White truffle plants

The ideal soil for the Tuber magnatum is rich in marlstone and limestone, with an altitude of no more than 700 m a.s.l., sufficiently aerate but not excessively permeable. The outer layers must be quite humid even in the dry months. The soil must be quite rich in limestone, poor in phosphorous and nitrogen, rich in potassium, with a PH between 6.8 and 8.5, poor in organic matter. It must enjoy spring and summer showers and must be preferrably in proximity of a non-stagnant watercourse on a valley floor, and must present moderate inclination.

Truffles thrive when a specific relationship between the environment, the chemical composition and humidity of the soil and the climate occurs.

This type of soil is ideal for the following host trees as well:
