Phosphorus Removal by Plant Harvesting on Lake Minnetonka <br />John M. Barten, Three Rivers Park District <br />October 22, 2004 <br />also likely due to plant species differences. The two samples containing more than 50% <br />coontail had an average phosphorus percent of 0.39% (dry weight). Conversely, samples <br />containing mainly narrow leaf pondweed were 0.15 % phosphorus (dry weight). <br />Table 1.
