Acurácia e tempos de resposta de máquinas para aplicação de defensivos agrícolas à taxa variável

Abstract: RESUMO INTRODUÇÃOA Agricultura de Precisão (AP) moderna desenvolveu-se como um novo sistema de produção agrícola, com o advento do geo-referenciamento dos atributos dos fatores de produção. Em seus primórdios, segundo MOLIN (1997), o embasamento do sistema estava na análise da variabilidade espacial dos fatores de produção, especialmente do solo. Essa análise permitia então a tomada de decisões para a aplicação dos insumos. Já nos últimos 20 anos, segundo ANDRADE-SANCHEZ & HEUN (2010), o estudo da variabilidad… Show more

“…Alvarenga et al (2013) developed an automatic droplet spectrum control system based on servomotors and reported that other systems based on electric valves can present more viable response time. In the present study, the response times obtained shorter than the ones recorded by Machado et al (2015) for other automated spray systems.…”

“…However, to perform VRA in an effective and viable manner, equipment must be developed, and specific evaluation parameters must be determined to meet the crop specifications [9]. Additionally, knowledge of the operational quality of the equipment for VRA is not widespread [10].…”

“…Functions such as variable-rate application (VRA), as assessed by MACHADO et al (2015), geo referenced applications, monitoring and operation control by means of on-board devices such as productivity sensors, and complex drives are examples of applications that feed this demand and are correlated with the advancement of precision agriculture (PA). One of the alternative drives already explored by manufacturers is the electric drive (KARNER et al 2012).…”
