| Abstract | Este trabalho teve por objetivos utilizar krigagem por indicação para espacializar propriedades de solos expressas por atributos numéricos, gerar uma representação acompanhada de medida espacial de incerteza e modelar a propagação de incerteza por procedimentos fuzzy de álgebra de mapas. Foram estudados os atributos: teores de potássio (K) e de alumínio (Al) trocáveis, saturação por bases (V), soma de bases (S), capacidade de troca catiônica (CTC) e teor de areia total (AT), extraídos de 222 perfis pedológicos e de 219 amostras extras, localizados no estado de Santa Catarina. Quando os atributos foram expressos em classes de fertilidade, a incerteza de Al, S e V aumentou e a de K e CTC diminuiu, considerando intervalos de confiança de 95 % de probabilidade. Constatou-se que um maior número de dados numéricos de K, S e V levou a uma maior incerteza na inferência espacial, enquanto o maior número de dados numéricos de AT e CTC diminuiu o grau de incerteza. A incerteza diminuiu quando diferentes representações numéricas foram integradas. The objectives of this study were to use kriging indicators to generate a representation of soil properties expressed by numeric attributes, to assess the uncertainty in estimates, and to model the uncertainty propagation generated by the fuzzy procedures of map algebra. The studied attributes were exchangeable potassium (K) and aluminum (Al) contents, sum of bases (SB), cationic exchange capacity (CEC), base saturation (V), and total sand content (TST), extracted from 222 pedologic profiles and 219 extra samples, located in Santa Catarina State, Brazil. When the attributes were expressed infertility classes, the uncertainty of Al, SB, and V increased while the uncertainty of K and CEC decreased, for intervals of confidence of 95% probability. A larger number of numeric data for K, SB, and V provided a larger uncertainty for space inference, while the uncertainty degree decreased for the largest number of numeric data of TS and CEC. There was a decrease of uncertainty when different numeric representations were integrated by fuzzy procedures of map algebra. |
