Precipitation of dissolved phosphorus from the agricultural ditches

Actor: Turku University of Applied Sciences   ●   Year: 2012   ●   Address: Nautelantie, Lieto, Finland

In the Active Wetlands project (Interreg IVA) ferric sulphate was applied to agricultural field ditches for boosting the retention of dissolved phosphorus. During 2010-2012 the phosphorus dicharges from field ditches were reduced by over 50%.© Turun ammattikorkeakoulu


The action reduced the phosphorus directly available for biological utilization by algae both in the ditch and in the receiving waterway. The study increased the knowledge of applicability of this kind of method in reducing phosphorus loading to the waters. 


The action was carried out within a research, development and awareness raising co-operation project in Estonia and Finland. The method is not included in the mandatory measures of the agri-environmental aid, but has interested water protection associations and private farmers.
