Fertilisation Vs. Mycorrhiza
•However, mycorrhizae react very sensitively to nitrogen: at high fertilisation levels (as
wanted in tree
nurseries, etc.) these fungi simply die (viz. AFZ
8, 1992).
•
•Previously, in order to protect the existing mycorrhizae, no efficient fertilisation was possible at the same time when mycorrhization took place. In later stages of the cultivation the possibilities of additional fertilisation
were highly restricted.
