                         sector by the Sugarcane Research Center of Colombia Cenicaña has 
                         the objective of improve the crop yield in the country. Good 
                         fertilization rates can be related to good productivity by the 
                         crop, therefore, nutritional elements estimations, as nitrogen, 
                         phosphorus or potassium estimations, are needed in order to 
                         provide the appropriate nutritional rate to the sugarcane crop. 
                         The use of Remotely Piloted Aircraft Systems RPAS, together with 
                         multispectral cameras, has allowed the acquisition of high spatial 
                         resolution images and images with spectral information in and 
                         outside the visible spectrum, generating an alternative and 
                         nondestructive technological approach to estimate nutritional 
                         elements while monitoring sugarcane crops. The objective of this 
                         paper was to evaluate the relationship between five vegetation 
                         indices derived from a modified camera that allows spectral 
                         information in the red edge and ten nutritional elements 
                         (nitrogen, phosphorus, potassium, calcium, magnesium, iron, 
                         manganese, copper, zinc and boron) measured in the foliage of 18 
                         plots of a sugarcane crop experiment with the variety CC 93-4418. 
                         The best relationships were obtained between the vegetation 
                         indices and two of the primary macro-nutrients: phosphorus and 
                         potassium, one of the secondary macro-nutrients: magnesium and one 
                         of the micro-nutrients: zinc.",
