Question

Quizplus · Accepted Answer

Mycorrhizal fungi are particularly efficient at supplying phosphorous to their plant partners, as phosphorous is often found in soil in forms that are not easily absorbed by plants alone. While nitrogen is also an important mineral, mycorrhizal fungi do not always supply it to their plant partners as readily as they do phosphorous. Potassium, magnesium, and calcium are also important minerals, but they are generally more readily available to plants in soil and are less dependent on mycorrhizal fungi for supply.
