Abstract: The mathematical model associated with the knowledge of the soil variability properties and mapping the relief forms can assist in the management of soil fertility in sugarcane companies. This study aimed to evaluate the use of geostatistics and mathematical modeling in the fertilization expense estimative in different relief forms. In an area of 200 ha has been identified two relief forms, one concave and one convex, and the soils collected was at the crossing points of a grid with intervals of 50 m, a total of 623 points. The samples were subjected to chemical analysis and subsequently the data were analyzed using descriptive statistics, geostatistics and mathematical modeling. The results showed that when the relief forms are incorporated into the geostatistical analysis and mathematical modeling, there is an increase in the efficiency of limestone, phosphorus and potassium application in the soil.
