Carbon fertilisation is the artificial enrichment of the atmosphere of greenhouses with carbon dioxide, an essential nutrient for plants and vegetables. It is used to improve production levels, both from a qualitative and from a quantitative point of view. It is particularly suitable for cold climates and can be used for growing practically all types of vegetables (asparagus, celery, lettuce, tomatoes, aubergines etc.), greenhouse fruit (strawberries) and ornamental plants.

SOL has developed considerable expertise in this field and commercialises its solutions with the ORTOFLOR trademark.
