    • The value of land underpins farming businesses and rural communities.
    • Farmland values have been increasing over the same time period where significant gains have been made in yields.

    • Work with nature and look after insecticide tools through strategic (not indiscriminate) insecticide use.
    • Russian wheat aphid (RWA) is a significant new pest of Australian cereal crops.
    • The known distribution of RWA is still limited to parts of SA and VIC. Suspect aphids found outside of these areas should be reported to biosecurity authorities in all State jurisdictions.
    • RWA is a manageable pest, with a combination of effective cultural, chemical, biological and (longer-term) plant resistance controls available.

    • Nodulation and shoot dry matter in medics is depressed by poor phosphorus (P) nutrition and in-crop application of certain herbicides.
    • Applying P when establishing a medic pasture boosts shoot and root dry matter, improves root health and improves nitrogen (N) fixation.
    • The timing of application of certain herbicides can have an effect on maximum shoot dry matter.
    • High soil N levels can reduce nodulation in medic pastures.

    • Herbicide performance will vary seasonally due to soil moisture levels, rainfall pattern post application, timing of weed germination, position and number of weed seeds in the profile, etc. Understanding how the various herbicides work can reduce the likelihood of failures.
    • In different stubble management systems the activity and resulting weed control of specific herbicides will be influenced by a range of factors including the solubility index (movement through the soil profile with rainfall events) of that herbicide. Soil texture, organic matter and soil chemical properties can affect chemical movement and availability in the soil profile.
    • Herbicides are only one tool for weed control; always adopt an integrated weed control package that includes non-chemical control, and where possible, consecutive seasons of total weed control.
    • Consider the whole farming system when making chemical decisions as the impact may last for several seasons (eg. effects on medic germination and medic seed bank).
    • In the 2015 herbicide efficacy trial, the drier start to the season and low soil moisture resulted in lower herbicide efficacy and less chemical damage than expected across all the treatments.

    • Change is inevitable the sooner we embrace it the sooner we can profit from it.
    • All change is not necessarily good so we need good filtering processes.
    • Your perception is your reality and the basis of your decisions. Make sure it is an accurate one.
    • Choose your attitude; it determines the quality of the outcome.
    • Are you suffering a farming addiction, if so understand how to address it?
    • Understand the importance of the stimulus-response reward cycle.
    • Time is your greatest resource, understand its importance and use it efficiently.

    • Don’t change for the sake of change.
    • Thoroughly evaluate each enterprise’s contribution to the business as a whole.
    • Drill deeper than gross margin analysis for a more accurate picture.
    • Look to promote synergies within and between enterprises.
    • Avoid antagonism within or between enterprises.

    • Diversity of applications is welcome, however replicating each others’ success doesn’t work when the data structures are different.
    • Precision farming data needs an industry-wide solution for seamlessness and security.

    • Bentleg openers combined with bevel edge features mostly cancel soil throw and maximise furrow backfill. They offer an unprecedented ability for high speed, low soil throw no-till tine seeders.
    • Latest research on integrating bentleg openers into tine seeding systems showed the potential to adequately control seed and fertiliser placement at speeds of up to 14km/h, and establish wheat crops similarly or better than common knife point technology.
    • Residue handling with an integrated residue guard design suggests similar capacity to knife point openers fitted on C-style shanks, and potential benefits from straw clumps (mostly free of soil) having less impact on hindering seedling emergence.

    • In 2016 additional cereal hay has been welcomed by buyers and absorbed into the market.
    • The scale of pasture hay production has a massive impact on cereal hay demand.
    • The dairy sector is likely to avoid buying hay in 2017 and a broad range of buyers is advised.
    • Export hay should be in the marketing mix as it should be a high paying market in 2017.
    • The Chinese glut of dairy products should reduce this year, supporting continued growth in hay imports of oaten hay from Australia.
