Chicken fatling production hall ventilation system energy efficiency improvement with variable frequency control for fans / Frekventna regulacija rada ventilatora kao mera povećanja energetske efikasnosti sistema proizvodne hale farme tova pilića
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2009)
In past few years there were a notable number of ventilation systems applications working with variable air volume (VAV). Accessibility, simplicity and low-cost of frequency regulation equipment implementation in ventilation ...
Exploitational and energetic aspects of soil preparation for orchard establishment / Eksploatacioni i energetski aspekti pripreme zemljišta za podizanje višegodišnjih zasada
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2007)
Intensive soil preparation including both mechanical and human labor is required prior to the planting and establishment of orchards. Due to energy deficiency during the past years attention was focused on rational technology ...
Environmental consequences of plant utilization for energy / Ekološke posledice upotrebe biljaka za dobijanje energije
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2007)
Global food and fossil energy consumption are on trajectories to double by 2050. Fossil fuel use has pushed atmospheric carbon dioxide higher than at any time during the past half-million years. While fossil fuels still ...
Preparation and potential of pruning residues in orchards and vineyards as energetic material / Priprema i potencijal ostataka rezidbe u voćnjacima i vinogradima kao energetskog materijala
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2007)
Huge amounts of plant remains are obtained following pruning, an essential agricultural practice measure during the exploitation of orchards and vineyards. Different pruning modes are employed depending on the size of the ...
Greenhouse vegetable production on the small scale farms / Proizvodnja povrća u zaštićenom prostoru na malom posedu
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2011)
In this paper a way of improving the greenhouse production on the small scale or family farms is presented. A new type of round greenhouse construction is introduced that should lead to more energy, economy and ecology ...
