Sicily has long been noted for its fertile soil due to the volcanic eruptions in the past and present. The local agriculture is also helped by the pleasant climate of the island. The main agricultural products are wheat, citrons, oranges (Arancia Rossa di Sicilia IGP), lemons, tomatoes (Pomodoro di Pachino IGP), olives, olive oil, artichokes, Opuntia ficus-indica (Fico d'India dell'Etna DOP), almonds, grapes, pistachios (Pistacchio di Bronte DOP) and wine. Cattle and sheep are raised. The cheese productions are particularly important thanks to the Ragusano DOP and the Pecorino Siciliano DOP. Ragusa is noted for its honey (Miele Ibleo) and chocolate (Cioccolato di Modica IGP) productions.
