macieira afeta a dinâmica dos nutrientes no solo, entre eles o fósforo (P). O estudo objetivou avaliar como diferentes manejos de plantas espontâneas em pomares de macieira modificam a distribuição de frações de fósforo no solo. O experimento foi conduzido em um pomar de macieira no município de Urubici, Santa Catarina. Em 2011 foram implantados os tratamentos: sem manejo das plantas espontâneas (SM), dessecamento das plantas espontâneas na linha de plantio (DL) e roçada das plantas espontâneas na linha de plantio (RL). Após 24 meses da implantação do experimento, foram coletadas amostras de solo na linha de plantio das macieiras nas camadas de 0-2,5, 2,5-5, 5-10, 10-15 e 15-20 cm, e realizou-se o fracionamento químico de P, obtendo-se as seguintes frações: PiAER, PiNaHCO3, PoNaHCO3, PiNaOH, PoNaOH, PiHCl, PiNaOH05, PoNaOH05 e Presidual. A presença de plantas espontâneas favoreceu o aumento dos teores de P no solo nas camadas superficiais nas frações PiAER, PiNaHCO3, e PoNaHCO3 biodisponíveis às plantas. Quando as plantas espontâneas foram roçadas, houve maior proporção de formas orgânicas de P no solo, as quais podem ser mineralizadas e utilizadas na nutrição da macieira quando há depleção das formas de P lábeis.Research, Society and Development2020-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/876710.33448/rsd-v9i10.8767Research, Society and Development; Vol. 9 No. 10; e3449108767Research, Society and Development; Vol. 9 Núm. 10; e3449108767Research, Society and Development; v. 9 n. 10; e34491087672525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8767/7675Copyright (c) 2020 Andria Paula Lima; Cledimar Rogério Lourenzi; Jucinei José Comin; Arcângelo Loss; Gustavo Brunetto; Monique Souza; Bárbara Santos Ventura; Talita Trapp; Guilherme Wilbert Ferreirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLima, Andria Paula Lourenzi, Cledimar RogérioComin, Jucinei JoséLoss, ArcângeloBrunetto, GustavoSouza, Monique Ventura, Bárbara SantosTrapp, TalitaFerreira, Guilherme Wilbert2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8767Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:10.199956Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
