The Secret Behind Crop Circles

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

200,000 in the US 45,000 in Nebraska

Efficient Irrigation is a Global Concern

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

Less Water

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

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 G A APPLICATION EFFICIENCY

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)

Less Pressure = Less Energy

Low Pressure Sprinkler Technology.

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)! $ Savings with Low Pressure Savings
