The basis for sound nutrient management and water quality protection programs in turf management revolves around soil testing. A "Basic Soil Test" will typically provide infomation on soil pH and the levels of the macronutrients phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca).
Contact your county or state extension specialist to identify the appropriate testing methods and optimum laboratories in your region.
For more information regarding soil fertility, please visit the Fertility page in the Knowledge Center.

There are three basic types of athletic field rootzones:
Natural soil - soil that exists at the site or topsoil that is transported to the site
Modified soil - existing soil at the site is mixed uniformly with a coarse physical amendment (such as sand)
Soilless medium - a rootzone that is composed entirely of sand
Rootzone composition affects overall field performance, including turfgrass growth, nutrient retention, and water infiltration and percolation. Knowing the makeup of your rootzone can assist in reducing compaction, planning a fertility program, and determining proper irrigation practices.

Soil compaction is the compression of topsoil, primarily due to foot or vehicular traffic. Excessive compaction can prevent the passage of air, water, and nutrients into the soil. Turfgrasses growing on compacted soils generally have shallow root systems and poor density, exhibit stress symptoms more readily, and have reduced recuperative potential.
Compaction management includes various cultivation practices, which are outlined under Aeration/Topdressing of the Knowledge Center.

Drainage is one of the most important issues when managing a sports field. Your field will not perform well if you do not have surface or internal drainage in place. Surface and subsurface drainage problems, such as standing water and high water tables, can pose a safety hazard to athletes and other users. These problems can also cause cancellation or postponement of events due to field closure. It is important to understand what types of drainage will work best for your field to enhance user safety and reduce field closures.
