CulturTruf was financed by FranceAgriMer (French Agriculture Ministry) from 2016 to 2019. The objective of this project is to understand how water balance, truffle production, and soil truffle DNA evolve in different orchards of T. melanosporum, T. aestivum, T. aestivum var. uncinatum according to technical itineraries adapted to different climates. The aim is to optimize water management in truffle plantations by coupling basic and applied research approaches. In this sense, this project fully responds to a strong demand from the sector to adapt truffle production to climate change.
