    Analysis of field and factory options for efficient gathering and utilisation of trash from green cane harvesting : SRDC Final report BS157S
    (2000) Ridge, DR; Hobson, PA
    The objectives of this project were: to determine field costs for harvest\transport of cane with varying levels of cleaning by the harvester; to determine similar costs for field to factory transport; to establish the total industry cost of the various options; to determine the feasibility of cleaning at the mill; and to determine the economic feasibility of importing and burning additional extraneous matter for co-generation of power.

    Improving the management of acid and sodic soils with green trash retention using calcium-based ameliorants/products : SRDC final project report BSS199
    (2003) Schroeder, BL; Noble, AD; Robertson, FA; Nelson, PN; Wood, AW
    Although the advantages of leaving cane residues on the harvested land have been well documented, and nutrient cycling in relation to green-cane trash blanketing has been well examined within a Cooperative Research Centre for Sustainable Sugar Production (CRC Sugar) program activity, little work has been done to investigate the effects of trash management on soil chemical properties and the ameliorative advantages of applying Ca-containing amendments to crop residues. As lime, lime/gypsum applications are generally used to ameliorate acid soil conditions, a Ca-source followed by leaching is the principal strategy for managing sodic soils, and mill by-products (mill mud and mill ash) are often applied to plant cane, it was considered pertinent to investigate the effects of these and other amendments on the decomposition of trash on sugar industry soils.This project aimed at quantifying the effects of trash retention on soils acidity, examining the efficacy of Ca-containing amendments and trash for ameliorating sodic soils, assessing the effect of Ca-based amendments on trash decomposition and nutrient availability, and quantifying trash decomposition and C and N relationships. To do this, the project comprised four distinct but interlinked facets and included a series of laboratory investigations, glasshouse experiments and a field trial.

    Sustaining un-burnt production systems in cool wet environments : SRDC Final report BSS168
    (2002) Kingston, G; Davis, RJ; Parsons, D; Chapman, FL; Aitken, RL; Nielsen, PJ
    This project was initiated because the Green Cane Trash Blanket (GCTB) system had been rapidly adopted within tropical districts of the Queensland sugar industry between 1984 and 1990, yet there was minimal adoption in the cool and humid districts in northern NSW. Broad adoption in the tropics was interpreted by the community as a signal that the GCTB system was suitable for the whole of the Australian sugar industry; this was particularly the case in northern NSW where there is a high reliance on the tourist industry, with an little tolerance of the ash and smoke fall-out associated with the burnt-cane system. Additionally this region has a significant non-cane affiliated population, which is also non-sympathetic to the issues associated with the pre-harvest burning of sugarcane.

    Quantifying the socio-economic impacts of harvesting residue retention systems : SRDC Final report BSS173
    (2002) Small, FG
    BSS173: 'Quantifying the socio-economic impacts of harvesting residue retention systems' is a project jointly funded by the Sugar Research and Development Corporation and Land and Water Australia (formally Land and Water Resources Research and Development Corporation) from 1996 to 2002.The project was initially established after concerns that regulations on burning cane overseas would be introduced in Australia, and the socio-economic implications would not be known. There are a number of issues associated with burning of cane both before and after harvest. These include health concerns, pollution, nuisance and cleaning issues.The effect of the imposition of burning restrictions on growers was also a major concern, particularly with respect to furrow irrigation. Field trials were carried out in the Proserpine district to determine the effect of trash on furrow irrigation and to develop management methods to overcome any difficulties. These trials were used in conjunction with APSIM, an agricultural production simulator, and SIRMOD, a surface irrigation model, to determine optimal furrow irrigation under a number of situations.

    Development of a trash rake : SRDC Final report BS144S
    (1999) Davis, RJ; Chapman, FL
    Objectives of project were: to evaluate the performance of selected commercial rakes under various field conditions; to assess the ratooning vigour of varieties after raking trash from the stool area; to develop an improved trash rake to remove trash from the stool; to disseminate information derived from this project to the industry via publications and extension programs and enable demonstrations of trash raking.
