摘要：

Fertilization of a swale plant community with various levels and combinations of nitrogen, phosphorus and potassium resulted in increased plant growth. Nitrogen addition produced the greatest increase in biomass. At some high nitrogen levels, phosphorus limited plant production. Potassium fertilization did not influence plant growth. Phosphorus fertilization decreased the levels of soil calcium, magnesium and manganese. A shore-perpendicular gradient in apparent saltwater inundation influenced soil pH and the concentrations of iron, phosphorus, and magnesium. © 1990 Annals of Botany Company.
