| What is the role of iron as a limiting nutrient and affecting nitrogen fixation and carbon sequestration in large areas of the Southern Ocean? |
| Sources of immobilized nutrients during decomposition include translocation from soil or litter via fungal hyphae, throughfall, and nitrogen fixation. |
| In return, the plant shelters and nourishes the bacterium inside root nodules, where nitrogen fixation occurs. |
| Thus, we can see that nitrogen fixation is a unique process in which the soybean plant and bacteria work closely together throughout the season. |
| One study has also shown that glyphosate applications on RR soybeans may depress soybean root nodulation and therefore nitrogen fixation. |
| This nitrogen fixation still requires intense respiration, which depends on the oxygen permeability of the nodules. |
