The chlorophyll and nitrogen levels are highest in the Lagoon during the warm, rainy summer months. This is when the waters are warmest and the most runoff of nitrogen occurs. Martin County has passed a strong fertilizer ordinance that gives lawn owners a fertilizing holiday from June 1st to September 30th. Despite the success, we still face many challenges in passing similar ordinances in other Indian River Lagoon counties. Please help us build more pressure by sharing this quiz with your friends and encouraging others to sign the petition.

When chlorophyll and nitrogen levels are highest in the water it leads to the highest Dolphin deaths in the indian River Lagoon! Curb the dumping of these toxins into our Nations & World Waterways Now & support the Ocean River Institute

Excessive fertilization has had a very detrimental affect on seashores, and rivers and lakes. Is that the only way agriculture can be done? With harmful fertilizers.

The only sprays I use are fully organic ; sulfur and neem oil. These are miraculous as one to 3 sprays/year are the most needed.

why is there always something wrong, so much filthy shit in the water , that has to be stoped.

I feel the animals don't need all that stuff in the kagoon.
