Amending agricultural fields with gypsum has been proposed as a cost-effective measure to reduce P load coastal waters. To study its performance on large scale, we treated 1490 ha of clayey phosphogypsum (4 t ha−1) in southwest Finland and monitored the recipient river online sensors water sampling for preceding spring 5 years after amendment. Gypsum immediately decreased riverine fluxes, effect lasting at least particulate (PP), total suspended solids (TSS) dissolved organic C (DOC) 1–2...
Abstract Eutrophication of the Baltic Sea is driven by phosphorus and nitrogen. While anthropogenic point source loads both nutrients have decreased markedly, further reductions are needed. This true particularly for phosphorus, as highlighted its stringent abatement targets in HELCOM’s Action Plan. To meet targets, more results need to be achieved non-point abatement, specifically from agricultural sources. The growing pressure agriculture may lead environmentally economically inefficient...
We estimated the changes in losses of particulate and dissolved phosphorus (P) after treating 93 ha agriculturalfields with gypsum (4 t ha–1) a 245 catchment southern Finland. Runoff was monitored using onlinesensors manual sampling during one high-flow period before six periods amendment.Turbidity recorded by sensors correlated P analysed laboratory, which enabledthe evaluation from online data. Using covariance model, amendmentwas to have reduced loss 64%. The reactive appeared decreaseby...
Amending agricultural fields with gypsum has been proposed as a cost-effective measure to reduce P load on coastal waters. We treated 1490 ha of clayey phosphogypsum (4 t ha−1) in Southwest Finland and monitored the recipient river online sensors water sampling for preceding spring 5 years after amendment. Gypsum immediately decreased riverine fluxes, effect lasting at least particulate (PP), total suspended solids (TSS), dissolved organic C (DOC) 1–2 reactive (DRP). Compared an upstream...
In Finland, the first large-scale efforts to control nutrient loading from agriculture got under way with introduction of EU Agri-Environmental Program in 1995. We examined whether these have decreased agricultural losses and improved quality receiving waters. To do so we used monitoring data on fluxes nutrients total suspended solids catchments 19902004 water agriculturally loaded rivers, lakes estuaries 19902005. No clear reduction or improvement was detected. Hydrological fluctuations...
