Why controlled mycorrhization?
Mycorrhizae, a symbiotic association between plant and fungus, exist naturally in traditional nurseries. It is most often of mushrooms without interest for the subsequent development of the plants.
In the forest, mycorrhizae are abundant and are necessary for good tree growth. But they disappear very quickly, 1 to 2 years after a clear cut.
Mycorrhizae are also absent in old agricultural lands and in disturbed sites (roads, highways, mines, quarries, industrial wastelands). Under these conditions, traditional seedlings can encounter enormous problems of recovery and growth.
This is why Robin Pépinières has developed controlled mycorhization, under license and control of INRA, to improve the performance of seedlings, and greatly increase their recovery rates in sites under difficult conditions.
What is controlled mycorrhization?
These are mycorrhizal plants with strains (fungi) that are selected. It is this technique that allows seedlings to improve their planting performance.
