Evaluation of biostil dunder and mixtures with nitrogen fertilisers for sugarcane nutrition
Chapman, LS; Usher, JF (1990)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 ... -
Evaluation of nutrient enriched biodunder for sugarcane : a review
Chapman, LS (1995)The review looks at the advantages and disadvantages of fertilising with biodunder\urea compared with applying biodunder and urea separately. The review concludes with 6 recommendations for the use of biodunder\urea\sulfuric ... -
Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
Chapman, LS; Freney, R; Denmead, OT; Wood, AW; Saffigna, PG (1992)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 ... -
Project 921 - rates of biodunder for sugarcane : final report
Chapman, LS (1995)The BSES recommendation for a maximum application rate is considered adequate to maximise returns and production for ratoon crops on the majority of Mackay soils. As the experiments were conducted only on ratoon crops, ... -
Project No 2025: Final report bench testing of new nitrogen products for potential ammonia volatilisation: when boradcast onto soil or sugarcane trash (N-gold "A", N-gold "B")
Chapman, LS; Haysom, MBC; Makepeace, P (1996)N-Gold "A" and N-Gold "B" are granulated products containing urea and calcium oxide with 42.4 and 43.2 % N and 1.5 and 1.3 % Ca respectively. When broadcast onto soil or a green cane trash blanket, ammonia volatilisation ... -
Report on evaluation of nutrient enhancement of biodunder for cane growth
Chapman, LS (1992)Three yield trials were conducted to evaluate strategies for the use of biodunder as a fertiliser for sugarcane. Cane growth in the trials was adversely affected by the weather, which was dry in summer, followed by ...
