Other claims from this paper (8)
- Mechanism Anion immobilization can prevent cation leaching in forest soil.
- Mechanism Soil acidification requires acid inputs to exceed buffering and weathering to fail to replace leached cations.
- Observation Moderately acid soils with low cation exchange capacity are considered most sensitive to change.
- Observation Very acid and neutral highly buffered soils are considered insensitive to acid rain acidification.
- Mechanism At extremely high inputs, acid rain may increase nitrogen mineralization, nitrification, and soil aluminum mobilization.
- Mechanism Increased nitrogen availability can temporarily increase growth in nitrogen deficient forests.
- Observation Acid rain inputs sufficient to cause acute forest growth responses are apparently rare under ambient field conditions.
- Association Long term effects on forest nutrient status may be beneficial or adverse depending on site nutrients, management, and atmospheric inputs.
