Initial Vegetative Cover on Coarse Taconite Tailing Using Organic Amendments on Minnesota's Mesabi Iron Range

Abstract: Abstract. Mineland reclamation rules in Minnesota require that tailing dams be constructed and vegetated to control wind and water erosion for dam stability, safety, and dust control. Coarse !aconite tailing used in dam construction tend to resist vegetation stabilization due to several adverse edaphic factors, including: 1) alkaline reaction; 2) lack of organic matter; 3) lack of fine texture; 4) low water-holding capacity; 5) low cationexchange capacity; 6) lack of plant-available nutrients, particularly nit… Show more

“…The analysis of coarse tailings document the inherent poor chemical characteristics that impact the establishment and growth of vegetation at Eveleth Mines. The pH of coarse tailings was 8.7, similar to the pH on adjacent USBM plots (Norland, Veith, and Dewar 1991). Coarse tailings did not contain high soluble salt concentrations, as shown by a low mean conductivity, that would impair plant growth.…”

“…The low CEC and organic matter content of coarse tailings severely limits the ability of tailings to retain both available water and nutrients for plant growth. The levels of nitrogen and phosphorus in coarse tailings were low, as found on adjacent USBM plots (Norland, Veith, and Dewar 1991). The total concentration of potassium in tailings suggests that this macronutrient is at a high level.…”

“…In a companion study (Melchert et al 1994), MSW compost was applied to a tailing site to examine impacts on water quality and runoff. In recent years other studies have been initiated by the MDNR and the U.S. Bureau of Mines, studying the usefulness of MSW compost as a soil amendment for revegetating coarse !aconite tailing (Norland et al 1991(Norland et al , 1992(Norland et al , 1993. The objective of this paper is to assess tree growth and trace metal concentrations in leaf tissue for trees planted in coarse tailing plots treated with four rates of MSW compost.…”
