    Varietal and fertilizer effects on straw phytotoxins (1986)
    Springer
    Biology and fertility of soils 2 (1986), S. 109-112

    ISSN: 1432-0789
    Keywords: Straw ; Phytotoxins ; Acetic Acid ; Wheat ; Barley ; Cultivar ; Nitrogen

    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Acetic acid production over 10 days from fresh barley straw was greater than that from fresh wheat straw, but there were only minor consistent differences between different cultivars. The effect depended on the soil type on which the straw had been produced and acid production was greatest with the largest amounts of N fertilizer which had been used. The fertilizer also affected the C:N ratio of the straw

    The role of water-soluble components in phytotoxicity from decomposing straw (1982)
    Springer
    Plant and soil 65 (1982), S. 11-17 
    Details
    ISSN: 1573-5036
    Keywords: Acetic acid ; Hot water-soluble components ; Phytotoxins ; Straw
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary When seedling development is slowed by the presence of straw in wet seed-beds both microbial products and compounds of plant origin contribute to phytotoxicity. Hot (100°C) water-soluble extracts from fresh straw contained phytotoxic substances but these accounted for less of the phytotoxicity than the microbial products, primarily acetic acid, from anaerobic fermentation of the insoluble straw polysaccharides (cellulose and hemicelluloses). The water-soluble components however also included mineral salts required in the decomposition of these polysaccharides.
