Sports surfaces roulette

Do you want to know what Ruleado de sports surfaces? There are many different types of curlers for sports surfaces, although all of them should have rounded edges to avoid damage and range from 300 - 2000 lbs (135-900 kg) in weight, which is equivalent to 3-15 lbs psi (0.21 - 1.05 kg/cm2) applied to the surface.

Especially in our sports grounds maintenance industry the recommended range is 135 - 450 kg, resulting in 0.21 - 0.49 kg/cm2 of pressure being applied. In native soils, 900 kgs should not be reached (Minner 2005).

Lighter rollers are recommended for general maintenance purposes and heavier rollers for new construction.

We also have to take into account their dimensions. Thus, a roller with a diameter of 400 mm x 600 mm in length and a mass of 500 kg (300 cm2 of base area) will exert a pressure of 1.67 kg/cm2, while another two-unit roller with dimensions of 500 mm x 500 mm and 8 Tm (6000 cm2 of base area) will exert 1.33 kg/cm2, i.e. it will offer less compaction.

The load that occurs in the soil profile dissipates with depth and depends on their texture.

The benefits of roulette are the achievement of higher levelling and improvement of small undulations, firmness, increased rolling speed, increased ball bounce, increased seedling-seed-substrate contact in establishment, reduction of diseases such as dollar spot when removing glutation water or dew (University of Michigan)

Numerous studies show that roulette triggers an increase in the speed of the greens, or in other words, an increase in rolling distance.

However, this effect is relatively short, estimated at around 48 hours, and requires constant use to maintain the increased rolling. Recent studies by the University of Carolina indicate that greens that have been turfed 4 to 7 times had lower quality than greens turfed only once a week, possibly due to a decrease in quality due to a decrease in density from aggressive turfing. The University of Nebraska and the University of Michigan indicate that a 12 inch increase in roll is required to be noticeable to the golfer.

On the other hand, the disadvantages of poorly planned routing are the possible loss of density due to compaction if it is carried out excessively, especially on wet or frozen soils. It is also not recommended to carry out this work on very dry soils or on dormant varieties: only on soils with active growth.

We advise never to rule on surfaces with infectious diseases such as pythium o rhizoctonia.
