The outputs of this and previous projects confirm the ability of CQ grain growers to produce more grain from less water using an opportunity cropping strategy during a decade of low rainfall years (2000-2009) and still maintain a profitable industry... This group of activities showed that the technologies assessed in the project were not 'grower friendly', and that they needed a high level of expertise for successful use and adoption... Cropping frequency An assessment of cropping sequences over 10 years on the Moonggoo and Kilmore case study farms examined the potential for increasing the cropping frequency in CQ as a means of improving the profitability of grain production...

Previous cereal research work in northern NSW has focussed on in-crop nitrogen application as a "top-up" treatment with the greater proportion of N being applied to the seedbed... Work in 2006 and 2007 showed significant differences in canopy structure when nitrogen was delayed until stem elongation (GS31) but in both years that was no significant increase in grain yield compared to when N was applied at sowing... Figure 3: Influence of split N applications on grain yield from early and main sown EGA Gregory For the later sowing, results are very similar to those in 2006 and 2007 with split applied or N applied at GS31 maintaining grain yields but limited significant yield response compared to the seedbed N treatment (figure 3)...

There is a need to improve N management in Australia's grain production systems, both for economic and environmental reasons... This project aims to develop a compendium (knowledge document) plus interactive excel-based decision support (DS) software ('NBudget') for improving knowledge and management of soil, fertiliser and legume N. The N management package is targeted at farmers and advisers... We also propose to promote the use of the N management package through workshops and GRDC Updates...

The N management package is targeted at farmers and advisers... Making decisions about how much fertiliser N to apply to a particular paddock is set to be more challenging than usual after the wet 2010 season and early part of the 2010-11 summer fallow...

Each year, growers in the northern grains belt make decisions about the amount of fertiliser nitrogen (N) they are going to apply to approximately four million hectares of paddock, with the vast majority of decisions made without the benefit of soil testing... From the validation work that has been done, it is clear that 'NBudget' can assist growers and advisers to fine tune N management decisions provided they have adequate records from the previous season, i.e. prior grain yields and proteins and fertiliser N inputs for the particular paddock... The 'NBudget' algorithms are also incorporated into CropChooser on the original CropMate website, thereby providing potential users with a tool to compare the economics of various cropping options (i.e. gross margin analyses) in which N and biological effects have been valued and the value attached to the crop, rather than the cost of production of the following crop...

New era of collaboration to address N knowledge gaps.. A first-of-its-kind forum in Bundoora, Victoria, driven by industry and facilitated by the Grains Research and Development Corporation (GRDC), has identified a range of knowledge gaps which are ultimately impacting on crop yield and grower profit... "The goal of this first forum was to enable key stakeholders to contribute to designing a way forward to address the gaps identified in N management RD&E and how they may be involved in the solution," Mr Rice said...

"The Australian grains RD&E sector is constrained by available resources, finite dollars to invest and fewer people operating over vast distances, so it is imperative that collaboration needs to be the hallmark of the way we deliver RD&E," Mr Rice said... "We need to create more accessible opportunities for growers, advisers and researchers to have input into the identification, design and delivery of RD&E that is going to have the most impact on-farm, and the nitrogen management forum is part of that approach... "The goal of this first forum was to enable key stakeholders to contribute to designing a way forward to address the gaps identified in N management RD&E and how they may be involved in the solution," Mr Rice said...

To be facilitated by the Grains Research and Development Corporation (GRDC) on behalf of stakeholders, the forum will appraise past and current investments in research, development and extension (RD&E) related to N management, leading to identification of existing and likely future gaps in knowledge and adoption... "It is critical that all relevant industry stakeholders - including existing and potential RD&E partners - come together to discuss what we know and what is unknown so that a targeted, strategic and collaborative approach to future investments can be planned and undertaken to deliver solutions to growers.".. "The GRDC and its research partners have a responsibility to support grain growers in their quest to boost productivity and profitability, and this initiative is a crucial first step in recognising what additional work needs to be done in an area that has such an impact on growers' returns."..
