8 P a ge 8 Making Better Fertiliser Decisions for Cropping Systems in Australia: an overview Snippet from article by Simon D. Speirs et al In , Australian grain crops were planted across 24 Mha (Fig. 1; production area for major crop species shown in Table 1), a 12% increase in crop production area compared with statistics (ABARES 2012). During 2011, Australia used 1099 kt of fertiliser nitrogen (N), 384 kt of phosphorus (P), and 149 kt of potassium (K) across all agricultural industries (ABARES 2012). This represented a 26% decrease in total P and K consumption, and a 6% increase in N consumption since There is evidence that the change in P and K fertiliser usage is mainly related to reduced application of superphosphate to pastures and a reduction in the area of sugarcane (Saccharum officinarum) where K fertiliser is used (C. Dowling, pers. comm.). However, in grain production systems there has also been a reduction in P use of ~15% (C. Walker, pers. comm.). This is expected to relate to often-sufficient soil P reserves (e.g. NLWRA 2001; Weaver and Wong 2011). No data were reported in ABARES (2012) for sulfur (S), which has traditionally been supplied to grain crops as a coconstituent of fertiliser P (superphosphate 8.8% P, 11% S) or N (ammonium sulfate 21%N, 24%S), or through gypsum (calcium sulfate 18% S) applications. Despite the importance of nutrients supplied through fertiliser, soil testing is a tool used in less than half of the fertiliser decisions made for grain production in Australia. Approximately soil samples are analysed for agricultural production and research annually by the eight largest commercial soil testing laboratories, representing >95% of all analyses conducted in Australia. Edwards et al. (2012) found that two-thirds of a surveyed group of 1300 grain producers (there are ~ grain-producing farms in Australia; ABS 2012) would routinely use soil testing. Of those routinely using soil testing, half to three-quarters undertook soil testing in a given field at least once every 3 years as per current recommendations (e.g. Weaver and Wong 2011), and half of the reported crop area managed by survey participants was informed by soil testing. This variable use of soil testing as part of fertiliser decisions broadly reflects the individual decision frameworks used by grain growers and their advisors. It also reflects different levels of confidence and competence among some members of these groups. This is specifically attributed to: (i) a limited understanding of nutrient requirements and contributory soil processes including soil sampling; (ii) poor producer and advisor confidence in the ability of analytical methods to adequately predict plant nutrient requirements; (iii) belief that analytical results vary between laboratories; and (iv) a view that collecting soil samples is time-consuming, expensive, and unprofitable. Irrespective of reasoning, choosing not to soil test on a regular or semi-regular basis (e.g. sampling for analysis once every 3 years) ignores an important and relatively inexpensive source of information that

Much of this process is driven by grain producers and advisors, who collect soil samples, interpret soil test results, and make fertiliser decisions for farm systems. Two challenges are outside the domain of the grain producer and/or advisor: laboratory analysis and proficiency, and the soil test crop response calibration data used to aid soil test interpretation.
10 P a ge 10 In Australia, soil and plant inter-laboratory proficiency programs are conducted by the Australasian Soil and Plant Analysis Council (ASPAC), who provide certification to laboratories for specified analytical methods. The use of an ASPAC-certified laboratory for specific methods is aimed at providing grain growers and their advisors with greater assurance about the reliability of analytical results. Guidelines for soil test interpretation for N, P, K, and S are provided by Peverill et al. (1999); they collated a record of the available soil test criteria for different crops and pastures in Soil Analysis: an interpretation manual. While an important resource, it does not allow distillation based on specific criteria and can be difficult to apply in the field. Since this publication, the ability to manage large datasets has progressed substantially. The first national collaborative effort to collate historical fertiliser trials was undertaken in a project named Making Better Fertiliser Decisions for Grazed Pastures in Australia (Gourley et al. 2007). This was followed with an investment by the Grains Research and Development Corporation (GRDC) into two projects: Feasibility Study to a National Approach to the Collation of Fertiliser Response Trials ( ), and Making Better Fertiliser Decisions in WA Cropping Systems ( ). Both projects addressed the macronutrients N, P, K, and S as the major nutrients for Australian grain producers. Following the