Modern archaeologists have excavated garden sites and urban domains to reveal the agricultural staples of Pompeii's economy. Pompeii was fortunate to have had fertile soil for crop cultivation. The soils surrounding Mount Vesuvius preceding its eruption have been revealed to have had good water-retention capabilities, implying productive agriculture. The Tyrrhenian Sea's airflow provided hydration to the soil despite the hot, dry climate. Barley, wheat, and millet were all produced along with wine and olive oil, in abundance for export to other regions.
