Phosphorus in the Minnesota River

This booklet discusses phophorus pollution of the Minnesota River. Designed for use by the general public, it provides basic information on current phosphorus levels, point and nonpoint pollution sources, and various ongoing efforts to respond to the problem.

Evaluation of Potamogeton pectinatus as a tool for phosphorus removal

Ribikawskis, Matthew J
This study examined the potential of transplanted Potamogeton pectinatus (sago pondweed) to be used as an effective tool to remove phosphorus from a hypereutrophic lake. Field studies showed growing P. pectinatus from tubers in-lab and then transplanting into enclosed structures within Crystal Lake, Minnesota, promoted positive plant growth and phosphorus uptake. While planted within Crystal Lake, mean increases per plant were found in shoot length (11.21 mm SE±15.70), in root length (89.95 mm SE± 16.20), and in total dry weight (0.45 g SE±0.11).
