Rationalization of energy expenditure in greenhouses: what technical and future solutions?
Through its structure, equipment and management, the greenhouse contributes to the resilience of market garden crops. Energy, one of the main cost items, enables the climatic optimization necessary for crop earliness, productivity, quality and sanitary management. However, its dependence on fossil fuels raises questions at a time when energy sobriety and the decarbonization of agriculture are the order of the day. This conference will analyze existing solutions based on equipment and alternative energy sources. It will be followed by feedback from experiments on tomatoes and cucumbers, which have different climate management strategies. The role of heating on the microclimate in the vicinity of the fruit will be discussed in relation to the risk of condensation. Finally, at the ...
The greenhouse, through its structure, equipment and management, contributes to the resilience of market garden crops. Energy, one of the main cost items, allows the climate optimization necessary for the precocity, productivity, quality and health management of crops. However, its dependence on fossil fuels is questionable at a time of energy sobriety and the decarbonization of agriculture. This conference will analyze existing solutions around equipment and alternative energy sources. It will be followed by feedback from experiments on tomatoes and cucumbers whose climate management strategies differ. An update will be made on the role of heating on the microclimate in the vicinity of the fruit and will be developed in relation to the risks of condensation. Finally, in view of the complexity of the management system, optimization opportunities will be addressed from the point of view of climate modeling tools and autonomous management of greenhouses.
