Within the Call for Capitalisation however, ReNu2Farm also started exploring the horticulture as a target group of RDFs, as it is the second biggest market for mineral fertilisers. It is of utmost importance to also understand the agronomical impacts of the use of RDFs. The use of RDFs may be very beneficial, provided that also horticulture crop yields can be maintained and there are no negative effects on the crops. Collected data, as well as results from the field trials on the use of RDFs in agriculture cannot be transposed to soilless cultivation in horticulture. Gathering additional results taking into account the specificities of this cultivation model is necessary. Therefore, ReNu2Farm performed some pot and greenhouse trials with RDFs in different crops.
