VIDEO Phosphorus removal filter boxes for drained agricultural fields
Ghent University and Inagro test filter systems for drainage water in arable fields. An easy to install box with filter substrate at the drainage pipes can reduce the phosphorus (P) losses significantly.
Venner Bruchkanal: Improved P filter system with iron-coated sand is ready
Since the start of the NuReDrain project, the Lower Saxony Chamber of Agriculture developed and constructed a filter shaft to collect and filter water from a drained field before it flows into the receiving water.
In the past months improvements have been made to deal with clogging due to the presence of ochre flocs..
Inagro builds a constructed wetland inspired by examples of Aarhus University
The research institute Inagro obtained new experimental fields for research on arable land and open air horticulture.
Because nitrate losses from drainage water are an important issue in Flanders and based on the experience of NuReDrain partner Aarhus University a constructed wetland has been built to evaluate its performance in local conditions.
