1. Determine what’s required

Each sport has important playing characteristics and requires specific turfgrass and/or soil conditions as they would affect the sporting event. For example, consider the grass cutting height. If the field is used primarily for field hockey or soccer, it may require a lower cutting height to promote faster ball roll versus a football field, which may be maintained at a higher cutting height. Also, keep in mind that when one selects a lower growing, faster playing surface, there likely is going to be a need for more specialized mowing equipment and a significant increase in mowing frequency.

Assess the field’s crown (i.e. slope) and surface uniformity. The crown assists with surface drainage of water to prevent standing water and wet, muddy, unsafe playing conditions. Ensuring a smooth, uniform playing surface can eliminate low areas and divots in the field which could potentially collect water or present a tripping hazard to users.

2. Adjust your strategy

All athletes deserve a safe field, but evaluate who is using the field and how it’s being used. Is it a practice field, for youth recreation, or for sanctioned league play? Game fields typically top the priority list when it comes to maintenance and resource allocation, but all fields should be safe for use. Excessive use is another factor in a field’s playing condition. Managing practices and the rotation of goal locations (soccer, lacrosse, field hockey) is an essential part of the field management strategy. These issues should be discussed with the staff prior to the use of the field. In times of stress, worn areas are often the most likely to present issues. For example, during rainy conditions, worn areas can collect and hold water. During drought stress, these spaces can become, hard, compacted and uneven.

Keep an eye on the weather. Continuous play on a field experiencing stress from extended drought can cause irreversible damage to turfgrass and soil conditions.

3. Consider climate change

The varying sports will almost always lead to variability in field playing conditions, depending on growing conditions for the grass. Turfgrasses are categorized as warm-season or cool-season depending on how well adapted they are to various climates. Each location’s climate plays a large role in determining the type of grass, when and what field maintenance activities take place, irrigation needs and field use.

For example, a field in New York will typically be planted with a cool-season grass. Field maintenance generally takes place April through November depending on snowfall. Irrigation is usually only needed during the hot summer months and surfaces are used in the spring, summer, and fall. By comparison, a field in Florida will be planted with a warm-season grass. Field maintenance and irrigation may take place at anytime of year and typically fields are available for use almost year round.

4. Assess soil conditions

The majority of sports are played on native soil (or subsoil) and they require regular chemical testing by a certified lab to determine pH and nutrient levels. Soil test results provide the information needed to apply the correct amount of nutrients. Implementing the correct maintenance practices – irrigation, fertilization, aerification, topdressing – can deliver optimal growing conditions for the turfgrass of choice. There are private labs and local extension offices that can assist you in conducting a meaningful soil test and interpret the results.

5. Identify key equipment

A mower is the first piece of equipment identified in natural grass field management. Evaluate your budget and the accessibility of other equipment – such as soil aeration equipment, spreaders and/or sprayers – and the variety of hand tools required for the detail work. If an equipment purchase isn’t feasible, consider contracting out services, such as aeration. Other options include renting equipment or sharing with nearby facilities.

There are many benefits to the players, sporting activities and environment in playing sports on properly maintained natural grass fields. However, one point is very clear about managing natural grass fields – someone, or a particular group, has to take ownership of the management of the surface.
