Análise das características reológicas no escoamento de misturas utilizadas no tratamento preventivo do cultivo da soja

Abstract

As it is guaranteed the autonomy to the rural producer to form the mixture of pesticides in a personalized way ends up appearing a great variety of possible combinations and characteristics of mixture. The mechanization of the procedures performed in agriculture created a very strong identification with classic industrial processes, such as pumping and storage tanks, in their proper scale. In this context, this work aimed to analyze the rheological behavior of agricultural mixtures composed of several pesticides and to create a perspective of the influence that these mixtures have on the spraying operation. Classical methods of analysis of experimental results, like rheograms and viscosity diagrams, were used as a function of strain rate. In general, this study provides relevant information for farmers and researchers on the viscosity and definition of Newtonian behavior for the analyzed agricultural mixtures, and the results can be extended to other compositions of agricultural blend.
