Lógica fuzzy no mapeamento de variáveis indicadoras de fertilidade do solo

Abstract

The objective of this experiment was to use fuzzy logic to map the sum of bases (SB), cation exchange capacity (CTC) and base saturation (V%) in an area with arabica coffee variety Catucai, considering the spatial variability, The samples of soil were held in a loop with 50 sampling points in the projection of the crown of the plants. The data were subjected to a descriptive analysis and exploratory. We used a classification system in the integration of fuzzy values of attributes. Then proceeded a geostatistic analysis to quantify the degree of dependence of the possibilities of spatial attributes. Based on the attributes evaluated, the area has low possibility of development and yield of crops, since these attributes showed a low possibility of availability.
