Peterjohn_et_al_1996-N_Saturation_Symptoms

1) high relative rates of net nitrification

2) long-term increases in streamwater concentrations of nitrate and base cations

3) relatively high nitrate concentrations in solution losses

4) little seasonal variability in stream-water nitrate concentrations - with N no longer being limiting in a system, high concentrations of N are expected regardless of the season.

5) a high discharge of nitrate from a young aggrading forest

6) a rapid increase in nitrate loss following fertilization of a young aggrading forest

7) low retention of inorganic nitrogen when
compared with other forested sites. - This was discussed in lecture; N saturation doesn't necessarily imply a ceasing of inorganic N uptake, only a reduction in rate.
