Carrying out regular soil aeration work is one of the most important types of mechanical maintenance for grass surfaces that are used for sports and are subject to intense use, such as golf courses, football pitches and riding arenas. Continuous working of the soil, also known as “aeration”, is highly important for a number of reasons. Particularly the fact that both the grass roots and the beneficial microorganisms in the root zone require sufficient oxygen for healthy development.

After a certain period of use of these surfaces for sports, the soil will inevitably become compacted. If this compacting has advanced to the stage where not enough water, nutrients and oxygen can penetrate the soil, healthy growth can no longer take place. When the exchange of gases between the soil and the atmosphere is impeded, methane begins to build up. Within this environment, anaerobic bacteria begin to form in the root zone. These microorganisms have a negative effect on root growth.

Consequently, depending on the level of use of the sports grounds, soil aeration must be carried out on a regular basis. In this context, the time at which the aeration occurs and the general manner in which it is carried out depend on several factors, such as the level of moisture in the soil, the soil type or, as mentioned above, the frequency with which the green areas are used. To assist with the implementation of this aeration work, we offer a wide range of aeration tools in various configurations.

Hollow tine

Working with hollow tines allows for ideal aeration, since soil is removed without worsening compaction. This gives rise to tubular hollows, which are then filled with coarse soil, usually hydro classified quartz sand.

Features

removal or reduction of unwanted organic material

removal of soil without edge compression

improvement/restoration of gas exchange in the first 10 cm of the carrier layer

improvement of physical properties of the soil

improvement of pore volume and/or soil compaction

reduction of water storage

reduction of black layer (waterlogged soil)

depending on diameter, the number of holes should be 100 – 500 holes per m²

Additional tasks

clearing or hauling of excavated material

sanding with hydro classified dry quartz sand, for example, in the following quantities: 1L – 5L / m²

Solid tine cross

The cross tine makes a cross-shaped hole on the surface of the green, followed by a cross-shaped hollow, with the aim of opening the grass surface whilst protecting it and reducing edge compression.

Features

cross-shaped rib structure, rib width of between 1.5 mm – 5 mm

aeration without removal of soil

effective water and air flow

minimal edge compression

up to 30 % more peripheral surface (as compared with rounded solid spoon)

no lifting of earth with tool

no suction effect during withdrawal of tool

lawn ready for play immediately

Additional tasks

none

Solid tine round

When aeration is carried out using solid tines round, hollows are created without the removal of soil. Thus, the soil is pushed down and to the sides. The hollows created act as tubes for effective gas exchange.

Features

aeration without removal of soil

effective water and air flow

underground compaction is broken up and loosened

Additional tasks

none

Solid tine flat

During aeration with a flat tine, the tool leaves behind a slit, which ensures ideal water and air flow. The longer blade is attached in the direction of the motion.

Features

aeration without removal of soil

effective water and air flow

underground compaction is broken up and loosened

Additional tasks

none
