RESUMO

Brazil plays an important role in world agricultural production. The adoption of technologies which allow the increase of food production with improving quality in addition to natural resources conservation is important for agribusiness development, and Precision Agriculture ¿ PA stands out as an option to aid the achievement of these goals. The aim of this work was to investigate the Adoption of PA, as well as the factors related to its adoption by farmers in Rio Grande do Sul, Brazil. With this purpose, an online survey was sent to PA adopters. Descriptive analysis allowed the characterization of the PA adopters and the identification of the most adopted PA tools, while factor analysis followed by multiple linear regression were used in order to verify users¿ perception regarding PA technology attributes. The results show a PA adoption growth and an average time of adoption of 4.3 years. PA adopters have a high level of formal education, use several sources of information, have a predominantly agricultural income and cultivate large areas. The most adopted PA tools used for growing soybeans, maize and wheat are grid soil sampling, variable rate application and lightbar guidance. It was noted that PA adoption is highly dependent on PA services. The number of PA tools adopted is positive associated with the size of cultivated areas, years of PA use, agricultural income and investments in PA. PA technology attributes ¿ relative advantage, observability, compatibility and trialability ¿ determine 48% of the PA adopters¿ satisfaction, being relative advantage of technology the factor of greatest explicative potential. The recent growth of PA adoption by Brazilian farmers shows emerging opportunities for research development which may contribute with industry and government institutions on PF diffusion.
