Suppliers > Field and Grounds Maintenance

Maintaining the quality and safety of a professional sports playing field and outdoor areas is an important element of facility operations. Upkeep of these landscapes can require significant amounts of water, fertilizer, and pest control. Pesticides and fertilizers can cause a variety of harmful impacts on public health and the environment.

However, there are many ways to reduce outdoor water use and find alternatives to harmful products. For more information about water-efficient landscaping, visit the Landscaping section of this guide. Consider consulting with your organization’s suppliers to determine if there are more water-efficient and less toxic alternatives to the products that you are currently using on your field.

Reducing your organization’s use of pesticides and fertilizers can also save money. Consider adopting the principles of integrated pest management (IPM) outlined below, to prevent infestations before they start.

Reducing pesticides and fertilizers can save money

It is possible to have healthy, great-looking plants and grass while minimizing the use of harmful pesticides and fertilizers. Minimizing the use of these chemicals means that your organization doesn’t need to purchase them as often, saving you time and money.

Many schools across the country have adopted integrated pest management (IPM) techniques to reduce child exposure to harmful pesticides. In Montgomery County, Maryland, for example, the school district reduced the number of pesticide applications from 5,000 in 1985 to zero in 1989 using IPM techniques. This reduction yielded an annual savings of $1800 per school. Monroe County schools in Indiana reduced their pest management costs by over $13,000 per year through IPM. Case Studies

Integrated Pest Management

Integrated Pest Management (IPM) is an approach to pest management that incorporates aspects of a facility’s operation to help reduce the need for pesticides. IPM means preventing infestations before they start, and using pesticides only when necessary. There are various approaches that your organization can adopt to decrease its reliance on chemical-based pest control. Consider the steps below, and consult the additional resources at the end of this section for more information.

  • Use native plants, trees, and grasses
  • Fill cracks in walls and pavement
  • Keep vegetation at least 1 foot away from structures
  • Clean food-contaminated dishes right away
  • Clean garbage cans often
  • Keep compost bins properly maintained

Consult the resources below for more information on IPM. Though many of the guides below are aimed at schools, the principles can be applied to other buildings and businesses.

Pesticide product specifications

There is a wide range of pesticide chemicals, and most of them are potentially harmful to public health and the environment. The best strategy is to reduce the amount of pesticides your organization uses. Still, there are some pesticides that are less harmful than others. Consider avoiding pesticides that are classified as carcinogens, reproductive or developmental toxins, endocrine disruptors, or neurotoxins.

EPA categorizes pesticide products by toxicity on a scale of I – IV, with the lowest numerals indicating the most toxic products. Consider buying products that are categorized as III or IV, and avoid those that are categorized as I or II. Categories III and IV are labeled with the word “Caution”, while Category II products carry the label “Warning”, and Category I products are labeled “Danger”.

Fertilizers

Consider consulting with your organization’s current suppliers to determine if there are less harmful alternatives to the fertilizer products that you are currently using.

Minimizing the use of fertilizers is also important and can save your organization money. Review the tips and resources below to learn more about reducing your organization’s use of fertilizer.

Fertilizer use reduction tips

  • Plant native vegetation species
  • Use compost instead of chemical fertilizers
  • Plant low-maintenance vegetation
  • Do not use more fertilizer than is recommended on the label
  • Consult with your suppliers and groundskeepers concerning grass mixtures and plants that will thrive in your area with minimal fertilizer

Environmental Benefits

Pesticides and fertilizers can harm public health and the environment. Many pesticides contain potentially toxic chemicals that can cause negative health effects such as cancer and neurological and reproductive disorders. In addition, pesticides can migrate into lakes and streams as they are swept away when it rains. Fertilizers contain phosphorous and nitrogen compounds, important nutrients that aid plant growth. Unfortunately, too much of these compounds is a bad thing, especially in aquatic environments. When aquatic environments are loaded with nitrogen and phosphorous, algae in the water grows at a rapid pace. When this algae decomposes, it causes a significant drop in oxygen concentrations, killing fish and other aquatic organisms. This process is called eutrophication. By reducing your organization’s use of pesticides and fertilizers, and by buying less toxic products, you help to reduce these risks.
