  1. 1. Sensing tool in advisory service Herman Krebbers Mechanisation and precision farming
  2. 2. Delphy (former DLV Plant) • Independend advisory service in plant production • More then 200 employees, 150 national, 50 abroad • 90 % individual advice to farmers on contract base • Planning fertilizer, crop protection,… • Field inspection and actual advice on optimizing crop production results
  3. 3. Smart Farming large potential • Variety research: 15-20 higher yield then practice • Best farmers 5-15 % better then average • Optimal use of yield potential fields
  4. 4. Yield measurement • Delphy mobile weighing system • Farmers aware of differences and potential • Benchmark 4 Perceelnaam Ha ton/ha Droge stof % Droge stof / ha Perceel Overmars 2,4 56,6 30,52% 17,28 Perceel Schoterman 3,06 55,5 30,82% 17,11 Perceel Heideman 3,24 51,7 30,26% 15,66 Perceel Noorder- Koeslag 2,81 42,0 32,20% 13,53
  5. 5. Smart Farming large potential • Measure yield potential own fields, benchmark, yield measurement • Measure most important parameters • Knowledge how to estimate data and decide about moment of action and dosages • Automated technical action in the field
  6. 6. Projects and farmers experience • 2011-now, 5 large projects • Network 5 regions, 250 farmer participants • Using al types of sensing technology • Exchange experiences and demands for improvements ! Use research data, and farm data ! Focus on direct practical use and benefits of farmers and advisers
  7. 7. Primary needs Farmers • Quantative data growth zones and fields, overview • Related to inputs; actual data! • Related to soil parameters • Direct advice on actions to improve, task maps Advisers • Improve quality of advice: data at farm and field • Easy zone specific field inspection and advice • Priority list and alert system first fields to go for inspection and action
  8. 8. Crop sensing, demands • Show important differences crop growth • Full field cover in high resolution • Available at right moment to take action: several moments, - flexible to weather… - flexible to crop growth - flexible to regulations • Easy to handle data and graphs • Low costs
  9. 9. Spectral sensing systems • Satellite - large capacity, cheap, - not reliable in actual data (clouds) • Sensors - Easy to use, automatic on biomass/nitrogen uptake - High investment, only narrow tracks measured
  10. 10. Spectral sensing systems • Drone - flexible, at right moment, high resolution - tough regulations, capacity limited, costs • Airborne - high resolution, high quality - high capacity - relative low cost
  11. 11. Sensing with spectral drone Source: Agrofuture, Groningen Fertilizer levels clear visible
  12. 12. Sensing with airborne spectral • Details zones and fertilizer levels clear visible • On field trials 0-100-140-200 • Determine optimals after yield sampling • Faults seeding, spraying fertilizer visible
  13. 13. Different moments of sensing essential Potato field: Analyse causes and how to act? 23 juni 3 juli 18 juli
  14. 14. Zone – fieldinspection - action 14 Spot navigationCrop scanning Soil inspection Zone specific action
  15. 15. Conclusions 1 • Crop sensing large potential zone based optimizing yield en efficiency of inputs • Many fields rather small differences within fields => field action instead of zone action • Smart Farming now often technology driven. Needs to increase crop management driven • Very often soil structure, moisture, diceases more determinative then low nitrogen levels 15
  16. 16. Conclusions 2 • Drone sensing. Good potential, quick development outside agriculture, needs organizing • Airborne sensing good potential in full field sensing , quality of data and costs • Advice on dosages based on sensing to check in research and farm/field level needs agronomic knowledge crop growth management • Automatic data collection and processing different parameters essential 16
