Abstract/Contents:"The playability in autumn and winter is a very important property of turfs in use for scoccer [soccer] and hockey. This is especially true in countries as the Netherlands where in that period rainfall exceeds evaporation, often resulting in a wet and unstable top layer. How can such situations be avoided or corrected? To be able to answer this question the factors affecting top layer stability and their quantitative effect must be known. We made the following observations and measurements on a great number of turfs in and around the city of Groningen: a. the stability of the top layer, frequently estimated by the so called 'heel method', but also occasionally measured by other methods, b. factors which were expected to affect the stability of the topsoil, namely, depth of the groundwater table, humus and clay content, bulk density and turf density. By graphical and numerical regression analysis it was found that the stability increased with increasing depth of the groundwater table, with decreasing humus and clay content, and with increasing bulk density. We also found interactions between the effects of the different factors. For example, the effect of groundwater and bulk density was smaller in soils with a low organic matter content than in soils with much organic matter. That means that a good stability of the topsoil can be obtained with different combinations of drainage, bulk density and humus and clay content. However, we must select the combination which not only produces stability of the topsoil, but which also creates conditions favourable for the growth of grass throughout the year. From the last point of view somewhat deeper drainage (ca. 1m) in combination with some humus and clay in the top layer is preferred to other combinations."
