Fertilizer: Why Is It Harmful To The Lake?

 

 

Most people don't know that fertilizers are a major contributor of Phosphorus and Nitrogen in Lake Isle and Lac Ste Anne.  These nutrients promote the growth of Blue-green algae (Cyanobacteria). In fact, 1 lb of phosphorous can produce at least 500 lb of living Blue-green algae.

 

NOW YOU KNOW, WHAT ARE YOU WILLING TO DO ABOUT IT?

 

LILSA's goal is to eliminate all cosmetic fertilizer use around our lakes.  You can help by not using fertilizer on your lawn.  We will also be discussing this goal with various levels of government including the Summer Villages and Parkland and Lac Ste Anne Counties and asking them to ban the use of cosmetic fertilizer around our lakes.
