    Productivity performance of climatological sub-regions within the Tully Mill area : ASSCT peer-reviewed paper
    (ASSCT, 2019) Stringer, JK; Skocaj, DM; Rigby, A; Olayemi, M; Everingha, YL; Sexton, J
    Inter-annual climate variability has a significant impact on productivity in the Wet Tropics region. Climate also varies spatially, yet the impact on productivity is less well known. Two distinct climatological sub-regions (northern and southern) have been identified within the Tully mill area based on total annual rainfall and annual average daily radiation. The wetter northern sub-region is characterised by lower radiation, lower temperatures and higher rainfall than in the drier southern sub-region. Mean cane and sugar yields were analysed for the two climate sub-regions using block productivity data obtained from Tully Sugar Limited for 2000 to 2017. After excluding 2011 (Tropical Cyclone Yasi), only farms with 15 or more years of data were included. The impact of spring-summer (SONDJF) rainfall and El Niño Southern Oscillation (ENSO) phases on cane and sugar yields in the two climate sub-regions was also analysed. On average, the northern, wetter climate sub-region yielded less cane and sugar yield than the southern, drier sub-region. There were significant differences between SONDJF rainfall terciles (dry, normal and wet) and ENSO phases (El Niño, Neutral and La Niña) for cane and sugar yields in the two climate sub-regions. Cane and sugar yields were significantly lower in years experiencing high SONDJF rainfall or in the La Niña phase. This analysis validates the results of the analyses used to derive the two climatological sub-regions in Tully. Improved knowledge of how climatic conditions influence sub-regional productivity performance will assist industry extension programs and on-farm management decisions.

    Adoption of practices to mitigate harvest losses : ASSCT peer reviewed paper
    (ASSCT, 2019) Patane, P; Landers, G; Thompson, M; Nothard, B; Norris, CA; Olayemi, M
    Harvesting Best Practice (HBP) recommends that harvesters maintain pour rates of 80-90 t/h, depending on make and model, and recommends extractor-fan speed guidelines that ensure minimal cane loss with low extraneous matter (EM). Exceeding the recommended pour rate overloads the cleaning capacity of modern harvesters and increases EM in the cane supply. To attempt to counterbalance the EM issue, it is usual to increase fan speeds above those recommended, resulting in greater cane loss. Use of HBP recommendations across the industry is low and full HBP adoption would substantially increase industry revenue. To address this, 43 replicated harvesting trials and workshops were undertaken in the 2017 harvest season across 12 sugarcane regions between Maryborough and Mossman. The performance of settings recommended by HBP were compared with each harvesting operation’s standard practice by assessing yield, CCS, bin mass, EM, fibre, sugar loss and revenue. To highlight the strong relationship between cane loss and excessive pour rates and fan speeds, treatments with higher pour rates and fan speeds and lower pour rates and fan speeds were also trialled. Results were presented to each harvesting group to inform their decision-making and promote HBP adoption. Cane loss, production and revenue data from 28 replicated and randomised trials were analysed to identify differences between industry standard harvesting practices and those recommended by HBP. We found that harvesters are typically operated at ground and fan speeds that are on average 1 km/h and 95 rpm above those recommended. The higher ground speed delivered an additional 22 t/h of cane into the machine on average but overloaded the cleaning capacity of the harvester. While the higher fan speed helped to remove the additional EM entering the machine, it also removed additional cane through the extractor with most being disintegrated, making it invisible to stakeholders. Testing indicated that mean sugar loss out of the extractor was increased by 0.15 t/ha compared with HBP settings, while there were no significant differences in EM or bin mass. Due to the additional cane being lost, less cane was delivered to the mill per hectare. Mill results across all trials identified that mean cane and sugar yields for the recommended practice were 5 t cane/ha (5.4%) and 0.8 t sugar/ha (5.7%) higher than standard practice. Neither CCS nor fibre levels were significantly different. The increased cane and sugar yields generated by the recommended settings boosted mean total grower revenue by $220/ha, equating to $173/ha after subtracting the additional harvesting costs (including fuel) and levies. Extrapolating these findings across the Australian green-cane-harvested area, full adoption of the recommended practices could deliver an additional 1.3 Mt of cane and 202,000 t of sugar valued at over $86 million for industry ($57 million in additional revenue for growers alone).

    Development of an Intelligent Tool to allow real-time evaluation of harvesting practices as part of a framework for improved harvester payment systems : final report 2016/951
    (Sugar Research Australia Limited, 2019) Norris, CP
    The project has resulted in the development of a cane loss indicator which can be a valuable tool to assist the harvester operator to optimise harvester performance as crop conditions change throughout the day. The system differs from previous attempts at cane loss monitors in that it does not attempt to identify individual billet loss, but rather looks at the energy dissipated in the processes of extracting cane and leaf and the effective dissociation of the billets as they are processed by the harvester extractor fans. The relationship between power consumption and actual cane loss utilises both keyboard inputs and parameters measured on the harvester. Data collection for the development of the algorithms and their calibration was undertaken in conjunction with field trials, where conventional cane loss measurement protocols were used to give the base data. Initially manual data collection strategies were utilised, followed by high accuracy data logging. The relationships observed between derived cane loss and measured cane loss in these trials allowed fine tuning of the algorithms, including the “weighting” of different measured inputs. Analysis of all datasets of electronically logged data indicates the repeatability of the cane loss values derived by SCHLOT under typical harvesting conditions to be high and, where variance was observed between the SCHLOT estimate and the field testing protocols, the SCHLOT number could be argued to give the more accurate determination of actual cane loss. In operation, the SCHLOT cane loss monitor gives highly useful feedback to the operator, and this drove significant changes in operating strategies by the harvester operator. The ability to remotely log cane loss in conjunction with other parameters such as harvester speed in near real time offers very significant benefits for the Industry with respect to the implementation of Best Practice Harvesting.

    Measuring the profitability and environmental implications when growers transition to best management practices : final report 2014/015
    (Sugar Research Australia Limited, 2018) Connolly, C; Renouf, M; Poggio, M; Thompson, M
    The development of sugarcane Best Management Practices (BMPs) aims to improve the productivity, profitability and sustainability of sugarcane farms. However, there has been limited research that has examined both the economic and environmental implications of BMP adoption on commercial farms in Australia. To alleviate this problem, this project has undertaken a literature review and six case studies on commercial farms in the Wet Tropics analysing the farm profitability and life cycle environmental implications of BMP adoption. After completion, case studies were distributed and extension materials were presented to industry.
