             abstract = "The use and analysis of remote sensing products, such as 
                         vegetation indices (NDVI, EVI), assist in crop yields forecast and 
                         could help to match soil fertility status and culture needs, 
                         avoiding unnecessary expenses. Remote sensing could revolutionize 
                         conventional agriculture by facilitating the management of 
                         soybean. This study aimed to evaluate the relationship between 
                         NDVI and EVI indices obtained from MODIS with soybean phenological 
                         cycle using a profile temporal spectrum, relating the spectral 
                         response with soil and plants attributes in four commercial plots 
                         in Campo Verde, MT. We used products from MODIS, MOD13Q1 and 
                         MYD13Q1 sensors. These sensors present NDVI and EVI indices as 
                         image compositions with spatial resolution of 250 meters, and the 
                         Pixel Reliability tool, that indicates how reliable each pixel is. 
                         We correlated the extracted NDVI and EVI indices with measured 
                         field data through Pearson correlation. EVI showed higher 
                         correlations and greater sensitivity to soybean phenological cycle 
                         than NDVI in a time spectrum profile. The phenological stage R5 
                         (grain filling) had high negative correlation with soil phosphorus 
                         (P) and high positive correlation with clay content in the four 
                         plots. Clay content also correlated with productivity in some 
                         plots. It was observed that EVI R5 phase was better correlated 
                         with final soybean yield.",
