Explore the biological concepts represented throughout Greenfield's supplied educational material.
Bacteria, fungi, protozoa, beneficial nematodes, earthworms, organic matter, water and minerals are shown as an interconnected soil food web.
Root exudates, microbial response, nutrient exchange and root uptake interact around the root zone.
Plant residue → microbial decomposition → nutrient release → root uptake → plant growth → residue returns.
The supplied educational material presents Azotobacter in biological nitrogen fixation and plant nutrition.
Locked nutrients → microbial action → available nutrients → root uptake.
Microbiology is connected to root development, water access, nutrient uptake and plant performance.
