Use of co-composted materials as components of substrates mix for plant nursing. Deliverable action B3

Once the co-composting trial, a cultivation phase was planned to evaluate the effect of different substrates obtained assembling the obtained materials on the growth of 2 ornamental container-grown species. Due to the delays in granting authorizations for the preparation of compost in Italy, the consortium decided to carry out 2 different field trials. The first one (Trial 1) using co-compost from Czechia; the second one (Trial 2) using compost produced in Italy. Trial 1 started in October 2020 and was carried out either at GORINI nursery company in Pistoia (Italy) and at EPS greenhouse in Kunovice (Czech Republic). The Trial 2 was planned six months later and carried out only at GORINI nursery in Pistoia. One last trial was conducted with technosols provided by MCM, to understand if these components could improve cultivation of ornamental plants in containers (Trial MCM).
