Efficient Irrigation Solutions for Sustainable Agriculture Practices

1. Climate Change Workshop 2008 Watering the Next Century: Sustaining a Resource for the Future Bob Snoozy Senior Vice President Sales and Marketing Lindsay Corporation

3. The Secret Behind Crop Circles

4. Challenges for Irrigators • Use less Water • Use Less Energy • Do it with less Labor • Do it Environmentally Friendly • Do it Economically

5. 200,000 in the US45,000in Nebraska

6. Efficient Irrigation is a Global Concern

7. Nadec, Hail Hadco, Hail Kingdom of Saudi Arabia – 500 Lindsay/Zimmatic pivots

8. Less Water

9. Yesterday’s

10. Today’s

11. S.L.O.G. Sprinklers Located On the Ground

12. APPLICATION EFFICIENCY WIND RESISTANCE RATING Spray losses - 3-5% for 3-6 ft height 10% on top of pipe can double as wind speed increases from 0-5 mph to 5-10 mph Brad King, U of ID & Dennis Kincaid, USDA-ARS Application Eff. – 85% for Low-Angle Impacts 92% at 5 ft height 1 inch application on mature corn, NebGuide G97-1328-A

13. What’s a 7% water savings worth? 2,500 Hrs/Yr (avg.) x 7% = 175 Hrs (less run time) Assume 50 HP for pump and pivot Cost per HP-Hr = $.07/kilowatt-hr ÷ 1.18 HP-Hr/kilowatt-hr = $.06 / HP-hr $ Savings = $.06/HP-Hr x 50 HP x 175 Hrs = $525 / yr $5,250 over 10 years ($10,500 over 20) What is 5,250 (or 10,500) fewer hours on the pivot & well worth? (drive train, contactors, micro-switches, structure)

14. Less Pressure = Less Energy

15. $ Savings with Low Pressure Savings What’s a 30 psi pressure savings worth? (from 50 psi at end to 20) HP Savings = (800 gpm x 30 psi x 2.31 ft/psi) ÷ (3960 x 75%) = 19 HP (less 2 HP for booster pump) = 17 HP $ Savings = $.06/HP-Hr x 17 HP x 2,500 Hrs = $2,550 / yr $25,500 over 10 years ($51,000 over 20) Don’t forget to add the efficiency gains too (if you add drops)!

16. Less Labor Manage from Anywhere • Offers peace of mind • Simple controls • Voice acknowledgements and alarms • Irrigation systems proactively alarm on unscheduled shutdowns Voice Command

17. New Product Development

18. Do it Environmentally Friendly Injectors Provide Versatile Applications • Fungicides • Pesticides • Herbicides • Gypsum • Liquid PAM • pH control

19. Moisture Monitoring Benefits • Increase profit with improved potential of crop yield and quality • Save money by optimizing water, fertilizer and energy use • Reduce wasteful leaching by targeting water and fertilizer to the root zone • Sustain best management practices

20. Monitor your field’s Climate • Irrigation accumulation • Evapotranspiration • Growing degree days • Pest/disease models • Keep records • Much more..

21. Controlling Costs

22. Precision Application

23. System of the Future In-Field Irrigation Controls Record Keeping Remote Irrigation Control Integrated Systems Nutrient Management Resource & Performance Management Soil Moisture Monitoring Pest & Disease Management Micro “in-field” Climate Monitoring

24. Tools • Less expensive monitors • Agriculture Economy to support efficiency expenses.
