Wheat and canola tools and resources for Agronomists

This paper provides agronomists with a series of objectives, references and  tools.

Two key production timings for agronomists to focus on are Pre - Crop and In - crop. Pre - Crop tends to be focussed around the information and tools needed to plan and strategize the year ahead.  In - crop is using the information from monitoring and diagnostics to establish “Why is this so?” and “where are we going to next?”

Pre Crop

Cropping Operation Management

Harvest and stubble management

Objectives:

  • Stubble height requirements for seeding
  • Stubble height and windrow requirements for windrow burning
  • Stubble height and spread requirements for effective pre-emergent application
  • Conditions required for windrow burning
  • The importance of stubble management in conservation systems.

Seeding strategies

Objectives:

  • Identify the opportunities and risks associated with seeding strategies.
  • Yield prophet (APSIM model) can provide a good guide to risks associated with planned sowing date in selected locations. Must be a registered user.

Nutrition management

Objectives:

  • Understand correct testing procedures for soil water, nutrient and disease.
  • Agronomist will need to be Predicta B accredited.
  • Basic interpretation of results and how to use in nutrient strategies.
  • What’s SBU? Safe rates of nitrogen  used at seeding?
  • Use relevant apps like CSIRO “Soil Mapp” to characterise soil types.
  • Using models like “Yield Prophet”or WA’s new award winning “iPaddock” or the Climate Kelpie link to yield and N calculators in predicting yield.
  • Formulate nitrogen and sulphur strategies based on crop type, yield prediction, adversity to risk, gut feel and farm operational risks (ability to top-dress on time).
  • Conduct nutrient audits from crop removal values.
  • Calculate the cost of applying fertiliser.
