Issue

Eutrophication

Insufficient water quality due to a nutrient overkill.

Low iron content in the soil compared to the phosphorus content has caused the soil to discharge too much phosphorus into the water column. This leads to eutrophication and algal bloom.

Solution

Iron supplementation peat-bog lakes

The iron content of the soil is supplemented until the iron-phosphorus balance is restored.
