Setup of the workshop

• Introduction
• New technology
• Accurate positioning and auto guidance
• Sensors, cameras and imaging software
• Site specific action
• Increasing Efficacy and Automation in Mechanical
  Weed Control
• Site specific Herbicide Application (practical
  case)
• Discussion priorities fields of innovation

3
Development in farming and farm mechanization
relevant to precision farming

• Threats
• Farm size will double next 10 years
• Bigger machines
• Increased Scale and Precision seem contradictory
  subjects
• Chances
• Technical Innovations
• Knowledge enables better advices
• Automation of the production proces

4
Precision farming fun or fundament

• Positioning and Guidance (within reach of
  farmers)
• Sensing (Remote sensing and sensors and cameras
  mounted on agro machinery can identify variations
  in vegetation)
• A small group of Farmers have high expectations
• Will this new technology help weed control?

5
Accurate Positioning and Auto Guidance

• Satelites and accurate positioning
• Mapping crop position and weed occurrence
• Increasing working width
• Auto guidance and robotization

6
GPS accuracy
Consumers GPS 5-15m
GPS Egnos 0.5 1.5 m
DGPS 0.1 0.5 m
RTK fixed 0.005 0.02cm
7
Positioning Crop and Weed

• Possibilities with RTK GPS and GIS
• Uniform, regular spacing of plant rows and plants
  
• Auto guiding machinery
• Increasing working width of hoeing equipment
• Mapping position of crop rows
• Mapping weed spots

8
Mechanical weed control

• More accurate guidance of intrarow weeders
• Working width not limited by sowing and planting

Effects

• Decreasing labor costs
• Decreasing fuel costs
• Lower risk of crop damage
• Better weed control
• Increasing machine price
• Costs of installing Accurate Positioning system

11
Where are promising possibilities robotisation
12
Concentrate on crops or specific weed problems

• Farmers indicate
• Site specific only to improve crop quality
• Volunteer potatoes in different crops
• Perannual weeds weed mapping and mechanical or
  chemical herbicide application

13
Cameras and imaging software

• Ecodan, Robocrop etc. row identification and
  machine guidance
• Increased hoeing width
• improved guidance of finger-/ torsion- weeders
• Better weed control
• Individual crop plant identification and
  intrarow weeding

Necessary Improvements spraying equipment

• Reduction reaction time sprayer 30 sec tot 3 sec
• Site specific sensing a sensor / 3 meters
• Decrease resolution SSA from 240 m2 to lt10 m2
