We are a research institute that works on natural resource protection, conservation and management. To finalize one of our projects, we want to create a video report about the obtained results. In this video we would like to include an animated process scheme that shows the pathway of phosphorus from agricultural lands through groundwater and drainage ditches to the receiving surface waters. A specific feature in this pathway is a filter that retains phosphorus. Total length of the animation would be around 30 sec.
