Custódio, Tiago Vega; Spagnolo, Roger Toscan; Oldoni, André; dos Reis, Ângelo Vieira; Machado, Antônio Lilles TavaresA agricultura familiar é responsável por uma parcela importante da produção agrícola do país. Entretanto, se depara com uma deficiência no que tange às máquinas agrícolas, sendo uma das dificuldades construir canteiros e depositar fertilizantes. Assim, muitas atividades são executadas manualmente, reduzindo a produtividade. Neste estudo, objetiva-se estabelecer a estrutura funcional de um sistema mecanizado cap...
ORGANIC PRODUCTION: PROPERTIES CHARACTERIZATION AND MECHANICAL SITUATION ON WEE...
Spagnolo, Roger Toscan; Oldoni, André; Custódio, Tiago Vega; Tavares Machado, Antônio Lilles; dos Reis, Ângelo VieiraIn the last few decades, there has been a significant increase in organic products demand, which are produced without pesticides use. In Rio Grande do Sul, the Sul-Ecológica Cooperative, composed by 250 families, is the representative for organic products production and sails and was a reference to embody this study. The work aimed to characterize the production standards used by organic farmers for their prope...
Safety index for agricultural tractors
Oldoni, André; Spagnolo, Roger Toscan; Morais, César Silva de; Rocha, Marco Aurélio Nunes da; Machado, Antônio Lilles Tavares; Reis, Ângelo Vieira dosThe manufacture of agricultural machinery should follow the criteria that specify the existence and standardization of components and security systems, so as to make them safe. The aim of this study was to establish a checklist to classify agricultural tractors according to a safety index. The list was obtained through literature review and by checking norms and articles on Components and Security Systems (CSSs...
Evaluation of a variable rate fertilizer application system adpted to coffee crop
de Barros, Murilo Machado; Volpato, Carlos Eduardo Silva; Silva, Flávio Castro da; Palma, Marcos Antônio Zambillo; Spagnolo, Roger ToscanAn extremely important factor in the production of coffee and other crops is the distribution of fertilizers on the soil, because the efficient use of this technique may increase productivity, reduces production costs and environmental impacts. Precision Agriculture is an important tool to be used, that aids the achievement of localized and rational application of fertilizers, increasing the management activiti...

Spagnolo, Roger Toscan; Zambillo Palma, Marcos Antonio; Silva Volpato, Carlos Eduardo; Barbosa, Jackson Antonio; Alencar Nunes, RodrigoThe main objective of this study was to evaluate the operating performance of an agricultural tractor operating with new and worn tires for distinct tire weight conditions and three inflation pressures. The tests were conducted at the experimental unit of the Department of Animal Science, Federal University of Lavras, with average soil moisture of 25.6% and 14.97 t ha-1 dry matter at the time of testing. The 4x...
