             abstract = "The use of remote sensing as a methodology for monitoring is 
                         favorable in the sugarcane crop, because of the efficiency of the 
                         methods that can be applied and the low cost. The objective of 
                         this work was to correlate NDVI (Normalized Difference Vegetation 
                         Index), NDWI (Normalized Difference Water Index) and EVI (Enhanced 
                         Vegetation Index) vegetation index with soil parameters in a 
                         sugarcane area. From the Landsat-8 images, the values of the three 
                         vegetation indices were calculated and extracted, after which it 
                         made a Pearson correlation with the parameters collected in the 
                         field. The values of the indices were 0.330-0.457 for NDVI, 
                         -0.099-0.034 for NDWI and -0.191-0.283 for EVI, it was noticed 
                         that the situation that the culture isnt favorable for its period 
                         (density of vegetation). The best correlation results were 0.142 
                         potassium with NDVI, water retained (0.112), particle density 
                         (0.112), total porosity (0.171) and resistance to penetration 
                         (0.267) with NDWI and the coarse sand (0.393), Total sand (0.317), 
                         macroporosity (0.25) and pH (0.162) with EVI. It was verified the 
                         importance of the monitoring of these parameters in the crop, as 
                         well as the need to deepen the analysis through spatial 
                         dependence, in order to verify the pattern of occurrence of the 
                         parameters.",
