    Improved environmental outcomes and profitability through innovative management of nitrogen SRDC research project CSE011 final report
    (2008) Thorburn, P; Webster, T; Biggs, J; Biggs. I; Park, S
    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, and so all intensive agricultural industries face the challenge of maintaining productivity while minimising environmental impacts of N fertiliser use. This challenge has become particularly important for sugarcane production in Australia because community concern grows over the impact of N on the health of the Great Barrier Reef and sugarcane production has the largest use of N fertiliser in the region. It has been suggested that replacing the N lost from a crop through harvested cane and environmental losses will better align N fertiliser applications to the actual needs of sugarcane crops and the other potential sources of N available to the crop, and so improve the financial and environmental sustainability of the Australian sugarcane industry. In this project we tested and further developed an innovative N fertiliser management system, the N Replacement (NR) system.

    Nutrient management from variable rate technology in a control traffic system by the Oakenden Grower Group : SRDC Grower Group Innovation Project final report
    (2008) Muscat, J
    The aim of the project is to determine the benefits of nutrient management system in a controlled traffic farming enterprise in an environmentally sustainable manner. The project will determine the cost benefits by comparing the conventional nutrient application to variable rate application. It will determine the difference between narrow chute planting and wide chute planting. The project will compare different legumes and the impact on the following cane crop. Oakenden Grower Group has documented a fact sheet to enable growers some insight when choosing a GPS system in a question and answer style information sheet. The Oakenden Grower group was keen to understand the economic impact of these trails which are highlighted in the trial results.

    Maximising soy's in Central Queensland : SRDC Grower Group Innovation Project final report
    (2011) Mattsson, S
    The Mackay region is currently expanding into soybeans as a legume for green manure and for grain production. The lack of region specific information has meant that growers are relying on information that has been developed in other regions. Some of this agronomic or varietal advice has resulted in crop failure when applied in the central region. Soybean crops in the central region are often lower yielding and have a higher frequency of failure than in other cane growing regions due to the lack of good local understanding of the crop. Our region’s climatic conditions such as: day length, temperature, rain fall and the number of rainy or clear days will impact on soybean production. These needs must be addressed to further encourage the adoption of legume break crops in the central region. Soy bean yields in the central region have not reached their potential when compared to the other regions and we believe that some of the issues relate to poor variety selection and the lack of good local information. This project experimented with current and new varieties and documents the results of these experiments. This information will give cane growers in the central region a process for better decision making.

    Sugar yield decline joint venture, phase 1 : SRDC technical report
    (2000) Garside, AL
    This report is a technical summary of the research carried out in Phase 1 of the Sugar Yield Decline Joint Venture (SYDJV) which ran from July 1993 to June 1999. Initially, the resources/funds for Phase 1 were provided by SRDC, BSES and CSIRO Division of Soils (now Land and Water) as core contributions to the Joint Venture. Much of the research carried out in Phase 1 was funded by these core contributions.In 1995 the Queensland Government Departments of Primary Industries and Natural Resources joined the SYDJV with funding provided by the Sugar Industry Reference Panel (SIRP). Research carried out with this funding included the southern rotation experiment and southern component of the strategic tillage work at Bundaberg and all of the nematode studies. Other research, not part of SYDJV, was also funded by SIRP.
