    Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
    (1992) Chapman, LS; Freney, R; Denmead, OT; Wood, AW; Saffigna, PG
    Objectives of the experiments were (1) Determine the extent of NH3 volatilisation when urea and ammonium sulfate are applied to the surface of a trash blanket in four cane-growing regions. Evaluate the effect of various placements of urea in a trash blanket under wet and dry moisture regimes by quantifying the amount of N recovered in the soil-plant system.

    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.
