Üzemi méret és energiaköltség a zöldséghajtatásban

Tegla, Zsolt - In: GAZDÁLKODÁS: Scientific Journal on Agricultural Economics 54 (2010) 2

Magyarországon a termálenergiára és a megújuló energiára (faapríték-fűtés) alapozott hajtatásos zöldségtermelés kilátásai biztatóak. A zöldséghajtatásban elsősorban a 3 és 5 hektáros méretű üzemek azok, amelyek geotermikus energiával és biomasszával fűtve képesek...
