Soil development and plant growth in Collie coal mine wastes [Western Australia]
1991
McKissock, I. | Gilkes, B. (Western Australia Univ., Nedlands. School of Agriculture)
Levels of exchangeable cations were found to be very low on revegetated waste dumps, with extremely low levels of exchangeable K. Some materials were too acid for plant growth, so that liming was required. Bulk densities were high and increased with depth in the soil profile, sometimes restricting root growth. N values were low, with a mean value of 0.03 percent for surface materials, although values increased with age of the dump. Comparison with other coal mines and soils in Australia indicated that the present management of the Collie mine is appropriate, and that adverse properties of the wastes will improve with time.
