Identification of acid sulfate soils using a field peroxide pH test
(1999)This science project was conducted as part of Year 12 Chemistry to provide an assessment of the presence of acid sulfate soils on an Ingham property. The results will determine the extent of acid sulfate soil existence ... -
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, ... -
Improved nitrogen use efficiency through accounting for deep soil and mineralisable N supply and deployment of EEF to better match crop N demand : final report RRDP1717
(Sugar Research Australia Limited, 2020) -
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. ... -
Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
(1992)Objectives of the experiments were (1) Determine the extent of NH3 volatilisation when urea and ammonium sulfate are applied to the surface of a trash blanket in four cane-growing regions. Evaluate the effect of various ... -
Improving the management of acid and sodic soils with green trash retention using calcium-based ameliorants/products : SRDC final project report BSS199
(2003)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 ... -
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 ... -
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. ... -
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 ... -
