3. MONITORING OF SOYBEAN MECHANICAL HARVESTING AS A FUNCTION OF PLOT SHAPES
ABSTRACT: Information on harvester performance is important in the management and optimization of mechanized agricultural systems. In this sense, the aim of this study was to monitor the operation quality of soybean mechanical harvesting in different plot shapes by means of statistical process control. The harvest was carried out in an agricultural area of a

7. Dioxide carbon emission from different soil tillage in the sugarcane plantation / Emissão de dióxido de carbono após diferentes sistemas de preparo do solo na cultura da cana-de-açúcar
The annual emissions of carbon dioxide (CO2), considered the greenhouse gas (GHG) more important, increased around 80% between 1970 and 2004. This increment mainly due to the use of fossil fuels, and agriculture as emissions from land use change. Land use management is an important tool to GHG emissions decrease. Agricultural soils can be a source or reservo

8. Modelos de simulação para análise e apoio à decisão nos processos de corte mecanizado, carregamento e transporte no agronegócio da cana-de-açúcar / Simulation models for analysis and decision support in the processes of cutting, loading and transport in the agribusiness of cane sugar
In the current days sugarcane occupies an area of approximately 10,5 % of all the Brazilian agricultural land, with an estimated production for the 2008/2009 crop of 528 million t. In the sugarcane production process, the harvest highlights due its high costs, representing approximately 35% of the sugarcane production costs, besides the addition of operation
