5.3 Neutralisation of Disturbed ASS

The calculated liming rate for the natural silty clay soils based on the results of the Chromium Suite results is
given in Table 3 (and on the laboratory report sheets included in Appendix B) and is 2 kg of ag-lime/tonne of dry
natural silty clay soils, based on a factor of safety of 1.5 and the use of good quality fine ag-lime with a
neutralising value of 100 %.

It is suggested that consideration be given to the adoption of a neutralising value of 80 % in calculation of the
required liming rate to allow for potential inconsistencies in the quality of the ag-lime. The calculated liming rate
using a neutralising value of 80 % for the ag-lime would be approximately 3 kg dry natural silty clay soils.
