Fertilizers contain essential nutrients like phosphorous and nitrogen that help grow healthy plants. However just like humans, plants can only absorb so many nutrients at a time causing the excess nutrients to remain unused in the soil. When fertilizer is over-applied to any landscape it is often washed into our waterways during storms via stormwater runoff. The nutrient rich stormwater enters our waterways like Lake Champlain untreated and if levels reach excess amounts can cause blue-green algae blooms or other water quality issues.
