GYPREG: Gypsum potential in Sweden and field test preparations

The main purpose of the GYPREG project is to increase the uptake of gypsum treatment in agricultural fields and promote the adoption of good practices to reduce phosphorus losses into the Baltic Sea. Together with Swedish University of Agricultural Sciences (SLU), RFTB performed a GIS-analysis (Geographic Information System) of agricultural areas in Sweden draining to the Baltic Sea and suitable for gypsum amendment. The study showed that there are 229 645 hectares of suitable land in Sweden draining to the Baltic Sea, where gypsum treatment can be applied.
