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 ... -
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 ... -
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 ... -
Optimisation of nutrient management of the Queensland sugar industry : SRDC final report BSS176
(2002)This project, BSS176, set out to give the sugar industry an indication of how bringing nitrogen rates back to within BSES recommended levels would not only save production costs, but also improve ccs, thus improving ... -
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 ... -
Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
(1992)Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ... -
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 ... -
Progress report on BSES and WRC studies of water quality in Woongarra-Pemberton area - July 1981
(1981)This report summarizes results of a pot trial comparing bore and surface water; co-operative monitoring of water-table levels with the Water Resources Commission; field trials with various ameliorants; and a field survey ... -
Project 921 - rates of biodunder for sugarcane : final report
(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")
(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 ... -
Protecting our chemicals for the future through the accelerated adoption of best management practices : final report 2016/002
(Sugar Research Australia Limited, 2020)The project ran in the Wet Tropics for three years from September 2017. The project set out to improve water quality in Great Barrier Reef catchments through increasing the uptake of management practices to reduce losses ... -
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 ... -
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 ... -
Report on evaluation of nutrient enhancement of biodunder for cane growth
(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 ... -
Researching soil health and economics of two farming systems in the Herbert River district : SRDC Grower Group Innovation Project final report
(2009)The New Farming Initiative Group (NFIG) consists of six members and has approximately 600ha of sugarcane farming land in the Herbert region. Comparison of soil health of the two farming systems is the primary objective. ... -
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, ... -
A review of nitrogen use efficiency in sugarcane
(Sugar Research Australia Limited, 2014)The Great Barrier Reef (GBR) is the world’s largest coral reef ecosystem, providing both substantial economic benefit to Australia and significant international ecological value. The health of the GBR is under pressure ... -
Review of sodic soils research in the Queensland sugar industry
(1995)Increasing levels of sodium on the clay, in the absence of high levels of soluble salts, are not believed to be toxic to the cane plant. Any adverse effect on crop production is through deterioration of the soil structure ...
