Mycorrhizal Fungi; an argument against fungicides.

Today I want to get a little bit deeper into the science of bowling green ecology, but I’m getting a little tired of the Ecology title sequence I stupidly started 9 articles ago. Instead of continuing to label them Ecology 1,2,3…etc, I will give them a tag of their own so that if you’re looking for them on the site you just need to type ecology into the search box.

Mycorrhizal Fungi (mycorrhizae) are specialised fungi that work with our grass plants to form symbiotic relationships with the roots.  Most soils contain these fungi and each type has its own peculiar host preference. (i.e., each plant species has a specific species of mycorrhizae that it prefers to work with).

The name comes from the Latin word mycor meaning fungus and rhiza meaning root. “Mycorrhiza” is the singular form and “mycorrhizae” the plural and, in soil science the name refers to the tissue that forms when fungi and roots develop a symbiotic (mutually beneficial) relationship.

One of the key benefits to our grass plant in this relationship is that it can increase the surface area of the plant roots by 100 or even as much as 1,000 times. On their own, the roots can only impact (draw moisture and nutrition from) about 3% of the soil volume that immediately surrounds them. Mycorrhizae create microscopic threads that effectively extend the root system or at least the impact of the root system.  This means the plant is many times more effective in absorbing water
