%X Seeking the improvement of crop productivity, radiometric models and vegetation indexes derived from image data, obtained by remote sensing, has been used for control and continuous monitoring of agricultural areas. From empiric models, it is possible to estimate the nutrients concentration and health parameters of plants infected by pathogens. Regarding this statement, the goal of this study was to evaluate the potential of empiric models to estimate the nutrients concentration in coffee culture infected by nematodes. The empiric models were generated using original bands and vegetation indexes derived from a RapidEye scene. In this approach, it was possible to estimate the concentration of potassium (K) and calcium (Ca) from empiric models, derived from vegetation index SR (simple reason), with a RMSE of 14.7% and 7.5%, respectively. With a model derived from the near-infrared band was possible to estimate the concentration of boron (B) with a RMSE of 13.3%.
