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 ... -
Acid sulfate soils in canegrowing regions of northern New South Wales
(1995)Acid sulfate subsoils contain iron pyrites (FeS2). Pyrites is stable under anaerobic (saturated) conditions, but when oxidised forms sufuric acid and releases mobile Fe2+ ion. Soil pH can be reduced to as low as 2 and ... -
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 ... -
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 ... -
Final Report SRDC Project BS98S Factors Affecting the Residual Value of Lime
(1996)Project was initiated to determine the relative significance of soil acidity and soil calcium status for predicting response of sugarcane to lime in southern Queensland, where recommendations developed for tropical soils ... -
Final Report SRDC Project BS146S Farming Sodic Soils - A Situation Statement and Future Direction
(1997)Aims of project were to document research on, and farming systems for, cropping sodic soils to sugarcane, and through an expert review of research and current practices for farming sodic soils identify directions for future ... -
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 ... -
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 ... -
Technical Report - Evaluation of a Roving Capacitance Probe for Measuring Soil Moisture
(1998)In the Proserpine area of central Queensland, Australia, trials were conducted to evaluate the performance of a proving capacitance probe for determining soil moisture. Soil moisture was monitored using both a neutron ... -
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 ... -
Farming systems for green cane trash blankets in cool wet conditions : SRDC final report BS63S
(1998)The three year project to evaluate different farming systems for green cane trash blanketing in cool wet conditions was directed at; evaluating the effect of different trash management practices on crop growth; evaluating ... -
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 ... -
SRDC Final Report - Project BS142S: Economic cost of soil compaction
(1999)Objectives of this project were: Adapt a Scandinavian model to determine the effect of soil compaction on crop yield for the Australian sugar industry; Relate crop response to degree of compactness by examining current and ... -
Final report on SRDC project CLW002 (previously CSS02 & CSS2S): The role of root growth and activity in determining sugarcane productivity
(1999)When the current project was initiated, poor root growth and activity were widely believed to be a major constraint to sugarcane productivity. However, there was no technology available to assess whether or not root growth ... -
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 ... -
Sugar Research & Development Corporation final report Pesticide transport in sugar production systems
(2000)The fate and persistence of a number of the key pesticides used in Australian sugar production have now been quantified for a range of soil types and conditions, In general there is no evidence of season-to-season build ... -
Final report - SRDC project BSS142 : Economic cost of soil compaction
(2000)This project was developed as a result of a study tour undertaken by Dr Braunack (Braunack, 1994) where the concept of the degree of compactness was thought to be applicable to the Australian sugar industry.The overall aim ... -
Final report - SRDC project BS145S : Improving sett/soil contact to enhance sugarcane establishment
(2000)This project had three objectives that were achieved in the following order: quantify the crop establishment practices of canegrowers within the major regions of Queensland and New South Wales; quantify the improvement in ... -
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 ...
