Anions X X Sulfate is an essential plant nutrient, chloride<br />

indicates buffering capacity at specific pH<br />

<strong>and</strong> also possible salt toxicity<br />

Cations X X Indicates availability of plants nutrients also<br />

(NA, K, Ca, Mg, Al, S, A, R) essential for<br />

saline soils. Al potential toxin at low pH<br />

Electrical conductivity (EC) X X X Indicates soluble salt status<br />

pH X X X Need to identify extreme ranges for<br />

treatment or selection of plant species. Also<br />

indicates likely availability & behaviour of<br />

plant nutrients with pH changes<br />

97<br />

Dispersion Index X X X Indicates Stability & erodibility<br />

Particle size analysis X X X Indicates stability & erodibility<br />

Classification (structure texture etc) X Allows existing data & experience on<br />

managing similar soils elsewhere to be<br />

applied<br />

8.4 Appendix 4 – Soil Tests<br />

Selected Tests for Soil, Overburden <strong>and</strong> Other Rooting Media*<br />

* Test <strong>and</strong> analysis will vary from site to site. In some cases, tests not listed above will be essential. Where topsoil is available <strong>and</strong> classifiable,<br />

existing information may enable adequate management. In general the more site specific the material being revegetated, the greater the need to<br />

determine the physical <strong>and</strong> chemical characteristics.<br />

Nitrogen X X X Indicates levels of nitrogenous fertiliser<br />

applications required <strong>and</strong>/or mix of plant<br />

species desirable<br />

Total Sulfur X X Important where acid forming potential exists<br />

98<br />

Lime Requirement X X X On low pH material only. Indicates amount of<br />

lime required to raise pH.<br />

Phosphorus X X X Important if non native species necessary for<br />

post mining l<strong>and</strong>use or where topsoil is poor<br />

or is not available.<br />

Minor Elements X X X Important as elements for plant growth (in<br />

soils) (Cu, Zn, Pb, Mn, Co, Mo, B, A) or as<br />

potential toxins in overburden or tailings etc.<br />
