Nine common species of aquatic macrophytes took all their phosphorus from the sediments when grown in situ in both a mesotrophic and a mildly eutrophic bay. Even under hypertrophic conditions, the sediments contributed an average of 72 percent of all the phosphorus taken up during growth. These experiments unambiguously demonstrate for the first time that submergent macrophytes in nature over-whelmingly depend on the sediments for their phosphorus supply and characterize them as potential nutrient pumps to the open water.
在中营养和轻度富营养的湾中，原位生长的九种常见水生植物均从沉积物中吸收所有的磷。即使在富营养条件下，沉积物在植物生长过程中提供的磷平均也占总吸收量的 72%。这些实验首次明确地证明，自然界中的沉水植物极大地依赖沉积物来提供磷，并将其描述为潜在的营养物向开阔水域的泵。
