Laboratory of Progressive Agricultural Engineering

The main is to undertake basic, applied and adaptive research leading to the development and improvement of equipment, technology and processes for agricultural and rural sectors.  Comprises a substantial capacity in terms of laboratories, instruments, support workshops, library and computer infrastructure enabling to undertake a wide range of agricultural engineering projects.

RESEARCH ACTIVITIES

  • Soil, environment and energy-saving tillage, seeding and harvesting technologies and machines and investigation of their processes, optimization design and technological parameters;
  • Analysis of systems for precision agriculture;
  • Energy crops harvesting and preparation for fuel technologies qualitatively, energy and environmental assessment, optimization of plant biomass preparation and usage for conversion methods and technical means.
