Phosphorus is a crucial nutrient for the aquatic environment, however its excess has brought imbalance to the lake ecosystem. The mobile forms of phosphorus in the sediment are the available fractions that will be ...

Under no-tillage field conditions, cover crop (CC) residues remain on the soil surface and decompose at a slow rate. We used three CC species (oat, Avena sativa L.; rye, Secale cereale L.; and ryegrass, Lolium multiflorum ...

The present research aimed to investigate the stability of pellets and phosphorus leaching of diets formulated for juveniles of Nile tilapia (Oreochromis niloticus), with different sources of phosphorus and different ...

Integrated multitrophic aquaculture (IMTA) systems are designed mainly for efficient use of resources. Substrates added to aquaculture ponds provide space for periphyton to settle and recover nutrients, making these nutrients ...

The mechanisms which controls the fixation and/or release of P in sediment of an extremely acidic lake (pH = 2.0 to 3.0) and its response to the influence of eutrophic urban waste water were investigated. The results, in ...

Three experiments were conducted to evaluate corn distillers' dried grains with soluble (DDGS) digestibility and the effects of soybean meal replacement by corn DDGS in diets for P. mesopotamicus on growth performance, ...

Phosphorous (P) is a limiting nutrient of algal growth. Reducing input of point P sources of surface waters, although essential, is not enough towards mitigating eutrophication due to the P internal loading. There are ...
