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

Spray losses - 3-5% for 3-6 ft height

can double as wind speed increases from 0-5 mph to 5-10 mph

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

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

Less Labor Manage from Anywhere

• Offers peace of mind• Simple controls• Voice

acknowledgements and alarms

• Irrigation systems proactively alarm on unscheduled shutdowns

Voice Command

New Product Development

Do it Environmentally Friendly

Injectors Provide Versatile Applications

• Fungicides• Pesticides• Herbicides• Gypsum• Liquid PAM• pH control

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

Monitor your field’s Climate

• Irrigation accumulation

• Evapotranspiration• Growing degree days• Pest/disease models• Keep records• Much more..
