2 Conventional agriculture Deal with the entire are as it is homogeneous..

3 ...but it never is. Corn yield

4 Precision agriculture Different from the average agriculture... PA is a management approach that takes into account spatial the variability within the fields and aims to take advantage of such heterogeneity.

5 Site-specific management: Precision Agriculture Allows more than one input recommendation for each field: Hibrid and plant population (G1) and (G2) Fertilization standards (A1) and (A2) Pesticides standards (D1) and (D2) D1 G1 D2 A1 G2 x A2

6 Reduce input needs (pesticides) Increase crop yields Improve product quality Higher operational eficiency Profit increases Fonte: Brodbeck, 2010

7 When talking about PA in Brazil today: Management of soil correction and soil fertilization via variable-rate application, primarily of lime, gypsum, potassium and phosphorus Based on georeferenced grid sampling Considering only soil fertility

8 Grid samplings 10 samples/ha 1 sample/1.5 ha

9 Tonnes/ha Lime application 10 samples/ha 1 sample/1.5 ha

10 What needs to be done is: Crop management based on detailed and accurate spatial information about soil, plants, terrain, goals, etc... that is, looking for the whole cropping

11 Main objective: to develop techniques and equipment to assist in the analysis of the production system as a whole, according to the spatial variability of cropping areas, thus, optimizing profits to the growers and reducing environmental impacts Mainly foccusing on sugarcane production

12 Research efforts: 1. Proximal soil sensing to decrease expends with soil analyses and to guide variable-rate fertilizers application 2. Proximal plant sensing to identify spatial issues and to guide site-specific treatments 3. To develop equipments and methods to allow spatial evaluations about the factors related to sugarcane production 4. Development a practical approach for delineating management zones
