In which successional stage is fungi most dominant?CorrectIncorrect
Arrange the following soil descriptions on a scale from best to worst. These descriptions include the 5 ‘classes’ we discussed in the video:
Disturbed soil, Bacterial soil, Balanced soil, Fungal soil, Highly fungal soil
Compacted, low oxygen, low organic matter (under 2%), low Fungi to Bacteria ratio, high disease potential.
High organic matter 10%+, pH acidic, Fungi to Bacteria ratio of 5:100.
Decent oxygen levels, organic matter above 3%, pH neutral, Fungi to Bacteria ratio of 1:5.
Good oxygen levels, organic matter >5%, pH slightly acidic, Fungi to Bacteria ratio of 2:10.
Adequate oxygen, organic matter >3%, pH slightly alkaline, Fungi to Bacteria ratio is 0.5:2.
Consider the qualities most plants find appealing in their soils: Do they like to breathe? Do they prefer their soils have ability to retain moisture?
When you sample, at which depth do we generally recommend for biological testing?CorrectIncorrect
