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 ...
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 ...
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 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 ...
Development of criteria for draining shallow watertables in the Isis irrigation areaFinal report SRDC Project BS12S
(1993)
This project was proposed to the Sugar Research Council because qualitative data suggested a significant problem with waterlogging and salinity in hydromorphic sedimentary soils in the Bundaberg to Maryborough region. ...
The effect of soil physical properties on growth and yield of sugarcane
(1991)
The literature reporting the effect of soil physical properties on sugarcane growth and yield has been reviewed and areas for further investigation are suggested. There is conflicting evidence in relation to the number ...
The effect of zinc deficiency as a factor limiting sugarcane growth (SRC Project BS14S - Final Report)
(1990)
Results from this project confirm that substantial yield responses to zinc application can be expected in deficient soils in North Queensland. Deficiency is commonly associated with lime application. Three soil and two ...
Extent of zinc deficiency in cane growing soils of North Queensland.SRDC Project BS67S - Final report.
(1993)
Collation and interpretation of soil analysis data has shown a strong relationship between soil type and extractable zinc. Extractable zinc in soils followed the order: metamorphic, beach ridge and granite soils < organic ...
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 ...
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 ...
