As part of the European BIOBOOST-PRO project, Botany is investigating the potential of circular fertilisers as an alternative to conventional mineral fertilisers in hydroponic cultivation.


The first greenhouse trials with baby-leaf lettuce have shown promising results. The biobased treatment achieved 9.8% higher dry biomass per plant compared with conventional fertilisation. Both biobased treatments also resulted in higher estimated fresh biomass yields.


These initial findings highlight the potential of biobased fertilisers for more sustainable hydroponic cultivation. At the same time, further optimisation of nutrient balance and pH stability remains important.
