| Abstract:
One of the main constraints for a large scale use of Arbuscular Mycorrhizal Fungi (AMF) in plant production is the availability of commercial inoculants. To date, some companies have totally or partially achieved a procedure for a commercial production of AMF inoculants. However, their utilization at a commercial level in Europe is still limited because of their incompatibility with the large use of chemical inputs such as fertilizers and pesticides. The best way to promote utilization of AMF inoculants is to determine beforehand the optimal conditions compatible with their utilization. The BIORIZE company produces a range of commercial AMF inoculants (ENDORIZE) in a granular form using calcined clay as carrier, well adapted to be used in nursery, in different systems of plant production. To promote utilization of these inoculants, BIORIZE company has set up a wide range of experiments with technical centers and private nurseries to determine the best conditions for the use of these AMF inoculants. The utilization of a commercial inoculant ENDORIZE after soil disinfection in nursery permits to overcome many problems such as heterogeneity, low growth and recovery; AMF inoculation in container systems (peat based media), during plant propagation must be done under low soluble phosphorus fertilizer and special fungicide regime for achieving good plant mycorrhization ; this ensures a better rate of success in plant production, high plant quality and a guaranty, for plant recovery when transplanting into field. Our results show that the utilization of the commercial AMF inoculants ENDORIZE is technicaly feasible and that plant production in nursery can benefit from this biotechnology. | |
