Playing Conditions of Grass Sports Fields: A Soil Technical Approach1

The top layer of soil must be strong if grass sports fields are to maintain good playing conditions under the forces exerted when soccer is played. Changes in soil strength, resulting from changing bulk density and soil moisture conditions, can be registered by measuring the penetration resistance. From field investigations the penetration resistance was found to be a measurable and reproduceable criterion of the playing conditions.
In laboratory experiments we investigated the response of medium-fine sand with increasing organic matter content to compactive loadings and soil moisture conditions similar to those that occur under field conditions. A more exact examination in the laboratory of the effect of soil water pressure heads on penetration resistance at different bulk densities of the same sand was made over the range of heads existing during the most vulnerable period of the playing season.
It appeared that the contribution of grass to soil strength depends upon the type of root zone material. The more essential the contribution of the grass to the soil strength, the more the playing frequency must be limited. Finally, a short outline of the method conceived to establish the playing conditions at a certain bulk density of the top layer resulting from a number of physical factors is given.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
