Conteúdo: |
O gerenciamento adequado de áreas agrícolas ou a modelagem de erosão de bacias são alguns dos desafios ambientais que requerem quantidades de dados, precisos e gerados tempo hábil para a pesquisa. Dos atributos do solo de interesse ambiental, o atributo argila é um dos primordiais, conquanto a mensuração desse é obtida convencionalmente por granulometria em laboratório, apresentando descompasso para o fornecimento dessa informação. Sendo assim, avaliaram-se os mapas preditos de argila realizado por sensores proximais portáteis (condutivímetro/susceptibilímetro e gamarradiômetro) e outro utilizando 21 derivadas do MDE (gerado por GPS geodésico), com resolução de 1 metro, em 3,4 ha de área de estudo em Seropédica - RJ. Os modelos de predição da argila apresentaram valores de R² 0.91 e 0.74, para derivadas de MDE e sensores proximais, respectivamente. Embora, o mapa que apresentou menores erros, mas não tão discrepantes, foi o baseado no modelo utilizando sensores proximais. |

The purpose of this study was to evaluate Cu and Zn migration and fractions in sandy soil of vineyards. In Urussanga (SC), Brazil, soil samples were collected from a 4-year-old and 15-yearold vineyard, and from a forested area. In the soils, the chemical characteristics of Cu and Zn were analyzed by the EDTA method, which determines the fraction available in soil; 3050B method of the USEPA for total concentrations, which represents the pseudosoil contents in the soil; and chemical fractionation, which estimates soluble fraction, exchangeable fraction, fraction associated with clay minerals, fraction associated with organic matter and residual fraction. The results show that there is accumulation of Cu and Zn in sandy soils cultivated with grapevines and with frequent fungicide applications. These higher levels were found in soils with longer cultivation time (15 years old), but were restricted to the superficial layers of the soil. Most of the Cu was extracted by EDTA method, and it may be considered as available to plants. The EDTA also extracted a small part of Zn. Most of the Cu in the vineyard soils can be characterized by low geochemical mobility, but in the uppermost soil layers of the oldest vineyard, there was an increase in Cu content associated with soil organic matter. Most of the Zn in the vineyard soil was associated with minerals, which indicates low mobility and also low potential for toxicity to plants and microorganisms. Key words: availability, chemical fractionation, toxicity, environmental contamination, Vitisvinifera.
