The effect of traffic on the physical and chemical properties of natural-artificial turfgrass bed

In order to further understand the characteristics of natural-artificial turf, the research is focused on the analysis of the physical and chemical properties of natural-artificial turf after mimic traffic processing, with the control group of natural turf. The result showed that, with the increase of the traffic intensity, the soil compaction and soil pH of every group increased gradually and soil water infiltration rate decreased. Soil electric conductivity decreased at first but then increased. Compared with the control group, soil water infiltration rate of A6 and A8 increased significantly. There was a huge difference of the variation of soil water content between the group with 15 cm turfgrass bed and the one with 5 cm turfgrass bed. The density of artificial turfgrass and the growth of natural turfgrass in the natural-artificial turf have a significant impact on its soil water content. Natural-artificial turf with an appropriate density is beneficial to soil chemical properties. It can not only decrease soil salinity but also stabilize soil acidity or alkalinity.
