| Abstract/Contents: | "The root-zone of an English Premier League soccer pitch deteriorated rapidly when play took place in wet weather despite having an organic matter content and particle size distribution normally found to be satisfactory. The root-zone was examined with the aim of accounting for its failure. The root-zone was uniform in composition. Somewhat less than half of the total organic matter content of around 2.5% could be dispersed. When the normal USGA method of root-zone pre-treatment was carried out prior to measuring physical properties, hydraulic conductivity was reduced to around one tenth of that measured after slightly moist root-zone samples had been compacted directly, and, was only one thirtieth of the expected hydraulic conductivity. Total porosity, and the balance of air and water-filled porosities at 40cm tension were unaffected by pre-treatment. The experimental data, supported by visual examination of thin sections of root-zone, indicated that organic-rich material became dispersed into the saturated pore-space by mechanical disturbance and trapped in constrictions between particles and in the necks of pores. The jelly-like colloidal components of organic matter were the fractions involved, which were associated with clay particles. It is asserted that the nature of the soil source used in sand/soil mixes affects the susceptibility of organic constituents to disperse and segregate. The mechanism identified is probably a common cause of deterioration of sand dominant root-zones." |
