J. O. Klemmedson; R. B. Ferguson Soil Science Society of America Journal 1969. doi:10.2136/sssaj1969.03615995003300060044x
Other claims from this paper (8)
- Intervention effect Shoot and root weights were greater in surface-soil seedlings without added N than in seedlings from lower soil layers.
- Intervention effect Added N reduced seedling yields on surface soils.
- Intervention effect Added N increased seedling yields on the 40-90 cm soil layer.
- Intervention effect A high moisture regime diminished the adverse effects of added N on seedlings grown in surface-layer soil.
- Intervention effect A high moisture regime improved the effectiveness of added N on seedlings in lower-layer soils.
- Observation Six granitic soils were deficient in nitrogen for barley.
- Intervention effect Bitterbrush responded negatively or not at all to added N on the same soils.
- Association Bitterbrush yields declined when plant N reached about 2.0 percent.
