Alfalfa’s water requirements are comparable to that of crops like spinach, wheat, almonds or corn, but its long growing season and high acreage make it one of the most-water-intensive crops. It takes about 4 to 6 inches (10 to 15 cm) of supplemental irrigation to produce each ton (11 to 17 cm per ton) of dry hay.
Senninger® Sprinklers: Precision Irrigation for Water Efficiency
Senninger® sprinklers are engineered to optimize agricultural irrigation solutions by minimizing water loss due to wind-drift and evaporation. Their uniform distribution pattern ensures consistent soil moisture, promoting efficient root zone coverage that enhances plant health and productivity. Whether used in an alfalfa irrigation system or other crop applications, Senninger® sprinklers help farmers maximize water efficiency while improving yields.
i-Wob®2
The i-Wob®2 delivers the most uniform water distribution of any pivot applicator available today. Its protective shroud shields the sprinkler’s wear surface from grit, UV exposure, and splashing from adjacent sprinklers—ensuring longevity and consistent performance. By maintaining low operating pressures, the i-Wob®2 helps reduce energy costs while delivering precise irrigation coverage, making it an excellent choice for alfalfa irrigation methods and other demanding crop applications.
LDN® LEPA
The LDN® LEPA (Low Energy Precision Application) bubblers are designed to achieve 95% to 98% water efficiency, ensuring nearly all the pumped water reaches the crop’s root zone. Installed between 8 to 18 inches (20 to 46 cm) above the ground, these sprinklers help prevent evaporation loss and wind drift—critical factors in alfalfa irrigation requirements. The LDN® LEPA system enhances soil moisture retention, reducing unnecessary water use while promoting deep-root growth for resilient crops.
LDN® Spray
The LDN® (Low Drift Nozzle) provides growers with multiple irrigation options while allowing precise control over the sprinkler’s distribution pattern and trajectory. Its streamlined design enables it to navigate through tall crops while maintaining optimal water efficiency. Whether used in irrigating alfalfa fields or other row crops, the LDN® ensures even coverage and reduced water waste, helping farmers meet alfalfa water use demands effectively.
Xi-Wob™
The Xi-Wob™ brings the renowned instantaneous, uniform water distribution of the i-Wob®2 to semi-rigid PE and steel drops. Designed for low-pressure operation, it delivers a wide coverage area with low application intensity—ideal for preserving soil structure and minimizing runoff. Whether incorporated into an alfalfa irrigation system or other agricultural irrigation solutions, the Xi-Wob™ enhances irrigation efficiency while reducing energy consumption.
Control Your Pressure
Every system experiences pressure fluctuations, resulting in unwanted flow deviations and over and under-watering. Regulators maintain a constant preset outlet pressure with varying inlet pressures, which alleviates pressure differences that can cause an applicator’s area of coverage to change.

"It's all about efficiency. We found out real quick that if we got more water on the ground, we can cut back on the amount of water we were using. We think we can cut pumping expenses, save water, and at the same time we're growing more crop. And all the water was going to the ground.” - John Maurer

"We use a lot of Close Spacing in this area -- probably 99% of everything that I sell with sprinklers is Close Spacing. 30-inch spacing will come out traditionally between 98 and 99% uniformity and distribution of water applied. You can't get that with the sprinkler that's ten feet apart and five feet off the ground."
