“…Even where chemicals do not destroy vegetation, they can be assimilated by plants and passed into the food chain. Neuman and Munshower (1984), for example, showed that high molybdenum contents in coal mine soils led to copper deficiencies in cattle.…”

“…The mean value for the Cu:Mo ratio for plant tissues in the ecovar variety of blue wildrye was significantly higher than for the local variety of blue wildlrye and arctic lupine. All values were above the adverse-health threshold value suggested by Newman and Munshower (1984;Table 10).…”

“…discussing the potential for induced Cu deficiency (i.e., molybdenosis) in grazing animals. The mean Cu:Mo ratio in plant tissues collected from both soils (10.949 0.92 for 2-yr soil and 11.4491.27 for 10-yr soil) was considerably higher than the adverse-health threshold value of 2.0 suggested by Newman and Munshower (1984) and hence can be considered safe for animal consumption; plant tissues with a Cu:Mo ratio less than the threshold value have been shown to lead to adverse health effects.…”

“…Mean values of the Cu:Mo ratio differed considerably between plant tissues collected from treated (i.e., NAGS supplement and fertilizer) and non-treated stockpiled soils (values ranged between 9.73 and 15.29); however, all values were well above the adverse-health threshold value of 2.0 suggested by Newman and Munshower (1984); Table 9). This suggests that supplementing these stockpiled soils with NAGS, both alone or in combination with fertilizer, is unlikely to result in the production of vegetation cover that would pose a risk of molybdenosis to potential foraging ungulates.…”

“…Of particular concern when evaluating metal content in forage is the ratio of Cu to molybdenum (Mo). High levels of dietary Mo can restrict the utilization of Cu by depressing its solubility in the digestive tract through precipitation of insoluble copper thiomolybdate, often decreasing the absorption of Cu, thereby influencing the Cu:Mo ratio (Newman and Munshower 1984). Gardner et al (2012) investigated the use of biosolids as an amendment to mine soils and found increased Mo content in plant tissue to levels exceeding national standards for beef cattle [National Research Council (NRC) 1996].…”

Carson, A. W., Rutherford, P. M. and Burton, P. J. 2014. Desulphurized tailings serve as a useful soil supplement for mine reclamation. Can. J. Soil Sci. 94: 529–541. Soil is often in limited supply for use in mine reclamation activities; it may be necessary to build soils (Anthroposols) using locally available substrates. Eight test plots were established at Huckleberry Mine, Houston, BC, to investigate soil properties and evaluate the performance and metal uptake of plants established on stockpiled soils that were or were not supplemented with non-acid generating sand (NAGS) and fertilizer. Concentrations of total and extractable trace elements (including base metals) were lower in NAGS-supplemented soils than in non-supplemented soils. Supplementing soils with NAGS reduced cation exchange capacity and exchangeable base cations, yet plant performance was not significantly lower than that observed in non-supplemented soils. When combined with a fertilizer application, plant performance on NAGS-supplemented soils significantly increased. For heavy metals analyzed in plant tissues, only molybdenum (Mo) concentrations exceeded the National Research Council’s (NRC) recommended maxima for beef cattle. The copper (Cu):Mo ratio for all treatments was above a suggested adverse-health threshold value for ruminant feeds (with lesser values leading to adverse health effects). The use of NAGS (combined with fertilizer) as a supplement to stockpiled mine soil can increase the quantity of growth media for reclamation and is not expected to have any adverse effects on plant growth or the metal content in above-ground vegetation.

copper and molybdenum status of yearreclaimed mined-land and native range Spoil materhi repheed after 8trip mining for lignite co8l may differ from the origirui top soil with respect to concentrations of copper (Cu) and molybdenum (MO), consequently levels of these elements may be affected in plants grown on tbis soil. The objective of tbe study was to compare tbe Cu and MO status of yea&g steers grazing mined-land and native raoge forage to determine wbetber mined-land gazed steers were more prone to molybdenosis and/or Cu deficiency. Vegetation samples were collected from both mined-land and native range pasturea. Copper was marginai and MO was sligbtiy bigb, for beef cattle, in forage obtained loom both study sites. Blood serum and liver biopsy samples were taken from yearling steers at the initiation and termination of gr8zing on reclaimed mined-land and native range in 1978,1979,1982, and 1983. For the 4 years, there WNI no significant difference between forage sourcea with respect to Cu and MO levels in tbe liver or MO levels in tbe serum. However, serum Cu wn slightly (JY.10) lower in steers grazing on mined-land. Liver Cu levelr were marginal in steers grazing on either mined-land or native mnge. Initial liver MO levels were Igbtly above normal but did not increaae to levels expected if animals were consuming a diet excessively bigb in MO. No symptoms of Cu deficiency or molybdenosb were observed during tbe course of tbe study. However, ma&al serum, liver and forage Cu levels measured suggest that central North Dakota ranchers should be alert to the poesibiiity of a Cu deficiency, whether cattle are grazing reciaimed mined-land or nntive range.
