Avaliação da aplicação de corretivos a lanço auxiliado por comunicação via rádio entre máquinas - um estudo de caso

Abstract

In the agricultural mechanization field, communication between machines has gained popularity, improving agricultural operations. Using a case study, this paper aims to evaluate, the overlap in soil amendments application using radio communication between machines. It also seeks to determine the difference in applied areas and the return on investment for such technology. Three application formats were the focus of the study, including field activities, and controlled bench simulations. The applications consist of: Application A, which accomplishes the real-field application using the machine-to-machine communication system; Application B, performed through simulation without the system; and Application C, which simulates using the intermachine communication system. The finding shows that operations A, B, and C had average overlaps of 4.72%, 4.17%, and 4.73%, respectively. Therefore, the overlap decreasing in applied areas was 13.4%. The reduction in the amount of product for the total overlap considering the simulation conditions was 0.56%, saving about R$ 18.995,2 per equipment. The results indicate that after applying 71 tons of product per machine or after 10 months, ‘the return on investments is given.
