Protozoa and plant growth: the microbial loop in soil revisited

Protozoa and plant growth: the microbial loop in soil revisited (NOT OPEN ACCESS)

SUMMARY: This is an in-depth review on the rhizosphere and the interactions between protozoa, nematodes, and plant roots.

LESSON COMMENTS: This can be read like a textbook for students. Alternatively, teachers can assign relevant sections. The rhizosphere can be created and observed in a petri dish (see pictures in section III). This small ecosystem near the roots of plants and its role in an ecosystem have greater implications when it comes to agriculture, fertilizers, nitrogen and carbon use by plants, and even how pollutants can change the interactions between the microorganisms.
