Review of nitrogen fertiliser research in the Australian sugar industry
(2004)The management of nitrogen (N) fertiliser is important to the Australian sugar industry, as it is an important nutrient for sugarcane production. However, over application results in reduced profitability and sugar quality, ... -
Improved environmental outcomes and profitability through innovative management of nitrogen SRDC research project CSE011 final report
(2008)Nitrogen (N) fertiliser additions are an important contributor to productivity and profitability in intensive farming systems, including sugarcane production. However, applying N increases losses of N to the environment, ... -
Evaluating the potential for improved sugar yields by assessing the climatic and soil constraints to production in southern cane-growing districts
(1999)This project conducted strategic research to better understand the processes of yield accumulation in low temperature NSW environments and to identify limits to yield. The fundamental knowledge gained in this project can ... -
Evaluating the leaf chlorophyll meter as a tool for nitrogen management in sugarcane
(1995)Nitrogen is an important constituent of chlorophyll, the compound that gives plants their green colour and the compound that absorbs radiation energy as the basis of plant growth. When nitrogen is in short supply, the ... -
A reference booklet for canegrowers on the nutrition and fertilizing of sugarcane for different soil types
(2003)A wide range of different soils are used for sugarcane production in the Herbert River district. An understanding of these differences both at district and farm levels will ensure that nutrient management reflects this ... -
Overcoming on-farm constraints to productivity and profitability in a wet tropical area
(2003)The CCS in the wet tropics has been declining steadily for over three decades, a period in which green cane harvesting-trash blanketing (GCTB) has become standard practice among growers throughout the wet tropics. In the ... -
A stocktake of the levels and sources of nitrate in groundwaters associated with sugarcane areas
(2000)Water containing high concentrations of nitrate is unfit for human consumption and, if discharging to freshwater or marine habitats, can contribute to algal blooms and eutrophication. Previous studies have found elevated ... -
Prediction and management of acidity production and export from acid sulphate soils used for sugar production final report SRDC Project DNR004
(2001)The experimental design of this project successfully enabled runoff and groundwater drainage flow components to be distinguished in a cane-farming context at Pimpama, southeast Queensland. The majority of acidity exported ... -
Nitrate retention at depth under sugarcane in Far North Queensland Wet Tropics
(2002)Nitrogen mass-balance studies for sugarcane grown on Ferrosols (Krasnozem) in the Far North Queensland (FNQ) wet tropics have shown 30 to 50 kg N/ha/yr of the applied fertiliser+N leached below the root-zone (<0.75 m) as ... -
Investigation of mangrove dieback Pioneer River Estuary, Mackay
(2002)This report discusses the results of an investigation to establish a potential cause of the mangrove dieback that has occurred within the Pioneer River estuary and Bassett Basin, Mackay, Central Queensland from 1998 to ... -
SRDC Research Project final report Development of a constructed wetland for improving water quality in sugarcane drainage, and ensuring its community acceptance and industry adoption
(2007)Canefield drainage water quality is an increasingly important issue for the industry and community because of the potential downstream environmental impacts of contained contaminants. The community is increasingly ... -
Final report SRDC Project CSR024 Improving the environment for sugarcane growth through the amelioration of soil acidity
(2002)Most soils used for growing sugarcane in wet tropical northern Queensland are highly acidic. Comparisons between new cane land and land that has been growing sugarcane for many years have demonstrated that our soils have ... -
Adopting systems approaches to water and nutrient management for future cane production in the Burdekin SRDC Research Project CSE020 final report
(2008)There is concern about environmental impacts of cropping in catchments of Australia’s Great Barrier Reef, especially losses of nitrogen (N) and herbicides from cropping systems. Sugarcane production in the Burdekin region ... -
Short and long term impacts of green cane trash blanketing on soil fertility
(2005)In the last three decades, there has been a widespread adoption of green cane harvesting-trash blanketing (GCTB) in the Australian sugarcane industry, generally motivated by the practical advantages (e.g. weed control, ... -
Sugar Research and Development Corporation final report Project CTA013 Spatial analysis of the impact of land use on nutrient loads within the Herbert River Catchment
(1998)This Project arose out of concerns for the apparent increase in nutrient and sediment contaminant loads in Queensland coastal waters since European settlement (e.g. DEAP Report, 1992). At the time of Project inception, the ... -
Sugar Research and Development Corporation final report Increasing sugar cane yields by improvements in soil structure
(1998)A project to increase sugar cane yields by improvements in soil structure was conducted at Broadwater, NSW. It was instigated in response to the poor physical structure of many cane soils and poor root development in many ... -
Final report SRDC Project CLW009 Improving yield and ccs in sugarcane through the application of silicon based amendments
(2003)Under high leaching environments common to the wet tropics, soils undergo significant weathering, which, when combined with accelerated chemical and physical degradation due to soil perturbation and crop removal, results ... -
Quantifying and managing sources of sediments and nutrients in low-lying canelands : Project no CLW007 - final report
(2003)Queensland’s north-east coast are used for sugar production. Various studies investigating sediment discharge from catchments where sugar is an important land use have demonstrated that sediment export from cane lands often ... -
Final report to the Sugar Research and Development Corporation CTA007 A modelling framework to integrate research on nitrogen management of sugarcane
(1996)This project used a measurement and modelling approach to explore the processes controlling nitrogen supply and losses in the crop and soil elements of sugarcane production systems. Measurements took place both in the field ... -
Environmentally sound phosphorus management for sugarcane soils : final report on SRDC Project no CSS3S
(1998)A field and laboratory-based survey of the behaviour of phosphorus (P) was carried out on the soils of the lower Herbert River catchment, and sediments derived from them. The aim was to explore the factors governing P ...
