Polyethylene Greenhouses - Constructions

Greenhouse production is still among the most energy-consuming branches of agriculture. Producers are faced with high cost of the operations involved in greenhouse production processes (climate control, fertilizing, irrigation). This is the reason why an optimal combination of energy inputs that will make this production more energy efficient needs to be found. In this paper analyze types of energy inputs in greenhouse production and their share in total energy consumption by using their energy equivalents. Knowing all this inputs enabled calculating of energy efficiency and energy ratio for greenhouse winter lettuce production.