feasibility study, a collaborative national team of researchers and fertiliser industry representatives was engaged by the GRDC to undertake the project Making Better Fertiliser Decisions for Cropping Systems in Australia (BFDC). The combined datasets from BFDC and Making Better Fertiliser Decisions in WA Cropping Systems are reported in this overview paper. Objectives The two objectives of the BFDC project were to review current fertiliser response trials for the interpretation of N, P, K, and S soil tests, and to provide the grains industry with increased certainty and confidence by establishing a benchmark database for N, P, K, and S soil test interpretations. These objectives were met by: (i) collating all available and statistically valid N, P, K, and S crop response data for cereals, oilseeds, and pulses into a single BFDC National Database; (ii) developing a live online tool (the BFDC Interrogator) to provide fertiliser companies, agribusiness, consultants, and researchers with the capacity to derive critical soil test criteria; and (iii) delivery of a training package aimed at ensuring that users of the BFDC Interrogator possessed the knowledge and skills to develop and use critical soil test criteria. Collating historical soil test crop response experiments Soil test crop response calibration experiments have been conducted for N, P, K, and S fertiliser use, predominantly in wheat, by the grains and fertiliser industries since the late 1950s. There has also been substantial evolution of Australian farming systems during the last 30 years (e.g. increasing intensity of cropping, a reduced reliance on legume-based pastures, increased use of minimum or no-tillage, and the introduction of variablerate technology),
11 P a ge 11 and the relevance of historic data has been questioned. To address these challenges all available data needed to be collated to a single repository. Within these challenges, there has also been increasing recognition that (i) discrete datasets (and individual experiment reports) from experiments conducted years ago are difficult to access or no longer available (e.g. Taylor et al. 1974, 1978), (ii) the retirement of pivotal soil and plant nutrition scientists is leading to a loss of substantial knowledge and experience, and (iii) data storage and agricultural communication methods are changing through increased focus towards online approaches. In the current BFDC study, all soil test crop response data that could be unearthed were collated to the BFDC National Database (Watmuff et al. 2013). Calibration relationships The BFDC Interrogator (Watmuff et al. 2013), an interactive ( live ) online tool, was developed to enable researchers and advisors in the grains and fertiliser industries to derive soil test crop response calibration relationships based on experiments held in the BFDC National Database. Using the BFDC Interrogator, calibration criteria can be obtained for a specified nutrient (N, P, K, or S), based on selected data filters (e.g. crop type, grain yield, region, soil type, soil test method, and soil sampling depth), by establishing the relationship between percentage relative yield [%RY = (Y0/Ymax)100)] and soil test value for the selected nutrient of interest.
12 P a ge 12 Uptake by the grains and fertiliser industries The BFDC Interrogator was established to permit analysis of the soil test crop response trial data used for determining the best N, P, K, and S soil test interpretations to underpin fertiliser recommendations in Australia. The primary target audience for these products was key people in agribusiness and the fertiliser industry (particularly those companies with a DSS for deriving nutrient recommendations) as well as the research community. The BFDC Interrogator was not built as a DSS for grain producers per se. BFDC National Database a legacy The BFDC National Database represents a legacy that other agricultural fields could choose to replicate: many of the researchers who conducted much of the soil test crop response experimental work in Australia are now retired; many of the trial data, particularly for states other than Western Australia, were obtained between 1960 and 1990; few organisations, particularly government agencies, have maintained inventories of their soil test crop response experiments; and there is demand for greater accountability among those applying fertiliser nutrients (i.e. market accreditation programs and current government policies). Establishing the BFDC National Database of soil test crop response experiments is a major development for crop nutrition in Australia, particularly when coupled with the online BFDC Interrogator interface. Fertcare, the fertiliser industry s stewardship program, recognises the database as the national baseline standard to underpin soil test interpretation as part of the fertiliser recommendations made by agricultural advisors to Australian grain farmers.
