| ABSTRACT The present study aimed to evaluate the accumulation and distribution of Cu and Zn fractions in the profile of an Inceptisol by application of fungicides with a previous history of apple cultivation in southern Brazil. Stratified soil samples (0.0 – 0.025 m, 0.025 –0.050 m, 0.05 – 0.10 m, 0.10 – 0.15 m, 0.15 – 0.20 m and 0.20 – 0.40 m depth) were collected in two apple orchards (8 years old and 18 years old), and in a native pasture area adjacent to the orchards. The soil was subjected to analysis of physical and chemical properties and to chemical fractionation of Cu and Zn. The fractions of soluble, exchangeable, organic, residual and total Cu and Zn accumulated in the topsoil (0.0 – 0.025 m) of the orchards, being higher in the orchard... |

| ABSTRACT Phosphorus (P) applications at dosages higher than the necessary may cause P buildup in the soil labile fractions and, consequently, pollution of water sources. This study aimed to assess accumulation of P fractions as well as the parameters of adsorption isotherms in soil profiles having a history of application of phosphate fertilizers and cultivated with apple trees. Soil samples were collected from an area with no history of cultivation and 2 apple orchards cultivated for 8 (P8) and 18 (P18) years, in the city of Urubici, Santa Catarina, southern Brazil. Soil samples were air dried, sieved in a 2-mm mesh, and subjected to chemical analyses (P adsorption) besides P chemical fractionation. Applications of phosphate fertilizers to the orchards,... |

| A aplicação de fontes de nitrogênio (N) em pomar de macieira pode incrementar o teor do nutriente no solo ao longo do ciclo, afetar o estado nutricional e a produção, mas parte do N pode ser perdido por lixiviação. O trabalho objetivou avaliar o teor de N total em folhas, a produção e o fluxo de N no solo e na solução, em um pomar de macieira com a aplicação de distintas fontes de N, em um experimento em Urubici (SC). Plantas foram selecionadas, receberam a aplicação de ureia (U), ureia peletizada (UP) e cama sobreposta de suínos (CS); além de um tratamento sem adubação (SA). Nas safras 2011/2012 e 2012/2013 foram analisados teores de N em folhas completas e mensurados o crescimento das plantas e a produção de frutos. Foram coletadas amostras de solo e de... |
