Development of Sustainable Compost- Based Substrates from Crop Waste Recycling Autori: Roberto Altieri e Alessandro Esposito
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.
