The Impact Of Reduced Golf Course Maintenance / El impacto del mantenimiento reducido del campo de golf

Steve Kammerer, Ph. D., regional director, Southeast Region

While golf courses may not be deemed essential businesses during these troubled times, failing to perform some level of golf course maintenance can cause serious damage to the course and leave a long and expensive road to recovery. In the Southeast, grass is actively growing throughout the year. Especially now, with bermudagrass waking from its winter slumber with a flourish of growth. If basic maintenance tasks, like the ones listed below, are not performed then costly problems will follow.

Si bien los campos de golf no pueden considerarse negocios esenciales durante estos tiempos difíciles, no realizar algún nivel de mantenimiento del campo de golf puede causar daños graves al campo y dejar un camino largo y costoso para la recuperación. En el sureste, la hierba crece activamente durante todo el año. Especialmente ahora, con bermudagrass despertando de su sueño invernal creciendo con fuerza. Si no se realizan tareas de mantenimiento básicas, como las que se enumeran a continuación, seguirán costosos problemas.

Scouting

General daily scouting is necessary to identify and address the many problem areas that are constantly emerging on a golf course. Sprinkler head issues or irrigation breaks, left unheeded, can cause significant long-term damage. Outbreaks of many different insect pests can occur suddenly and require localized insecticide applications to prevent damage. Scouting reduces the potential for turfgrass loss as well as the need for unnecessary applications of pesticides, fertilizers and other products.

Reconocimiento

La exploración general diaria es necesaria para identificar y abordar las muchas áreas problemáticas que están surgiendo constantemente en un campo de golf. Los problemas con los aspersores o las averías de riego, si no se atienden, pueden causar daños significativos a largo plazo. Los brotes de muchas plagas de insectos diferentes pueden ocurrir repentinamente y requieren aplicaciones localizadas de insecticidas para evitar daños. El reconocimiento reduce el potencial de pérdida de césped, así como la necesidad de aplicaciones innecesarias de pesticidas, fertilizantes y otros productos.

Mowing

Turfgrass must continually be mowed and cared for, especially on putting greens. The grasses on greens are usually different than what is growing on the tees, fairways and roughs. These varieties were bred and developed for their ability to withstand low daily mowing. The general rule of thumb in mowing any turfgrass species is to never remove more than one third of the leaf blade in a single mow. If a golf course is shut down with no maintenance activities for two to four weeks or more, the first mowing will undoubtedly lead to scalping of the playing surface and turfgrass loss. Putting surfaces may need to be regrassed if allowed to grow, with no mowing, for too long.

Cultivation

Aeration, venting and vertical mowing with routine sand topdressing is important to maintain soil porosity for gas exchange and water percolation. Many courses with active turfgrass growth on the putting greens perform these activities every week or every other week. When they are not performed on a scheduled, recurring basis, organic matter accumulates in the soil profile – negatively impacting rooting, turf density and surface firmness.

Pests

Weeds that normally are controlled through mowing will gain an upper hand when grass is not mowed. Mowing is the most effective prevention against weeds in turfgrass. With very few herbicides labeled and legal for emerged weed control on putting greens, weeds left to seed can produce an exponential increase in weed pressure causing problems for many years to come. Diseases will also become more problematic when carefully maintained turf is allowed to become thick, unmown, matted grass. Many of these diseases, left unchecked or untreated with fungicide, have the potential to kill large swaths of even the best turf.

Plagas

Las malas hierbas que normalmente se controlan a través del corte ganarán ventaja cuando no se corte el césped. Cortar el césped es la prevención más efectiva contra las malas hierbas en el césped. Con muy pocos herbicidas etiquetados y legales para el control emergente de la maleza en los campos, las malas hierbas dejadas para semillar pueden producir un aumento exponencial en la presión causando problemas durante muchos años. Las enfermedades también se volverán más problemáticas cuando se permita que el césped cuidadosamente mantenido se convierta en hierba espesa, sin cortar y enmarañada. Muchas de estas enfermedades, si no se controlan o no se tratan con fungicidas, tienen el potencial de matar grandes extensiones incluso del mejor césped.

Nutrition

Putting greens receive regular applications of fertilizer. These nutrients are commonly applied with low doses of growth regulators to produce a subdued but steady growth rate. If these applications are not made on a regular basis, turf quality will deteriorate and eventually require aggressive maintenance practices for recovery.
