Abstract
It has been documented that an increased supply of carbon dioxide will result in a growth increase in greenhouse cultivation at an average of 26%. CO{sub 2} can be produced by special natural gas burners placed in the greenhouse or in an existing central heating boiler with a pipe system leading to the building. A plant producing CO{sub 2} fertilization is described. Calculations of available CO{sub 2} must be estimated taking into account the absorption rate in the greenhouse plants and the amount of loss through ventilation windows. Supply varies significantly according to ventilation and weather conditions. Measurements have shown, it is claimed, that pollution levels from using combustion gases from natural gas for CO{sub 2} fertilization are very low. Computerized control systems can help to achieve growth increase with low CO{sub 2} consumption. Use of a hot water accumulator in relation to a central boiler can help to optimize heat supply and CO{sub 2} fertilization. A 90 m{sup 3} hot-water tank per hectar greenhouse area can help to keep the desired level of CO{sub 2}. Calculations have shown that the cost of retaining a 340 ppm CO{sub 2} level throughout the season is ca. 35% lower when using a
