Accuracy and response times of variable rate machines for agricultural defensive application

Otávio Dias da Costa Machado Airton dos Santos Alonço Tiago Rodrigo Francetto Dauto Pivetta Carpes About the authors

The development of precision agriculture and site-specific management were premised on farm machinery precise actuation. However, this performance is still unacquainted. Along this, it was established the aim of describing the performance of this machines, the variables evolved and the applied methods. It was demonstrated that many of the devices are operating with excessive response times, low accuracy and distorted measures. In some cases, it was possible to identify situations with appropriate precision. Thus, it could notice important aspects to be considered, to make a field work indeed to the planed management
