Emissions of an agricultural engine using blends of diesel and hydrous ethanol
Farias, Marcelo Silveira de; Schlosser, José Fernando; Estrada, Javier Solis; Perin, Gismael Francisco; Martini, Alfran TellecheaThe growing global demand of energy, the decrease of petroleum reserves and the current of environmental contamination problems, make it imperative to study renewable energy sources for use in internal combustion engines, in order to decrease the dependence on fossil fuels and reduce emissions of pollutant gases. This study aimed to evaluate the emissions of a diesel-cycle engine of an agricultural tractor that...

Schlosser, José Fernando; Martini, Alfran Tellechea; Farias, Marcelo Silveira de; Bertollo, Gilvan Moisés; Santos, Gustavo Oliveira dosSérie Cadernos de Extensão - Meio Ambiente - UFSM; As inspeções de pulverizadores agrícolas podem ser realizadas de forma obrigatória ou voluntária. Tendo em vista a necessidade de reduzir a contaminação ambiental e elevar a eficiência e qualidade das aplicações de agrotóxicos, diversos trabalhos são desenvolvidos para avaliar quantitativa e qualitativamente os itens básicos dos pulverizadores agrícolas, com o ...
Inspeção técnica de pulverizadores agrícolas conforme a norma ISO 16122
Martini, Alfran TellecheaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES; The primary sector development by the expansion of cultivation areas and the increase in the productive indices promoted the increase of pesticide uses. That reflect in problems related to application inefficiency, making a important point to be studied mainly related to spray precision. Taking account the necessity in reduced the environmenta...
Agronomic characteristics of wheat due to seed treatment and timing of nitrogen...
Ulguim, André da Rosa; Agostinetto, Dirceu; Martini, Alfran Tellechea; Westendorff, Nixon da Rosa; Langaro, Ana CláudiaWheat (Triticum aestivum L.) is the most economically important crop between winter cereals. Two experiments were conducted to evaluate the effect of seed treatment with fungicides to delay crop emergence and influence of nitrogen application time on morphological and physiological variables and yield components of wheat. The first, in the greenhouse and completely randomized design, tested two seed treatments,...
