31  Soil acidity management—management action
 (1) For this determination, soil acidity management, as part of sustainable intensification, means a management action that:
 (a) is carried out on land on which, immediately before the start of the action, the average soil pH as measured in calcium chloride (CaCl2) was less than one or both of the following:
 (i) 5.5 in the surface soil (0–10 centimetre depth);
 (ii) 4.8 in the subsoil (below 10 centimetre depth); and
 (b) involves applying lime to decrease the soil acidity.
 (2) Before soil acidity management is undertaken as a management action in a carbon estimation area, the project proponent must obtain a soil acidity management strategy that complies with section 32.
 (3) Soil acidity management is taken to commence when lime is first applied to the carbon estimation area under the soil acidity management strategy referred to in subsection (2) and in accordance with this determination.
 (4) Subject to subsection (5), lime must be reapplied in accordance with a soil acidity management strategy.
 (5) Subject to subsection (6), lime must be reapplied at whichever is the more frequent of the following:
 (a) the interval specified in the soil acidity management strategy;
 (b) every 5 years.
 (6) A project proponent does not need to reapply lime to the carbon estimation area if appropriate testing indicates that the average soil acidity for that area is more than pH 5.5 for both surface soils and subsoils.
 (7) While soil acidity management is a management action, appropriate testing of the carbon estimation area must be undertaken at least every 5 years after soil acidity management commences in the area.
