Soil compaction and soil contamination are two common causes of land degradation on sites reclaimed after surface coalmining. Since land degradation is more easily prevented than cured, soil quality standards designed to focus land reclamation agencies on potential problems, supported by a system of sustained post-project land quality inspection and enforcement, may be the best route to underwriting the long term productivity of reclaimed lands. This paper opens discussion on the determinationof appropriate measuresof soil quality. It has~foci: soil physical structure, soil acidity, and soil contaminationby heavy metals. It is suggested that successfully reclaimed land should have soil bulk densities that do not exceed 1.6 g/cm. 3 within 50 em of the surface and 1.8 g/cm 3 within 100 em.Further. successfully reclaimed lands should have a soil pH which does not exceed the bounds pH (3.0) 3.5 -8.5 (9.0) within ISO em of the soil surface. Trigger concentrations for the recognition of heavy metalcontaminationare suggested,Particularattention should be given to the metals most frequently associated with human health problems: cadmium. lead, and to a lesser extent arsenic, mercury, and radionuclides such as uranium. Since many problems associated with soil decline build up over time, it is proposed that these conditions should obtain through inspection tests conducted at reclamation. then 10 and 20 years subsequently. It is emphasised that all of the guideline levels proposed are arbitrary. The inter-relationships between bulk density, soil acidity, heavy metal contamination, and other aspects of the soil system are complicated and, in most cases. not entirely determined by the research community.

“…The layer of soil cover, typically mixed with foliage and litter, together with clay and mineral particles maintain the soil's water storage capacity-vital for plant growth [9]. Removal of topsoil as part of typical mining practices severely depletes soil nutrients such as nitrogen, carbon, phosphorus and sulfur [10]. Soil organic matter (SOM) provides energy for micro-organisms that unlock nutrient sources for all living organisms in the rhizosphere [11].…”

Determination of Soil Properties and Fungal Interrelations Influenced by Forest Restoration on a Contaminated Zinc Mining Area

2019

Forest restoration in a contaminated zinc mining area must take into account the environmental soil properties. This study aimed to analyze the soil properties from the three different stages of restored forests, at 3, 7 and 17, focusing on the impact on soil microorganisms and availability of fungal species. Three study sites were selected, all located in a zinc mining area in Mae Sot District, Tak Province, Thailand. The results showed that observed soil properties especially soil texture, moisture and nutrients differed between stand initiation and regrowth forests and affected the distribution of fungal species. Soils in older forest stands up to 17 years old showed higher sand content and reduced soil moisture, SOM, and certain nutrients. Forest restoration was found to favour development of a range of soil properties, some of which were suitable for fruiting in nine fungal species from the following families: Agaricaceae, Psathyrellaceae, Cantharellaceae, Phallacae, Coprinaceae, Sclerodermataceae, Lycoperdaceae, Marasmiaceae, and Clavariaceae.

“…A full description of soil profiles at each site has been given elsewhere (Davies et al, 1992). Both sites consisted of 25-30cm of topsoil overlying subsoil, 70-80cm deep at the control site and 90cm deep at the restored site.…”

“…Soil moisture content at both sites was measured at four depths (10cm, 20cm, 40cm and 70cm) on a 14-day cycle using duplicated access tubes and a neutron probe. Moisture content was converted to soil matric potential using an equation derived fronj moisture release curves (Davies et al, 1992). The field capacity of these soils was taken as -5kPa for the topsoil and -lOkPa for the subsoil, and the permanent wilting point as -1500kPa (Milthorpe and Moorby.…”

The growth of grass and clover components in mixed swards on a site restored after opencast coal mining and an undisturbed control site were compared. Soil nitrogen supply was reduced at the restored site. This inhibited grass growth but was beneficial for the clover component.Growth at the restored site was also inhibited by a compacted subsoil, which reduced available soil water content and impeded access to available soil water. This inhibited crop production from the middle ofthe second silage crop onwards. In 1989 this was associated with the soil at the restored site reaching permanent wilting point at 40cm. In 1990 this effect was associated with the restored site soil reaching permanent wilting point at 70cm. These drought effects reduced clover growing point population and stolon mass. Grass tiller populations were unaffected.
