    Notes: Abstract  In long-term field experiments on sandy loam and loamy sand soils, the influence of conservation and conventional tillage on soil and rhizosphere microorganisms was studied. Conservation tillage stimulated rhizosphere bacteria on winter wheat, winter barley, winter rye and maize in different soil layers. Particularly the populations of Agrobacterium spp. and Pseudomonas spp. were increased. On the sandy loam, N2 fixation and nodulation of pea plants were significantly increased. No influence of different soil tillage was determined on the colonization of the rhizosphere by mycorrhiza and saprophytic fungi. Stubble residues infected with Gaeumanomyces graminis were infectious for a longer time on the soil surface than after incorporation into the soil.

    Description / Table of Contents: The products of the thermal decompositions of mixed carbonates, oxalates, and nitrates of copper and manganese have been investigated chemically and by x-ray techniques.Similarly, the products of interactions between Cu2O, CuO or Cu and MnO, Mn2O3 or MnO2 are studied.The double oxide CuMnO2 has been prepared in the pure state.
    Notes: Die thermischen Zersetzungsprodukte gemeinsam gefällter Carbonate und Oxalate sowie gemeinsam eingedampfter Nitrate des Kupfers und Mangans wurden chemisch und röntgenographisch untersucht. Gemische aus Kupfer(I)-bzw. Kupfer(II)-oxid sowie Kupfer einerseits und Mangan(II)-, Mangan(III)- und Mangan(IV)-oxid andererseits wurden im Sauerstoff- und Stickstoffstrom sowie im Hochvakuum umgesetzt und ihre Reaktionsprodukte chemisch und röntgenographisch untersucht. Das Doppeloxid CuMnO2 wurde erstmalig rein dargestellt.
