We measured the nutrient stoichiometry of inputs, outputs, retention, storage, and recycling in three seasonally
nitrogen (N)-deficient reservoirs by incorporating watershed mass balances with measur...
Effects of Sodium Polyacrylate and Phytase-Supplemented Diet on Performance and Phosphorus Retention in Chicks
Sodium Polyacrylate Phytase Phosphorus Chick

In-river phosphorus retention alters the quantity and timings of phosphorus delivery to downstream aquatic systems. Many intensive studies of in-river phosphorus retention have been carried out but ge...
Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?

Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient
loading and installing aeration/oxygenation systems. For five eutrophic lakes, three...
Why the phosphorus retention of lakes does not necessarily depend on the oxygen supply to their sediment surface
