Other claims from this paper (7)
- Intervention effect In both soils, ammonium as the N source lowered soil pH relative to nitrate.
- Intervention effect Mycorrhizal (VAM) inoculation did not enhance the ammonium-versus-nitrate difference in soil pH.
- Intervention effect P depletion extended up to 20 mm from the root surface in mycorrhizal inoculated soil, compared with up to 10 mm in non-VAM inoculated soil.
- Intervention effect In mycorrhizal inoculated soils, the 0–5 mm soil zone contributed more to P uptake than the core soil.
- Mechanism The greater contribution of the 0–5 mm zone reflects a hyphal contribution to P supply.
- Intervention effect Nitrogen applications that caused acidification increased P uptake, attributed to increased demand.
- Association The magnitude of liberated acid or base depended on the form and rate of nitrogen and soil type.