13 P a ge 13 Using Conservation Agriculture to improve water use efficiency in wheat crops on the Branson farm in South Australia Branson M The 1200 ha Branson farm is located between Stockport and Giles Corner in the lower north of South Australia. Annual rainfall is 475mm which predominantly falls in the winter months; growing season rainfall (GSR) is 350mm which falls from April to October. As such, the farm is in the high rainfall zone for cropping in South Australia. The Bransons have been early adopters of new technology throughout the generations. The farm was an early adopter of superphosphate, the ley farming system, which included the growing of pasture legumes, and improved weed control with herbicides. When the present owner/manager and author took over the farm in 1990, grain legumes were introduced into the rotation and minimum tillage was adopted. In 1997, yield monitoring was introduced, and following the purchase of new sowing equipment, all crops have been sown with No-Till since In 2004 with the purchase of very accurate GPS equipment (RTK 2cm), Controlled Traffic (CT) was introduced to the farm with all major farm machinery being driven using autosteer technology. In 2005, the author won and completed a Nuffield Scholarship where he studied overseas for 18 weeks looking at Conservation and Precision Agriculture. In 2006 a handheld Greenseeker was purchased and used with Nitrogen Rich strips (Raun et al., 2002) to fine-tune Nitrogen (N) applications. Also in 2006, a full Precision Agriculture (PA) fertilising program was developed with all Phosphorus (P) based fertilisers being Variable Rate (VR) applied. In 2010, a set of CropSpec sensors were purchased which have enabled the introduction of VR N application. The Branson farm is now one of the leading farms in Australia in the adoption of new cropping technologies into the farming system. The author believes that improving soil health and structure holds the key to improving water use efficiency (WUE) which leads to improved farm profits and benefits the farm environment. He has designed his farming system by using worlds best farming practice to achieve this. This paper discusses the achievements made to date on the Branson farm in increasing the WUE of wheat crops through the adoption of new cropping technologies. Two periods are of particular interest in this paper. The first, from 1990 to 2001, was the period in which the farming system changed to include growing grain legumes and the introduction of N based fertilisers. The second, from 2002 to 2010, was the period in which new cropping
14 P a ge 14 technologies, including No-Till, CT and PA techniques, were introduced to the farming system. Materials and Methods From numerous benchmarking exercises, wheat yield has been identified as a key driver of farm profitability on the Branson farm. A way of mapping wheat yield gains over time is to use the actual yields achieved divided by the French and Schultz potential yield calculation (French and Schultz, 1984). The result reflects the percentage of potential wheat yield obtained given the actual growing season rainfall, the key driver to wheat yield in rainfed cropping systems. The French and Schultz potential yield calculation determines attainable wheat grain yield per unit of water use (i.e. 20kg grain/ha/mm). The calculation requires the GSR minus soil water evaporation (assumed by the model to be 110mm) to be multiplied by 20kg/ha. Here, GSR was calculated from the actual April to October rainfall plus half the rainfall in the months of March and November, and the value obtained by dividing the actual yield by the potential yield referred to as 'percent potential yield'. Five year rolling average yields and percent potential yields were calculated and trend lines fitted to the data using simple linear regression in MS Excel. Results and Discussion Percent potential yield on the Branson farm increased from 64% in 1990 to 91% in Over the same period, potential yield decreased from 5.1 to 4.85 t/ha due to a decline in GSR. The improvement in percent potential yield can therefore be attributed to improved WUE associated with changes to the farming system. Of note is the fact that the gains in WUE achieved on the Branson farm greatly exceed the small increase achieved in the district as a whole, which on average sits at 50 to 60% percent potential yield (Stephens, et al., 2011). No-Till has been adopted by the leading farmers in the district who are experiencing gains, but CT, PA and other new technologies are mostly not adopted. Over the years from 1990 to 2001, the farm rotation changed to include the cereal break crops of field peas and faba beans, and the oilseed crop of canola with the aim of reducing cereal root diseases such as CCN, Rhizoctonia, and Haydie. During the same period, N based fertilisers were introduced to improve crop nutrition, and stubble retention was enforced. Most of the leading farmers in the district adopted these farming system changes, some faster than others. Analysis of this period shows that the percent potential yield trend line from smoothed 5 year averages increased from 66% ( ) to 81% ( ). This is equivalent to a 1.1% annual increase in WUE. In the period from 2002 to the present, No-Till, application of additional animal manures, growing more high carbon crops and the continuation of stubble retention has led to an improvement in the soil structure. In addition, more effective nutrient cycling, especially of N, seems to be occurring with less N needing to be applied for the same outputs.
15 P a ge 15 Both these gains are consistent with results obtained overseas (Reicosky, 2005; Lafond et al., 2008) in which improvements in soil structure and nutrient cycling have been attributed to extra carbon being added to the soil using the above farming practices; CT has decreased soil compaction (Webb et al., 2004). Overall, the improvement in soil structure from the above farming system changes has led to more water and nutrients being available to the crop to grow and produce grain. Thus percent potential wheat yields have increased at a rate of 2% per year for the period to and now sit at 91%. This is equivalent to an annual increase in WUE of 0.9% following the adoption of new cropping technologies in the farming system if the gains in the first period are maintained, but could be more if they had slowed. It is concluded that the adoption of Conservation Agriculture and PA has led to increased wheat yields on the Branson farm well in excess of the district average. It has also led to an improvement in farm profits and the farming environment.
