What soil biology tests say about plant mycorrhizal colonisation

摘要

In the third article in the series on the contribution mycorrhizae fungi make to plant health and production Larry Simpson reviews the relationship between different tests and root mycorrhizal colonisation. Unfortunately, mycorrhizal fungi are invisible to the naked eye, so determining their presence in a field or on a crop is essentially impossible without a microscope. The simple solution is to send root samples from crops and grasses from the target field to a qualified lab for professional analysis. It is important that you choose a lab carefully, as not all plant or soil labs perform this kind of testing. To avoid the possibility of inaccurate root colonisation testing, look for a lab specialising in mycorrhizal analysis.
