Aiming to contribute to the implementation of Precision Agriculture in sugar cane crop in Brazil, this project registers two fundamental process: i) to design a sugarcane yield monitor; ii) to map physical and chemical soil attributes. The main objective is to make a correlation with yield data and soil attributes obtained. The system designed uses load cells as a billets weighing instrument set up in the harvester side conveyor before the sugar cane billets are dropped in an in-field trailer. These data together with the geo-referenced position provided by the Differential Global Positioning System (DGPS) set up in the harvester, will allow the elaboration of a digital map, which will represent the yield area. This system is being tested under laboratory conditions for further field tests. The physical and chemical soil attribute maps were obtained using a 50 x 50 m grid sampling, obtained using a undisturbed soil sampler, in a 43 ha area plot of a sugar plantation (Usina So Joo), located in Araras, So Paulo State, Brazil. The Geostatistic techniques will be used to obtain the soil properties map.
