With the present invention the sea grass Posidonia oceanica is used for the production of organic compost or compost, for agriculture, with co-composting of organic waste of agricultural, animal or industrial units. The procedure applied comprises the collection and transfer of the sea grass to the treatment unit and then mixing with various organic wastes (olive-mill waste, cheese and wine manufacturing waste, sewage sludge etc.) so that the carbon to nitrogen ratio is approximately 30:1 in the product of mixing. These ratios favour the growth of microorganisms, which control the biological composting process and help sea grass, which is slow to break down naturally, to decompose and release its nutrients. The whole procedure lasts 9-12 months, in two phases. The end product, organic compost or compost, for agriculture, is used as a means of plant growth with fertilising properties, as a means to improve and enrich soil, as a means against soil erosion and exhaustion, as a product for land reclamation, as a product suitable for reforestation, as a crop-protective agent, and as organic material suitable to be mixed with metal compounds and minerals from industrial units |
