Assessing the impact of biochar in the Herbert cane industry.
(2015)Biochar is the charred by-product of biomass pyrolysis, the heating of plant-derived material in the absence of oxygen in order to capture combustible gases. It is generally accepted that biochar is a highly stable form ... -
Herbert Water Quality Monitoring Project: final Report 2011/003
(Sugar Research Australia Limited, 2015)The Herbert River Catchment is situated in the Wet Tropics Region of Far North Queensland and covers approximately 10,000 square kilometers and unlike many other coastal streams in the wet tropics, the Herbert River has a ... -
Improvement of internal soil drainage and yield on heavy clay soils in the Herbert.
(2015)The Herbert consists of large areas of clay soils being approximately 60% of soils being sugarcane farmed within the region. These soils are usually nutritionally fertile; however yield potential is limited due to waterlogging. ... -
Nitrogen accumulation in biomass and its partitioning in sugar cane grown in the Burdekin : ASSCT peer-reviewed paper
(ASSCT, 2016)Nitrogen is a key component of metabolic processes in plants and due to its mobile nature in soils is often a limiting factor in achieving maximum yield in commercial sugarcane crops grown in Australia. Demand for N ... -
Spatially explicit estimation of Achievable Yield Potential – An improved basis for fertilizer management: final report 2015/070
(Sugar Research Australia Limited, 2017)Current practice in implementing the SIX EASY STEPS (6ES) is to use the ‘district yield potential’ (DYP) to guide development of nitrogen (N) fertilizer recommendations. However, because both land (soil, topography) and ... -
Delivering a novel DNA-based diagnostic for root health to the sugar industry: final report 2015/042
(Sugar Research Australia Limited, 2017)Plant root systems play many key roles including nutrients and water uptake, interface with soil microorganisms and resistance to lodging. Unfortunately, as for any other crop, large and systematic studies of sugarcane ... -
Role of controlled release fertilizer in Australian sugarcane systems: final report 2014/011
(Sugar Research Australia Limited, 2017)Controlled release fertilisers (CRFs) are promoted as a means to optimise the productivity achieved per unit of fertiliser nitrogen (N) input and lower environmental impacts from N leaching, runoff and emission losses. ... -
Burdekin Legume Fallow Discussion Sheet
(2017)Information sheet on legume fallow in the Burdekin. -
How much nitrogen will that crop need? Incorporating climate forecasting to improve nitrogen management in the Wet Tropics : Final project 2015/075
(Sugar Research Australia Limited, 2018)Determining the optimum amount of nitrogen that is required by the crop to maximise production, profitability and environmental outcomes is a challenging problem. The modelling approach taken in this project has balanced ... -
Strategies to manage soil-borne fungi and mitigate sugarcane yield decline : Final report 2013/101
(Sugar Research Australia Limited, 2018)Culture–dependent and culture-independent analyses of sugarcane rhizosphere fungal and oomycete communities were conducted across two cropping seasons at two sites. Agronomic treatments included replant continuous cane, ... -
Boosting NUE in sugarcane through temporal and spatial management options : Final report 2014/045
(Sugar Research Australia Limited, 2018)This collaborative project involved the University of Southern Queensland (USQ) and the Sugar Research Australia (SRA) Technology Unit. It aimed to evaluate methods of matching nitrogen (N) supply (from soils and fertilisers) ... -
Efficacy and environmental runoff impact of alternative pre-emergent herbicides to diuron applied on trash blanketed ratoons
(ASSCT, 2018)THE EFFICACY OF alternative pre-emergent herbicides to diuron applied just after harvest on green trash blanketed ratoons was investigated in three field trials in the wet tropics, Far North Queensland. The study also ... -
Regenerating a soil food web capable of improving soil health and reducing losses from soil borne pests and pathogens of sugarcane : final report 2014/004
(Sugar Research Australia Limited, 2018)When the Sugar Yield Decline Joint Venture concluded in 2006, its main legacy was a new sugarcane farming system based on legume breaks, minimum tillage, controlled traffic and trash retention. Many economic benefits were ... -
Decision support for choice of enhanced efficiency fertilisers - Herbert catchment pilot study : Final report 2017/015
(Sugar Research Australia Limited, 2019)Enhanced Efficiency Fertilisers (EEF) are of interest to the sugarcane industry because they have the potential to increase N use efficiency and reduce nitrogen (N) loss. However, agronomic and environmental benefits are ... -
Nitrogen availability from legume and past fertiliser history : ASSCT peer-reviewed paper
(ASSCT, 2019)It is likely that land-based activities within the Australian sugar industry have a negative effect on the quality of water in the Great Barrier Reef lagoon. Improvements to nitrogen use efficiency (NUE) are likely to ... -
Aspects of temporal N management in sugarcane in sub-tropical Queensland : ASSCT peer-reviewed paper
(ASSCT, 2019)The proximity of the Australian sugar industry to the Great Barrier Reef (GBR) has resulted in ongoing concerns about elevated concentrations of the dissolved inorganic nitrogen (DIN) in the near-reef environments due to ... -
Spatial distribution of potential soil constraints affecting nitrogen management in the Wet Tropics : ASSCT peer-reviewed paper
(ASSCT, 2019)Position in the landscape and climatic conditions experienced during the growing season, especially following the application of nitrogen (N) fertiliser, has important implications for crop growth, N uptake and N losses. ... -
Is magnesium deficiency a causal agent of sugarcane Yellow Canopy Syndrome? : ASSCT peer-reviewed paper
(ASSCT, 2019)Yellow Canopy Syndrome (YCS) is a disorder affecting sugarcane in the Australian industry, the cause of which is unknown. This paper reviews YCS research focusing on magnesium imbalance as a possible cause of the condition. ... -
Effect of long-term application of potassium on sugarcane and soil properties in the Herbert River district : ASSCT peer-reviewed paper
(ASSCT, 2019)Excess potassium (K) fertiliser use can have a significant effect on sugar quality and refining costs but offers no benefit to sugarcane crop yield. Potassium fertiliser guidelines are based on soil texture and two ...
