Presentation made by Gavin Kernaghan for the Spore Amendments: Truffle Wells, Traps & Trenches – TRAPI webinar on February 20 2023
Successful production of truffles requires critical information on optimal soil and climate conditions. These conditions dictate where truffles should be introduced, and the amendments needed to assure adequate yields. In this TRAPI webinar we discuss the optimal conditions for both European truffles and native North American truffles. Irrigation is a critical amendment to achieve optimal soil moisture and to extend yield potential into arid environments. We review what little is known about moisture requirements and discuss well-tested methods used to schedule irrigation to achieve target moisture conditions.
Webinar recorded on 2/20/2023 under the TRAPI umbrella.
Topic discussed:
Life history of Tuber melanosporum.
Spore amendments and truffle mating types.
A grower’s perspective on spore amendments.
Can we breed truffles?

Study on the impact of irrigation treatments on the association of black truffle presented by Becky Loverock at the NATGA Fall Congress 2021
The gastronomic relevance and price of truffles are related mainly to its unique aroma. In this study, we explore the impact that different volatile compounds have on the aroma quality of fresh truffles using gas chromatography-mass spectrometry (GC-MS).
The objective of my presentation is to illustrate several researches on truffle life cycle and truffle cultivation developed in France. I will briefly present our knowledge on the sexual reproduction of the black truffle and then I will highlight the main results of the national research program CulturTruf. In this project we have experimented with watering truffle beds by monitoring the soil water potential (SWP) and have shown that this improves truffle production. I will show how we have developed an innovation (pF Tracer) allowing truffle growers to equip themselves with probes to follow the pF. Finally, I will present our latest remarkable results on the culture of the white truffle Tuber magnatum.
