Topografia para agricultura de precisão em sistemas de irrigação no manejo da cana-de-açúcar

Abstract

Topography is the sector responsible for gathering the necessary information for design, analysis and decision making in the elaboration of the projects in the most varied irrigation methods. In addition, after the decisions taken and strategies outlined by the sector heads, the topography is also responsible for placing in the field the dimensions and positions of the components that physically manifest the graphic design done in the office. In these operations many sectors are involved, such as Machinery, Irrigation, Planting and Quality Control, the service is always interdependent linked to topography in the various stages of the work progress process. Since the initial planialtimetric survey to the planting and review of the leases carried out in the period called cane plant, recently implanted the irrigation system and observing if it matches with the expected. In order to prepare the projects for the implementation of new fields, plant renewals and changes in the sugarcane fields of the company, the Topography sector is indispensable, ensuring the accuracy and quality of services, guiding the work of other sectors and giving results in the final stage. The industry has sufficient technology to enable qualified professionals and equipment to promote the success of operations planning and conducting works. Using Trimble RTK GPS, Topcon Total Stations, Garmin GPS and Computer Software such as Topograph, AutoCAD and AgroCAD, the projects were developed by managing the tools and field staff, which were supervised by the sector coordinator who participated in both situations, planning and execution in the field. In order to make it even more precise and less costly, a system of automation of machines was implanted in the grooving operation, where, through software and GPS equipment, the operation is performed by coordinating the machine in the furrow lines automatically, guiding its positions and design limits.
