Rainfall and runoff chemistry of Florida pine flatwoods

Data on the runoff chemistry of an undisturbed 140 ha pine-cypress flatwoods catchment in Florida were correlated with data on precipitation chemistry. Regression analysis demonstrated a weak correlation between rainfall acidity and nitrate-nitrogen and sulphate-sulphur in runoff. The average volume...

Description
Summary:	Data on the runoff chemistry of an undisturbed 140 ha pine-cypress flatwoods catchment in Florida were correlated with data on precipitation chemistry. Regression analysis demonstrated a weak correlation between rainfall acidity and nitrate-nitrogen and sulphate-sulphur in runoff. The average volume-weighted acidity of monthly runoff was almost 1 pH unit less than that of rainfall and remained consistent over time. Runoff chemistry showed a significant decrease in nitrate-nitrogen and phosphate-phosphorus over time, while calcium showed a significant increase. The ecosystem absorbed most of the hydrogen, nitrogen and phosphorus, with only a slow loss of base elements.
