    Farming systems for green cane trash blankets in cool wet conditions : SRDC final report BS63S
    (1998) Ridge, DR
    The three year project to evaluate different farming systems for green cane trash blanketing in cool wet conditions was directed at; evaluating the effect of different trash management practices on crop growth; evaluating improved drainage as a means of reducing any negative effect of trash blanketing. Trials were established at Childers and Rocky Point on relatively poorly drained soil types to compare full trash blanketing with trash raking off the cane row and bare cultivation; and, to determine any benefits from hilling-up or mole drainage in trash blanketed blocks. The trial sites were land planed at Rocky Point to improve surface drainage but this was not possible at Childers. The Rocky Point sites were dryland and the Childers sites received supplementary irrigation. The objectives of the report was to; determine the factors which affect ratooning under green cane trash blankets in cool wet conditions in south Queensland; to identify and demonstrate the cultural practices which minimise these factors; to extend the adoption of green cane harvesting in areas where this practice is considered appropriate.

    Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
    (1992) Hurney, AP; Ridge, DR
    Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ratooning varieties to the cold conditions or poor aeration, or whether there are toxic effects attributable to trash residues, ie allelopathy. The project was a preliminary investigation to assess potential allelopathic effects from trash residues on the growth of sugarcane. It was concentrated mainly on north Queensland soils and varieties due to the high percentage of trash retention in that area. A smaller test program was carried out at Bundaberg to take into account a wider suite of varieties and soils.
