The mycorrhizated seedlings we produce are subjected to two external controls, one referring to the health of the crop by the Centro de Semillas y Plantas de Vivero of the Diputación General of Aragon (Autonomous Community Government), and every seedling that comes out of our greenhouses has its corresponding phytosanitary passport.

Secondly, the Diputación Provincial of Teruel, through its Agricultural Services, controls the batches of seedlings mycorrhizated by black truffle (Tuber melanosporum), of the different forest species we produce. Each year starting in the autumn and throughout the winter, seedlings from different batches are collected and examined.
These controls have been carried out since 1997 and the number of negative findings and rejections of the batches has been minimal.
We include below an archive with the results of the different controls realized over these years.
