Fuzzy Classification in the Determination of Input Application Zones Rev. Bras. Ciênc. Solo
Lima,Julião Soares de Souza; Costa,Felipe Pianna; Xavier,Alexandre Cândido; Silva,Samuel de Assis.
ABSTRACT Correctly interpreting soil fertility and its spatial distribution within an area helps to lessen losses and environmental effects associated with agriculture, to optimize fertilization and liming practices. This study is aimed at using concepts and methods from spatial and temporal analyses to soil fertility and to develop a fuzzy classification methodology in an effort to define input application zones in three conilon coffee harvests. An irregular network with georeferenced points was built in the central region of the farm. Soil samples were collected at 0.00-0.20 m depth within the projections of tree canopies. Geostatistical analysis was used to set up maps in which the variables were shown. In such maps, input and output fuzzy sets were...
