    A Market Assessment for Potential Crops on Peatlands in Koochiching County
    (University of Minnesota Duluth, 1990-02) Van Hale, Thomas J; Johnson, Kurt W
    The objective of this paper is to provide a list of crops with sufficient markets that can be grown on the tax forfeited peatlands and stimulate economic growth in Koochiching County. The focus was on finding crops with significant markets such that large number of peatland acres could eventually be utilized for production. The market for broccoli, carrots, cauliflower, cabbage, and onions is large and growing. It should be able to absorb additional production from Koochiching County. In addition, the timing of the asparagus harvest may make it an ideal crop for the County. All of these crops can be grown on peatlands but additional work must be done in the production and marketing areas before an industry is developed. Production issues that must be addressed include varietal development and selection, site selection and accessibility, and production methods. A marketing infrastructure must also be developed. ~Even though these production and marketing concerns may eventually be addressed, the profitability of a large produce industry propably depends on the accessibility of land and the cost of clearing and the availability and cost of labor. Development of a produce industry in northern Minnesota will take money, time, and dedicated people. If Koochiching County decides to help develop the industry it should work with the organizations who appear to be leading the development: the Clearwater County Extension Office, Agricultural Utilization Research Institute at Crookston, Northern Minnesota Produce, and Kooch Grown.

    Mineland Reclamation using Office Waste Paper De-Inking Residue
    (University of Minnesota Duluth, 1994-03) McCarthy, Barbara J; Monson Geerts, Stephen D; Johnson, Kurt W; Malterer, Thomas J; Maly, Craig C
    Pulp facilities which recycle office waste paper generate a large amount of waste by-products in the process of producing high-grade pulp. The paper-like residue, called de-inking residue, was evaluated for use in the restoration of vegetation on coarse taconite tailings in NE Minnesota. The mineland reclamation rules specify that a 90 percent vegetative cover shall be established on tailings after three growing seasons, however this level of cover on coarse tailings has not been consistently achieved in Minnesota using standard restoration practices. Research plots were established in 1992 at Eveleth Mines arranged in a randomized block design with three replications using five levels of de-inking residue, five levels of fertilization and two plant mixes. A total of twenty-five treatment combinations were assigned to 2.5m- by- 4.0m plots and lysimeters were installed to monitor changes in sub-surface water quality. Coarse tailings were evaluated to determine the effects of de-inking residue on their chemical properties. Vegetative cover was measured in July and September in 1992 and 1993 and nutrient levels were determined in plant samples. Fertilization and de-inking residue amendments had significant effects on the vegetative cover of both introduced and native plant species. De-inking residue had a minimal impact on the chemical properties of coarse tailings at rates up to 80 dry ton/acre and on sub-surface water quality at a depth of four feet. Vegetative cover for introduced species increased from no cover, to 49 percent the first growing season, to 90 percent at the end of the second growing season on tailings fertilized at the highest level and amended with residue at 10 ton/acre. At the same fertilizer and de-inking residue rate, vegetative cover for native plants increased from no cover to 7 percent the first growing season, to 69 percent at the end of the second growing season. Alfalfa had lower levels of boron, magnesium, and manganese on residue amended plots in 1992 and 1993. Bluestem had higher levels of calcium and zinc, but lower levels of magnesium and manganese on residue amended. plots. Cadmium, chromium, copper, nickel, lead, and zinc in alfalfa and bluestem did not accumulate to toxic levels. Deinking residue appears to have benefited vegetative growth after two growing seasons using deinking residue applied at 10 dry ton/acre with fertilizer applied at 160 lb/acre of nitrogen and 359 lb/acre of phosphorus.
