What You'll Learn
Coring is a golf course maintenance term
During coring, a special machine removes small cores or plugs of sod from the green, creating holes in the turf. These holes allow for better air exchange and promote optimal soil health, leading to stronger roots and improved turf quality. Coring helps to combat common issues on golf courses, such as soil compaction, thatch accumulation, waterlogging, and nutrient deficiencies.
Soil compaction can occur due to foot traffic, equipment use, and the natural settling of the soil over time. This compaction restricts the movement of air, water, and nutrients, hindering healthy root growth. By creating channels through coring, the soil becomes less compacted, and air, water, and nutrients can more easily reach the roots.
The process of coring is often followed by topdressing, where the holes left by the removed cores are filled with sand. This helps to improve drainage and create a firmer surface. While the greens are healing after coring, which can take up to a few weeks, golfers may experience some frustration as the putting quality is temporarily diminished. However, this short-term inconvenience is necessary for the long-term health and performance of the turf.
Coring is an important practice in golf course maintenance, as it ensures the greens are in optimal condition and meets the expectations of golfers and superintendents. It is a vital step in producing dry, firm, and fast greens that are highly desired in the sport.

The process aerates the greens
Coring, also known as aeration or hollow-tining, is a vital process in golf course maintenance. It involves using a machine or a hollow tine to extract small cores or plugs of sod and soil from the turf of golf greens. This process is essential for the long-term health of the turf and the overall maintenance of the course.
The process of coring aerates the greens by creating channels for better air exchange. Aeration increases the percentage of air in the soil, promoting healthy root growth and allowing for the release of unwanted gases. It helps combat common issues such as soil compaction, thatch accumulation, waterlogging, and nutrient deficiencies. By improving soil aeration, coring ensures stronger roots and improved turf quality.
The TORO ProCore 864 and ProCore 648 are innovative aeration machines that can create consistent round holes without damaging the turf or freshly aerated holes. These machines feature technology that keeps the tines vertical as they penetrate the ground, preventing turf lift and maintaining a level surface.
Coring is typically done once or twice a year, with some recommending hollow tining in the spring and autumn to maintain turf quality during the playing season. While the process may cause temporary frustration for golfers due to the time needed for healing, it is necessary for the overall health and performance of the greens.
By aerating the greens, coring improves water infiltration and oxygen levels, resulting in tighter and healthier plants. This allows for dry, firm, and fast greens, which are desirable conditions for golfers and superintendents alike.

It involves removing small cores from the soil
Coring is a golf course maintenance procedure that involves removing small cores or plugs of sod from the green using a special machine. This process is also known as aeration, aerification, or hollow tining. It is typically performed once or twice a year and is crucial for the long-term health and maintenance of the golf course.
By removing these small cores, coring creates channels in the soil that improve air exchange and promote optimal soil health. This, in turn, leads to stronger roots and enhanced turf quality. Coring helps address issues such as soil compaction, thatch accumulation, waterlogging, and nutrient deficiencies. Soil compaction, caused by foot traffic, equipment use, and natural soil settling, restricts the movement of air, water, and nutrients, hindering the growth of healthy roots.
The cores removed during the coring process are typically about half an inch in diameter, although smaller pencil-sized cores can also be used. The frequency and extent of coring can vary depending on the specific needs of the golf course. The standard recommendation for core aeration is to remove 15% to 20% of the surface area each year, with a sand topdressing of 12 to 15 mm.
Following the coring process, the holes left behind are filled with sand. This step is crucial for healing the greens and promoting healthier plant growth. The process of filling the holes with sand is known as topdressing, which helps dilute the layer of thatch and improves soil quality and drainage. It takes about two to three weeks for the greens to fully heal after being cored, but the long-term gain is healthier turf.
Coring is an essential practice for any golf course superintendent or greenkeeper aiming to maintain championship-level conditions. While it may cause temporary frustration for golfers due to the healing period, the process is necessary for achieving dry, firm, and fast greens, which are highly desired in the game.

It helps combat soil compaction
Coring is a golf course maintenance process that helps combat soil compaction. It involves extracting small cores or plugs of sod from the green, which relieves soil compaction and increases soil oxygen levels. This process is typically done once or twice a year, depending on the soil type and the level of traffic from vehicles or pedestrians. It is important to note that the depth of tine penetration is critical in determining the volume of soil exposed, and the recovery period can range from three to four weeks.
Soil compaction can be caused by vehicular and foot traffic, as well as the natural settling of the soil. This leads to a decrease in total pore space, a reduction in soil oxygen content, and hindered root growth. By removing small plugs of turf and soil, coring creates channels that improve air exchange and promote healthier root systems.
Coring is an effective way to manage soil compaction and improve overall turf quality. It helps alleviate compaction by physically removing small cores of compacted soil, creating space for roots to grow and improving air and water movement. This process also helps alleviate issues related to soil compaction, such as decreased pore space, reduced water infiltration, and increased water retention.
Additionally, coring can be combined with other management practices to further combat soil compaction. For example, greenkeepers may select compaction-tolerant turfgrass species, regulate traffic through various practices, and address thatch accumulation, which is often associated with soil compaction. By combining coring with other management strategies, greenkeepers can effectively enhance the health and sustainability of their greens.

It is also known as hollow-tining
Coring is a golf course maintenance term for the process of aerating greens and fairways. Coring, also known as hollow-tining, involves removing small plugs or cores of turf from the surface. These cores are about 13-16mm in diameter and of varying depths. The process creates channels in the ground, improving air exchange and promoting healthy root growth. It also helps combat soil compaction, thatch accumulation, waterlogging, and nutrient deficiencies.
Hollow-tining is usually carried out once or twice a year, during quieter playing seasons, to minimise disruption. It is typically done outside of the main playing season, often in early autumn, and ideally before wet and cold weather sets in. This gives the turf time to grow and the holes time to seal.
The process can be done using various methods and machines. One method involves using a solid tine, a piece of cylindrical metal attached to a machine, that punches into the soil and makes a hole. Another method is micro-tining, which uses needle-like tines to produce lots of holes with minimal disruption.
Following hollow-tining, sand top dressing is applied to fill the holes and improve soil structure. This step is crucial for the swift recovery of the greens, improving drainage and oxygen flow to the roots.
While the process may seem detrimental to the quality of the greens, it is necessary for the long-term health and maintenance of the course. It ensures the greens remain in peak condition, ready to challenge golfers and provide a superior golfing experience.
