This work consists in presenting and discussing a methodology of interpretation of the temporal evolution of the productivity of agricultural cultures, whose harvests were realized by machines equipped with income and geopositioning sensors. From three distinct scenes, the evolution of the productivity of a soy farming was studied, considering three agricultural harvests, 2000/2001, 2002/2003 and 2003/2004 This study made possible to calculate the dimensions and to define the possibilities and limitations that are find in each scene, as well as concluding that the methodology presented for study of temporal dynamics, makes possible the georreferenced spacialization of the variability of the productivity difference between two successive harvests
