| Abstract/Contents: | "Selection of rootzone materials for sports turf areas is often based on laboratory measurements of physical characteristics after the material has been subjected to compaction. However, there have been reports of variation in test results between different laboratories and therefore work was carried out to investigate possible sources of variation. Differences in handling of material before receipt in a laboratory could have significant effects on measured properties. For example, breakdown of structural units within rootzone mixes to below 2 mm diameter reduced hydraulic conductivity by 10-20%. Reduced air-filled porosity and increased capillary porosity were also recorded. Drying of rootzones containing an organic matter source resulted in an increase in hydraulic conductivity of 32-35% and this was only partially reduced by re-wetting for 24 hours before the start of testing. The moisture content at which samples were initailly placed in cylinders had an effect on hydraulic conductivity and capillary porosity of a sand/soil mix. Effects were also recorded for total porosity, air-filled porosity and capillary porosity of a sand/peat mix. The procedure for wetting samples before equilibrium on a sand tension table affected hydraulic conductivity although this applied mainly to wetting solely by capillary rise. The amount of compaction applied to samples and the time taken before the determination of hydraulic conductivity had significant effects on soil physical properties, but were not considered to be a major source of variation unless gross errors were made in the testing procedure." |
