Topic: Stormwater Management Subject: Modify lawn care practices. Even though soil, grass clippings, and leaves are natural materials, they can also hurt local lakes and rivers. Yard waste contributes nutrients, such as nitrogen and phosphorous, which cause unwanted and uncontrolled growth of algae and aquatic weeds. Soil can clog spawning areas for fish. Recycling yard waste reduces the need for fertilizer, reduces lawn maintenance, and is better for the environment. Grasscycling is leaving grass clippings on the lawn to decompose rather than removing them from the site. When you mow regularly, clippings quickly decompose and release nutrients to fertilize the lawn. Composting is another way to utilize both yard and household waste. It takes about 10-20 minutes per week, uses a small amount of yard space and provides us with a opportunity to get rid of something we have so much of (kitchen scraps and yard debris) and create something of greater value (compost). Compost bins and kitchen pails are available through the Marathon County Solid Waste Department. Overuse of fertilizers or pesticides cause stormwater to pick up the chemicals from the soil and carry them directly to lakes and streams. These chemicals can kill aquatic plants and animals. Always follow label instructions and do not overuse! Slow release fertilizers are less likely to be carried into streams than quick-release fertilizers. When possible, use Integrated Pest Management (IPM) practices. IPM uses chemical (pesticide), biologic (natural predators of pests), and organic (compost) materials to control pests. How to care for your lawn in the most environmentally friendly way If you still would rather have grass clippings and other yard waste removed from the site, there are several yardwaste collection sites in the area, or check with your waste hauler for their policy on yard waste removal. Whatever you do, do not dispose of the waste in the storm sewers! Below is a list of local yard waste collection sites:
