Water and truffles

We’ve been analyzing truffles at microscope. Each week new batches arrive to the lab in Barcelona and it’s amazing how they reach maturity as weeks go by, with more and more formed brown spores inside.
Anyway we can say there’s almost no truffle season in Spain, at least wild truffle, as the only source for truffles are truffle farmers with irrigation system, and they are a few. Majority of truffieres in our country have no irrigation and water is becoming the paradigm in truffle farming.
Last week we visit a truffle orchard that they install the watering system in the first week of july, but it was too late! They harvest nothing, as the spring and june had been pretty dry up.
The challenge is not just being able to water but how to water, and it will depend on the soil texture, etc. I’ve seen so many truffleres dissapear to irrigate too much, and in some truffle orchards with irrigation, as years go by, truffle production in kilos could be the same, but truffles become smaller…more research should be done on this issue.
I would love to hear if some of you have some comments and results on your truffieres…

All the best,

Marcos S. Morcillo
