CO2-gebruik moet efficiënter: Mogelijke opties voor zuiniger CO2-gebruik

The CO2 emissions of the entire horticultural sector must be reduced to 4.3 to 4.8 Mton CO2 equivalents by 2030, almost half of those in 2020. This makes the efficient use of CO2 by the crop and the minimization of the loss of CO2 of great importance. Previous KaE research has shown that it is possible to have an acceptable crop yield with a lower CO2 dosage than usual. In this study, specific attention was paid to the hitherto relatively unexposed CO2 problems in chrysanthemum and sweet pepper cultivation. Through discussions with the sector and through a study of previous research for these crops, knowledge has been built up on the role of CO2 in growth, product quality and on the efficiency of the CO2 deployment. With already available data, the growth models for chrysanthemum and sweet pepper have been calibrated, in order to predict promising strategies for efficient CO2 use. The strategies have been evaluated together with the sector. A number of strategies offer a perspective for cultivation practice, in being cost-effective with concomitantly reduced CO2 use and loss. The strategies require customization for every company.
