HISTORY & CONTEXT

The aquaponics system at SWUAS (Fachbereich Agrarwirtschaft der Fachhochschule Südwestfalen) was implemented for research purposes. The installation started in May 2015. Regarding the aquaculture system, European catfish are held in three 1.1 cubic meter tanks, equipped with filters, feeders and warm water. The fish production is connected to the floating hydroponic system hosted in the greenhouse next door, growing in deep water culture beds (DWC). Aquaponics seeks for resource efficiency by recirculating the water between the two systems: the water from fish farming (aquaculture) flows into the plant basins (hydroponics) where the fish residues are used as fertilizers.

AGRICULTURAL & AQUACULTURAL CHARACTERISTICS

Crops: Lettuce (Salanova cook RZ), Lemon balm and Basil (African blue)

Fish: European catfish (Silurus glanis)

Techniques: Aquaponics production: Aquaculture tanks with UV disinfection and filters (biological & mechanical) + Floating hydroponic production with wooden beds

Irrigation: Well water (Elevated amount of calcium carbonate)– Recirculation – Automatic irrigation (Tap water is available)

Use of renewable resources: –

Sustainable practices: Pesticides-free – Integrated pest management – Local production – Minimization of water consumption – Sustainable production of protein sources

HISTORY & CONTEXT

PELLEROSSA is born as the first eco-friendly tomato in the region of Emilia – Romagna by employing agronomic techniques that respect the environment. They are promoted as “100% sustainable” since it grows in a clump of earth wrapped with coconut fiber in a high greenhouse, solid and bright. Every day, hour after hour, is fed with natural substances in order to grow healthy and tasty.

AGRICULTURAL CHARACTERISTICS

Crops: 2 varieties of tomato

Techniques: Hydroponic rockwool production

Irrigation: Use of well water – Drip irrigation – Use of fertigation (NPK)

Use of renewable resources: –

Sustainable practices: Pesticides-free (Integrated pest management with benefitial insects) – Local production – Minimization of water consumtpion – Use of residual hot water from the bioenergy plant

Visit to Serra Pellerossa

IMG_3672.JPG

Today we visited the periruban farm of IPOM Pellerossa in the outskirts of Bologna. This farm employs technological innovation to minimize the environmental impact of their tomato production. In particular, the name of the farm “Pellerossa” refers to a local variety of tomato that the farm recovered. This is one the case studies for technological innovation in SustUrbanFoods.
