Abstract
Plant samples collected from mined and test sites in surface coal mined areas of North Dakota were analyzed for nutrient concentrations. The vegetation from the mined areas generally showed lower concentrations of na, p, and cu and failed to meet the nutritional requirements for beef cattle as defined by the National Research Council. Some plants showed generally higher concentrations than others, and lower concentrations of p were reported in most of the plants on some unmined sites. Amending the spoil with slack at one test site decreased the concentrations of zn, cu, and p in wheatgrasses grown on spoil from 0- to 2-, 5- to 10- , and 20- to 25-foot depths, respectively. Leonardite amendment at one test site decreased p concentration in grasses compared with control, whereas fertilizer increased the same. The concentrations of ca, mg, na, fe, cu, and n in grasses were significantly higher on topsoil than at slack-amended spoil at one test site. The data presented in this report act only as an indication of between- treatment and between-species differences in tissue composition of plants harvested in midsummer season. Since none of the nutrients analyzed were found toxic, the cattle can safely feed on the mined land vegetation.
