Terroir
“Soil is crammed with bacteria. Its earthy scent is the smell of the chemicals they produce. Petrichor, the smell released by dry ground when it is first touched by rain, is caused in large part by an order of bacteria called the Actinomycetes. The reason that no two soils smell the same is that no two soils have the same bacterial community. Each, so to speak, has its own terroir.”
From “Regenesis” by George Monbiot
