“…30 Italian legislation considers these plant biomasses as a special kind of solid waste material to be disposed to landfills, thus resulting in an enormous loss of organic materials, nutrients and useful biomolecules, 31 with additional problems associated with their transport to landfills. Previous studies have demonstrated that Posidonia residue-based compost showed positive chemical features and the absence of phytotoxicity phenomena, 32,33 and has been used in horticulture for greenhouse tomato 34,35 and lettuce 36,37 cultivation, and for nursery production. 38 Ocimum basilicum L., known as sweet basil, has been used as indicator crop in relation to its high economic value and its importance for greenhouse production.…”

“…Previous studies showed the positive chemical features and the absence of phytotoxicity phenomena (Cocozza et al, 2011a) and the good overall qualities of posidonia residue-based compost (Orquin et al, 2001;Saidi et al, 2009). Posidoniabased compost has been used in horticulture for greenhouse tomato (Castaldi and Melis, 2004;Verlodt et al, 1984) and lettuce (Gizas et al, 2012) cultivation, and for nursery production (Ben Jenana et al, 2009).…”

Posidonia [Posidonia oceanica (L.) Delile] is a marine phanerogam endemic of the Mediterranean Sea that grows all along the coast forming extensive underwater meadows. Senescent posidonia leaves, together with fibers (residues of rhizomes and decomposed leaves), periodically accumulate along Mediterranean beaches, covering vast areas of coast. Removal and disposal of these large volumes of plant biomasses represent a high cost for local administrations. Therefore, in this experiment, beached residues of posidonia were composted with olive pruning and green wastes with the objective to assess the efficacy of posidonia-based compost (63% on a volume basis) as a peat replacement. The compost was then mixed with a peat-based commercial substrate at rates of 0% (C0, pure peat-based commercial substrate tested as control), 25% (C25), 50% (C50), 75% (C75), and 100% (C100, pure posidonia-based compost) v/v. Mixtures were used as growing media to produce lettuce seedlings for transplant. Two lettuce cultivars (8511RZ and Satine) were tested. Main physical and chemical properties of the five growing media, shoot and root fresh and dry weight, leaf area, root morphology, and elemental leaf tissue composition were studied. Growing media containing posidonia-based compost, C25 and C50 in particular, showed good physical properties. Increasing compost proportions in the mixtures resulted in enhanced: 1) availability of macro- and micronutrients in the growing media; and 2) overall growth parameters of lettuce seedlings, in particular for the cultivar Satine. In conclusion, posidonia-based compost shows a considerable potential as a peat substitute in horticultural substrates; posidonia residues are a low-cost renewable material. In growing media for lettuce seedlings production, posidonia-based compost could be used as a complement to peat at a rate of 25% or 50% to obtain optimal physical properties and to limit the negative effects of high B content, which are typical of posidonia residues.

“…In the whole Mediterranean area there are different experiences of composting, thanks to the high presence of beached detritus of P. oceanica along the coasts. In Tunisia, for example, the compost was used as substrate for the cultivation of vegetables and, in particular, tomato (Verlodt & al. 1983).…”

The paleoendemic seagrass Posidonia oceanica (L.) Delile represents a key species of the most important and productive ecosystem in subtidal habitats of the Mediterranean Sea. This species is the most common seagrass in Sicily where it forms dense and extensive beds, which are characterized by high coverage and primary production values. The beaching of P. oceanica detritus (banquette) can be an environmental, economic and social problem, if it comes into conflict with a number of activities (tourism, bathing establishments, etc.). Even though seagrasses play a fundamental ecological role in limiting coastal erosion and promoting the origin of the coastal dunes, the presence of P. oceanica detritus along the coasts can negatively decrease the tourism value of beaches. As a result, according to national and regional laws and guidelines, local authorities are required to remove banquette and to accumulate it in landfills. In this survey, the ancient exploitation and current uses of P. oceanica detritus are reported according to literature data. Moreover P. oceanica detritus were used to replace soil in an experimental installation located at the University of Palermo. Meanwhile, continuous temperature values measurements by using hobo data logger sensors were carried out. The results confirm the thermal insulation role of this material and highlight potential applications in the field of Soil Bioengineering.
