Calculations of percent nutrient removal were made assuming rooting zone depths of 15 cm for the rush and maidencane, and 30 cm for the cattail. It was also
assumed that the total available nutrients were the sum of 26 applications of the solution for the thickness of this root zone.
∗∗
Where calculations result in percentages greater than 100, natural mixing of the nutrients within the tank would have provided nutrients in addition to those
calculated just for the root zone thickness.
