In the gypsum treatment project in the catchment area of The River Vantaanjoki in 2018-2020, gypsum will be spread across a total of 3,500 hectares of agricultural field. The operation will reduce load of nutrients and suspended solids into The River Vantaanjoki and The Gulf of Finland, thus improving the ecological status of water bodies and enhancing their recreational value. Previously, gypsum treatment of agricultural fields has been examined in several research projects and tested extensively in a pilot project in Lieto and Paimio implemented by the SAVE research project funded by a key project of The Ministry of the Environment, as well as The NutriTrade Project funded by The EU Interreg Central Baltic programme.
The River Vantaanjoki gypsum treatment project is carried out by The John Nurminen Foundation, The Water Protection Association of the Vantaa River and Helsinki Region (VHVSY), The University of Helsinki, and The Finnish Environment Institute (SYKE). The project is funded by private donors through The Foundation’s fundraising efforts, as well as The Ministry of the Environment as a part of the measures outlined in The Finnish River Basin Management and Marine Strategy Plans, as well as the “Breakthrough of Circular Economy and Clean Solutions” (”Kiertotalouden läpimurto ja puhtaat ratkaisut käyttöön”) key project. The objective is reducing phosphorus load from agricultural fields as well as water clarification through reduction of suspended solids runoff.
