Sand topdressing helps control/dilute organic matter accumulation on putting greens. The popularity of high shoot density creeping bentgrass (ex. Penn “A4”, Alpha, etc.) and bermudagrass ultradwarf (ex. Tifeagle) varieties make the incorporation of topdressing into greens difficult. The inability to incorporate can result in much of the topdressing being removed by mowing. Additionally, mower blades loose their sharpness resulting in poor mowing quality.
Article by: Pamela Sherratt With the beginning of spring it's time to start planning season fertilizer programs! Important tasks carried out now in preparation for the season ahead may include a soil test. Conducting a spring soil test provides a historical record of the soil pH and soil nutrient status. This supplies information on how well last year’s fertility program provided for the need of the turf. It also provides information that is used to develop your fertility management plan for the current season. Soil pH and soil nutrient analyses are critical.
Calcined clay is a popular soil amendment used on baseball infields for water management and soil conditioning. Clay is heated at a high temperature, about 1500 degrees Fahrenheit to expand the clay forming calcined clay. On baseball fields calcined clay is used to fill in infield depressions caused by cleats and smooth the surface to provide a true baseball bounce, which contributes to the safety of the field. Calcined clay absorbs water that can help dry a field after a rainstorm, and firm the surface.
Creeping bentgrass is considered a weed on athletic fields and lawns. It produces a superb playing surface for golf and it has great recuperative potential, but it’s shallow roots and lack of wear tolerance make it unsuitable for most athletic sports.
Tenacity (mesotrione) is the first herbicide that results in rapid, easy to visualize reductions in weedy perennial grasses, including creeping bentgrass. Best control, according to most research of creeping bentgrass, is achieved if three applications are made on 14-21 day intervals.
