Sviluppo di substrati sostenibili a base di compost ottenuti dal recupero di scarti di coltivazione

Soilless crops tend to increase yields using hi-techs combined with safe substrates. Peat is largely used for this purpose since it shows good and constant agronomic features; however, its production and use is unsustainable and boost the global warming. Within SusMedHouse project CNR-ISAFOM developed peat-free alternatives containing compost from crop waste recycling, ensuring an agronomic quality even better than that of peat. Lab-scale production of 5 high-quality compost were carried out using a selection of organic waste including tomato and pepper crop residues. By mixing the most promising compost with a selection of suitable zeolites, up to 8 innovative peat-free growing media (Zeo-Compost) were designed, analyzed and verified in preliminary agronomic tests. The best performing Zeo-Compost will be further tested on-farm at SusMedHouse, an innovative greenhouse currently under construction in Turkey

Le colture fuori suolo sono in grado di aumentare le produzioni utilizzando tecnologie avanzate e substrati di crescita adeguati. La torba è largamente utilizzata per questo scopo poiché mostra caratteristiche agronomiche adeguate e stabili nel tempo; tuttavia, la sua produzione ed utilizzo sono insostenibili poiché contribuiscono al riscaldamento globale.Nell'ambito del progetto SusMedHouse il CNR-ISAFOM ha sviluppato alternative prive di torba a base di compost ottenuti dal recupero degli scarti delle colture, garantendo una qualità agronomica del substrato tendenzialmente superiore a quello della torba. Sono stati prodotti in laboratorio e studiati 5 compost di alta qualità utilizzando selezioni di scarti organici tra i quali i residui di colture di pomodoro e peperone. Mescolando i compost più promettenti con una selezione idonea di zeoliti, sono stati progettati, analizzati e testati in prove agronomiche preliminari 8 substrati innovativi privi di torba (Zeo-Compost).Lo Zeo-Compost più performante, riprodotto a scala aziendale, sarà ulteriormente testato in campo presso SusMedHouse, una serra innovativa in procinto di essere ultimata in Turchia.Soilless crops tend to increase yields using hi-techs combined with safe substrates.
