Abstract The Dutch greenhouse horticultural sector has committed itself to reach a (practically) zero emission for
nutrients and plant protection products at latest in 2027. A zero emission production strategy is demonstrated
for the production of sweet pepper (Maranello) on either Rockwool and coco peat. Readily available technologies
and strategies, like ozonation for disinfection of recirculation water and Uptake Analysis for control of nutrients, were combined to reach this goal, together with a newly developed strategy to minimise discharge of water, nutrients and plant protection products at the end-of-season crop change. Productivity on Rockwool substrate (28.1 kg/m2) was slightly higher than on coco peat (26.5 kg/m2), due to less generative steering on the coco peat substrate from the start of the cropping season. Quality of the fruits was good on both substrates. Technical failure of equipment caused overflow of drain tanks (3.8% on Rockwool, 0.7% on coco peat), but this did not significantly reduce the amount of sodium in the water (main reason for discharge). No other water quality parameters were observed that could have negatively influenced productivity.
