Aardbei Fossielvrij

The increasing acreage of strawberry under protected conditions has to be cultivated fossil free and sustainably,certainly given the recent rise in energy prices. Commissioned by Kas als Energiebron, WUR and Delphy have described how such a cultivation system looks like. A general description of future strawberry cultivation has been given, current knowledge and knowledge gaps are given, and an with computation model options for further energy saving steps are quantified. Computations are performed for three situations, viz., cultivating a not-illuminated ever-bearing cultivar, an illuminated ever-bearing cultivar, and a low-chill fresh cultivar. Using thoughtful setpoints already leads to considerable energy saving. Furthermore, attention is given to lowering air temperature, increasing relative air humidity, and longer or higher lighting. The consequences for the use of gas, electricity and CO2 are estimated for all situations. The remains an energy demand for heating and lighting, however, these should be supplied from non-fossil sources.
