Some Physical Aspects of Sports Turfs
- P. Boekel
The playability of turf for football and field hockey in autumn is a very important property. This is especially true in countries like The Netherlands where rainfall exceeds evapotranspiration, resulting in a wet, unstable top layer. To find how such situations can be improved, turfs around Groningen, The Netherlands, were investigated for topsoil stability, groundwater table, soil humus, clay content, and bulk density.
By graphical and numerical analyses of the results it was found that the stability increased as the bulk density and depth of the groundwater increased. An interaction between the effects of these two factors was found, indicating that the effect of bulk density became smaller as the groundwater depth increased. For maintenance it is important to know how to control the bulk density. This can be done by changing the content of humus, clay, and sand or by changing the arrangement of soil particles through compaction. An indication of the acceptable humus content in combination with the density of the topsoil for situations varying in depth of the groundwater table is given.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
