Shifting Perceptions


Field traffic is usually Uncontrolled

Understanding Soil Health

Sustainable Food Production


Machine Guidance “Auto-steer”

Radio

Rover

Base station


GPS Guidance for Inter row sowing


Shielded spraying using 40% less chemical


50% banding

Why we need precision!50% less chemical

Traffic

Farming

11% for machinery

89% for crops

  • Improve Soil Health

  • Increase Production

  • Build resilience against drought

  • Reduce fuel use by 50%


CORS Networks


Connectivity in Cab

  • Remote diagnostic analysis

  • Rapid data transfer - cloud

  • Inter-vehicle communication

  • Mobile office, e-commerce etc…


Wireless Vehicle Control


Why is this important?


Point Data


RTK derived topography map


Ponding Analysis


Plant Biomass Mapping


High Biomass

Low Biomass


Not always fun???


“NDVI Farm Maps are a great resource to identify problem areas

not necessarily seen by the naked eye”


Weed Seekers


Soil Data Collection

Accurate Job Data Records

  • All data is stored in an intuitive explorer view, in a hierarchy system with the following levels:

  • Project

    • Client

      • Farm

        • Paddock

          • Crop

            • Operation

On-Farm Research


SMART Farming

  • Machine GPS guidance

  • Information Rich

  • Precise input placement

  • Consistent spatial footprint

  • Accurate field operations mapping

  • Max production with less inputs

  • Economic, Environmental, Social
