Researchers from Tokyo Metropolitan University have studied how polymer-coated fertilizer (PCF) applied to fields ends up on beaches and in the sea. They studied PCF deposits on beaches around Japan, finding that only 0.2% of used PCFs are washed into rivers and returned to the coastline. When there are canals connecting fields to the sea, this rises to 28%.
