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...
Two experiments were conducted to evaluate the effects of addition of sodium polyacrylate (SPA) to a phytase-supplemented diet on the performance and phosphorus (P) retention of chicks. In experiment ...
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...
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...
In order to improve the trophic state of Lake Sempach, a eutrophied lake in central Switzerland, its external phosphorus (P) load has been decreased and its hypolimnion has been artificially oxygenate...
