  • 1. South Australian Murray Darling Basin NRM Board
    Ranges to River NRM - Community Science Forum
    Farming Sustainability & Technologies
  • 2. Farming to Potential How Precision Agriculture technologies are transforming farmsFelicity Turner
    Mannum 2011
  • 3. Introduction
    What is Precision Agriculture
    What are the different “PA” Technologies
    How are these technologies being utilised by farmers
  • 4. Definition of PA - GRDC
    ‘Information rich agriculture.
    The use of yield maps, other spatial information and input-control technologies to better match agronomy to paddock variability. The aims are to increase profit and improve environmental management.’
  • 5. Precision Agriculture
    Requires use of “new” technologies
    GPS (global positioning systems)
    Sensors (Yield, EM38, Biomass)
    Satellite or Aerial Imagery
    Information management tools (GIS)
    Assess and understand variations with “Ground-Truthing”
  • 6. PA – My take…..
    Agricultural Concept relying on the existence of in-field variability
    About doing;
    The right thing
    The right place
    The right way
    The right time
    Measuring variability
    Understanding variability
    Managing / Utilising variability
  • 7. Data Layers & the collection methods
    3 Important
  • 8. EM38
    Measure of soil conductivity
    Electrolyte concentrations (salts)
    Moisture content
    Soil Texture (WHC, PAW)
    Supported with soil coring to identify factors influencing EM38 readings
  • 9. Potential outcomes of EM38 maps
    Clay spreading/delving
    Creation of VR ameliorant maps
    Creation of potential management zones (if strongly linked to yield)
    Site identification for irrigation areas
    Combined with elevation data; site selection for moisture probes
    VR Irrigation
    Drainage & earthworks
    Template for soil coring / testing
  • 10. Sensors / Imagery
    Aerial / Satellite Imagery
    PCD (Plant Cell Density)
    Ground-based Sensors
    NIR & “Red-edge” Spectrum
  • 11. Sensors
    Needs to be groundtruthed
    Once groundtruthed, it can represent;
    Plant stands
    Plant vigour
    Plant height
    Crop Disease
    Nutrient Deficiencies
    Weed Infestations
  • 12. Yield Data
    Collected with farmers harvester
    Most difficult layer to obtain
    If you miss it, it’s gone
    Allows identification and accurate measurement of variability across a paddock
    Yield data easily converted to revenue, nutrient removal, water use etc.
    Only actual yield can be overlaid and used to calculate financial outcomes
