    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.

    Evaluation of biostil dunder and mixtures with nitrogen fertilisers for sugarcane nutrition
    (1990) Chapman, LS; Usher, JF
    The aims of this project were: (a) to measure the cane and sugar yield responses from the application of biostil dunder on its own and in mixtures with nitrogen fertilisers in field trials; and (b) to assess the suitability of these treatments for sugarcane nutrition. These treatments relate to a possible management strategy on cane farms, ie to broadcast sufficient phosphorus fertiliser on fallow land for the crop cycle, and then use a mixture of dunder and nitrogen fertilisers to provide the total N and K requirements for each crop in a single field application.
