Manipulation

IN 1985 Lake N2 was divided with a plastic curtain. During 1985-90 the west half (N2F) was fertilized with approximately 5 times its normal loading of nitrogen and phosphorus using ammonium nitrate and phosphoric acid. The recovery of N2F and the reference side (N2R) are still being monitored.
