A single grass field soil is adapted to the growth, reproduction, and high yield of grass seedlings, which is inconsistent with the most fundamental requirements of football and other sports pastures. In the football field or other sports venues, the requirement for grass bed soil quality is that the grass bed has good air permeability, good water permeability, sufficient nutrients, and the growing grass is green and stable, and the grass bed is stable, for the athlete to exercise and trample on it. It does not lead to dew exposure and injury to the athlete's body. In the event of a rain encounter, no surface water flow will affect the competition.
The composition and arrangement of soil particles determine the physical, chemical and biological properties of the soil. It is closely related to the moisture, air, heat and nutrients needed for plant growth and development. From the classification of soil texture in China, it can be seen that sand is the best, and sand is from fine sand (0.05 to 0.25cm) to coarse sand (0.25~ In the range of 1.0cm), medium sand of 0.25~0.5cm is most suitable for use, so the medium sand content in the grass bed should not be less than 60%, preferably 100% medium sand, different soil quality grass. The effect of the bed can be seen in the different effects of structure allocation in the grass bed. See the table below for the ideal structure of the grass bed.
Different soil quality grass bed structure
Minerals (%) | Organic matter (%) | Water content (%) | Air volume (%) | effect |
45 | 5 | 25 | 25 | Ideal |
50~65 | 5 | 20~25 | 10~20 | It is not easy to knot the soil |
45~60 | 3~5 | 20~30 | 10~20 | Poor soil drainage |
56~75 | 5 | 5~30 | 10~30 | Compact sand |
