A soil amendment is easy to oversell. Here is where our evidence stops.
The is real and it is jointly documented. But it should be understood precisely, because it is regularly misread.
On safety
The products are documented pathogen-free and low in heavy metals. The mycorrhizal product is classified non-hazardous under EC guidelines, non-toxic and biodegradable. Pesticides and radioactive materials are not detected in the conditioner. These classifications also ease the import pathway for a national programme.
On what will not work
Phosphorus-based fertiliser inhibits the mycorrhiza altogether — the two cannot be used together
Brassicas, amaranths and carnations form no mycorrhizal association and need a different approach
The first few weeks show weak growth. That is the fungus being paid before it delivers, and it is expected
Where irrigation concentrates salt at root level before the mycorrhiza establishes, early setbacks occur — as they did at Al Jouf
