There are quite a few farms and projects that are worth visiting but most will require a vehicle:
- l'Asino e la luna: located in Cerveteri about 45mins north of Rome along the coast. They are mostly focusing on water and have interesting collaborations with local companies that have sponsored the install and maintenance of many fruit trees in their food forests.
- la scoscesa which is owned and operated by lorenzo Costa who is a member on here as well. Located in gaiola in chianti near Siena. It's an olive grove with vegetable production on very rocky and steep terrain. Lorenzo is the main reference on water management in Italy so he has done a lot of water related enhancements on his property
- ortoforesta run by Dario cortese near Florence with intense veggie production.
- AZ agricola isidi near Lago di Iseo in northern Italy is a beautiful project run by Matteo mazzola, does many interesting things.
I'm not sure you can stay at any of these but might be worth asking. Quite a lot of YouTube content on several of these, perhaps the auto translated subtitles could help you learn more.
