  • Selective inhibition of ion absorption by uranyl

    Creator:
    Mason, Benjamin J.
    Abstract:
    The research presented in this thesis evaluated the effects of uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due to the biological importance of Na and K, these two ions were studied in the greatest detail. The results of this research showed that, at UO₂⁺⁺ concentrations...

  • The effect of selected potassium salts on the availability of soil manganese

    Creator:
    Westermann, D. T. (Dale Thomas), 1941-
    Abstract:
    Incubation experiments with an acid poorly drained soil have shown that the application of neutral soluble salts influenced the level of extractable Mn. The application of a salt which lowered the soil pH either increased the extractable Mn or retarded the oxidation and/or fixation of extractable Mn. This effect was...

  • Factors affecting establishment, survival, and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.)

    Creator:
    Cooper, Clee Scott
    Abstract:
    Field, greenhouse, growth chamber and laboratory experiments evaluated factors affecting establishment, survival and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.) Field studies investigated the effects of a barley companion crop, seedling year harvest management and nitrogen and phosphorus fertilization upon stands, survival and subsequent production...

  • Aluminum toxicity in wheat (Triticum aestivum Vill., host)

    Creator:
    Kerridge, Peter Campbell
    Abstract:
    Wheat varieties of differential tolerance to Al were used in a series of nutrient solution experiments to study the inhibitory effects of Al on growth and nutrient uptake. The pH and the Al and P concentrations were rigorously maintained to prevent the confounding effects of Al and P precipitation and...
