On a plantation established in 2004 from stem cuttings at a density of 20,000 trees per hectare, we investigated growth and nutritional plant response to a high hydraulic regime for two species (Salix viminalis and Populus nigra×Populus maximowiczii), using a comparative approach with measurements from irrigated and control plots. The plantation was irrigated from June to September 2005 with about...
The high concentrations of phosphorus and suspended matter in freshwater aquaculture are often an environmental concern and given the difficulties for sample preservation, an in situ monitoring tool would be most useful. The diffusive gradients in thin-films (DGT) technique can be used for on site monitoring and also has the advantage to integrate measurements over time and thus partly record ephemeral...
The DGT technique has potential as a tool for monitoring reactive phosphorus in freshwater aquaculture effluents. Because those waters have high concentrations of suspended matter and nutrients, biofilms may form on the surface of the DGT devices. Those biofilms may hinder the movement of reactive phosphorus and hence interfere with the DGT measurements. We tested two antibiotics, glutaraldehyde and...
