It is very important for the football field to maintain long-term good conditions for athletes to use in maintenance and management. In addition to daily watering, fertilizing, clipping, and pest control, there is an “renewal operationâ€.
Due to the pressure of the athletes on the soccer field and the mechanical operation, the surface layer of the soil is about 10 cm thick. The surface layer of the soil will produce many changes in the soil. The most obvious is the increase of the soil solid fraction and the reduction of the gas phase rate, which greatly affects the grass. The growth of seedlings.
Increased hardness of the soil, limited growth of grass roots, increased turf breakage, athletes' movements, and increased risk of injury to athletes.
Soil surface boarding, soil permeability is reduced, the penetration effect of fertilizers, pharmaceuticals can not be achieved, reducing the effect of use, while maintaining water capacity, reduced drought resistance.
Soil knotting on the soil surface reduces the ventilation of the soil, resulting in poor gas exchange, poor oxygen supply, and reduced organic matter and fertilizer decomposition rates.
Therefore, the renewal operation of the natural turf football field should be considered from a long-term perspective. Generally, short-term and long-term mandatory operations can be combined. The site update operation time can be shown in the table below.
