Other claims from this paper (8)
- Association Plant nitrogen was strongly affected by interactions with mycorrhizal fungi and soil crusts.
- Intervention effect Disturbance dramatically reduced nitrogen fixation capacity of biological soil crusts.
- Observation Natural δ15N abundance differed between arbuscular mycorrhizal and nonmycorrhizal herbs.
- Observation Some nitrogen transferred from crusts to plants after 15 days.
- Observation Cyanobacteria in crusts fix nitrogen.
- Mechanism Crusts retain nitrogen that would otherwise leach from the system.
- Observation Some crust nitrogen is available to plants.
- Association Plants face nitrogen competition from heterotrophic bacteria in crusts.
