In the early 1900’s the truffle production was around 1000 tons/year, and until ten years ago it had dropped to 25 to 30 tons due to the disappearance of what are called “natural” truffle orchards.
Today, the truffle production managed to stabilize and even increase itself thanks to the advent of the mycorrhized truffle plant (90% of the harvested truffles comes from certified truffle oak plantations). |
