Key concepts
- Soil biodiversity supports multiple functions.
- Economic value needs a defined outcome.
- Observational associations are not causal estimates.
The lesson
Soil organisms participate in processes relevant to agriculture, and fungi have diverse roles within that community. Connecting a process to financial value requires a defined outcome, a comparison and measured costs.
MycoIlm records sightings and optional contextual metrics. These records do not establish that fungi caused a change in cattle growth, pasture productivity or input efficiency. Weather, management and sampling can differ at the same time.

A moment to apply it
Put it into practice
Write a research question with a defined outcome and comparison group. List two factors, besides fungi, that could influence that outcome.
Keep in mind
Keep observations descriptive until an appropriate study supports a causal or financial conclusion.
Educational material. Check the linked reading and distinguish general principles from evidence about a particular specimen or field site. Lessons do not establish edibility or causal effects on livestock performance.
