Objective:
The primary objectives of this project were to establish the relative tolerance of various perennial grasses and cover crops adapted to the climate of southeast Kansas to high concentrations of heavy metals, and to investigate the effectiveness of various soil amendments in reducing the plant availability of heavy metals in contaminated soils and mine spoils.Summary/Accomplishments (Outputs/Outcomes):
The soils in southeast Kansas, southwest Missouri, and northeast Oklahoma are contaminated with heavy metals because of past mining activities. Reclamation efforts aimed at establishing vegetation are needed. Organic amendments, pH adjustments, increased cation exchange capacity, soluble phosphorous additions, and dilution with uncontaminated soil are potential methods to improve vegetation. Metal-tolerant grass species can be seeded, also.
Greenhouse studies have been conducted on soil and mine spoil material from selected sites. Chemical, physical, and mineralogical characterization of the soil was carried out to determine plant nutrient status, pH, organic matter, lime requirements, particle size analysis, clay mineralogy, total metal content, and chelate extractable metals. Experiments with amended soils and controls were carried out with several plant species.
Results can be summarized in the general categories of characterization,
revegetation of chat, and reducing metal bioavailability to
row-crops.
Characterization: Numerous samples of soils and mine spoil
materials were collected in southeast Kansas and characterized according to
chemical properties and mineralogy. This characterization data was presented at
the 1991 Hazardous Substance Research Conference for USEPA Regions 7 and 8. The
primary limitation to plant growth was determined to be Zn toxicity. Seven plant
species were found growing in or near heavy-metal contamination sites. Their
common names are switchgrass, broomweed, sedges, common ragweed, bulrush,
indiangrass and hemp dogbane. It is possible that these species are tolerant to
high soil concentrations of metals.
Revegetation of chat: Chat is a rock waste material that is produced during the initial processing of the ores. Numerous chat piles occur throughout the Tri-State Mining region. As the fine particles selectively erode away from the piles, larger and larger areas are impacted by the heavy metals. Wind-blown dust is also the primary means of exposure for humans to Pb and Cd in these areas. A vegetative cover would prevent or slow the erosion process.
Blue grama grass, switchgrass, little bluestem, indiangrass, big blustem, tall fescue, KY31 tall fescue, Buffalograss, hairy vetch, sideouts grama, smooth bromegrass, red fescue and crown vetch were evaluated for their ability to grow in both unamended chat and chat amended with the equivalent of 2000 kg/ha of a sewage sludge/cement kiln dust combination. Big bluestem exhibited the best growth although none of the species had acceptable growth.
Reducing metal bioavailability to row-crops:
Cultivated areas within the floodplains of rivers that drain the mined areas
receive contaminated sediments during flooding events. Often such soils receive
Zn doses high enough to inhibit the growth of some row-crop species. There is
also concern regarding food-chain transfer of Cd and Pb. Two greenhouse studies
were conducted to evaluate the effectiveness of various soil amendments or
combinations of soil amendments on reducing heavy-metal bioavailability to
soybeans.
The first study compared 1120 kg CaCO3 equivalent/ha, 5000 kg/ha
cattle manure, 5000 kg/ha poultry manure, 2000 kg/ha of N-Viro soil (cement kiln
dust plus sewage sludge), 100 mg P/kg as K2HPO4, 100 mg P/kg as (NH4)2 HPO4, and
a control. The CaC03, cattle manure and N-Viro treatments were the most
effective in increasing soybean yields, reducing Zn, Cd and Pb concentrations in
soybean tissue and reducing bioavailability Zn concentrations in the soil, as
measured with a chemical fractionation procedure.
The second study looked at a factorial arrangement of CaCO3 rate (0, 1.12 and 2.24 Mg/ha) and cattle manure (0, 5 and 10 Mg/ha) to see if a combination of amendments would be more effective than a single amendment. Overall, the addition of CaCO3 was the most effective treatment as indicated by reductions in bioavailable Zn in the soil, increased soybean yields and decreases in tissue metal concentrations. The addition of cattle manure produced similar effects, although the relative differences were not as great as those for limestone. The addition of both materials produced significantly higher soybean yields as compared to either material alone for one harvest; however, in general, the combination of both amendments did not produce additional reductions in metal bioavailability as compared to limestone alone.
The studies on reducing metal bioavailability to row-crops were the most successful aspect of the project. Scientifically, a refereed publication was produced that has been well received by the scientific community. From a practical viewpoint, some realistic recommendations can be made to land owners who have soils with excessive Zn levels.
The results have been presented at professional meetings and workshops. They have also been communicated to other interested parties.
