The objective of this study was to evaluate the development and productivity of conventional farming system in maize and function of the spatial variability in precision agriculture of soil attributes as: NPK, characterized by the generation of isofertilidade maps and productivity. The experiment was conducted in an experimental area of the Federal Institute of Santa Catarina Campus South River, containing 10 plots of 256 m2 is divided into five precision farming plots and 5 plots the conventional system, by collecting soil samples and georeferencing points for preparation of maps using the program for the GS + 'mapping. The average values of productivity showed no significant differences between the compared systems, and there was variability in soil properties between the evaluated areas of the experiment. The analysis carried out through thematic maps allowed the observation that the amounts of N, P and K were different in precision agriculture system with a spatial variability of soil attributes of the great among the very precision farming plots, as in the conventional system does not variability was seen using average values of the soil sample.
