The HORTISED project aims at demonstrate the suitability of dredged remediated sediments as an alternative for the preparation of growing media in horticulture.Previous EU projects demonstrated that phytoremediation adopting the AGRIPORT technique can be used to remediate moderately polluted marine sediments, and convert them in a technosoil suitable for revegetation of terrestrial environments, and as a substrate for plant nursery. Food crops production requires absolute indications of a safe use in terms of absence of risks for human health and environment; the potentials of the remediated sediments for horticultural production in terms of products quality and human health need a full scale demonstration.In the HORTISED project, the decontaminated sediments, will be submitted to three months landfarming process.

Abstract
The HORTISED project aims at demonstrate the suitability of dredged remediated sediments as an alternative for the preparation of growing media in horticulture.Previous EU projects demonstrated that phytoremediation adopting the AGRIPORT technique can be used to remediate moderately polluted marine sediments, and convert them in a technosoil suitable for revegetation of terrestrial environments, and as a substrate for plant nursery. Food crops production requires absolute indications of a safe use in terms of absence of risks for human health and environment; the potentials of the remediated sediments for horticultural production in terms of products quality and human health need a full scale demonstration.In the HORTISED project, the decontaminated sediments, will be submitted to three months landfarming process. Strawberry and pomegranate will be taken as model plants for the demonstration trials. For fruit production, certified plants of a pomegranate (Valenciana) and two strawberry (Camarosa, Monterey) cultivars will be grown in containers with 3 different substrates (100% sediments, 50% sediment/ordinary, 100% ordinary). Each thesis will be replicated in 3 blocks, each block containing 10 (strawberry) or 5 plants (pomegranate). Leaf and fruit samples will be collected and different parameters will be monitored and analyzed on the sediment- and peat-based growth media, on plants and fruits. Furthermore fruit samples will be used for biochemical analysis and for sensorial panel taste analysis. Besides, cuttings from shoots of pomegranate cultivars (Valenciana and Mollar de Elche) will be grown on the same substrates as described above; each thesis will be replicated in 3 blocks, each block containing 10 cuttings. Different parameters will be monitored and analyzed on the growth media, on cuttings and on leaves.A completely random design for all trials will be adopted; ANOVA and other statistical analysis will be performed on all samples for 2 consecutive years.
