Irrigation Solutions for Alfalfa Producers

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 are designed to save water by combating wind-drift and evaporation. Their uniform distribution pattern helps achieve a more uniform root zone coverage, which results in higher moisture levels.

i-Wob®2

The i-Wob®2 provides the most uniform water distribution compared to any pivot applicator on the market. Its protective shroud guards the sprinkler’s wear surface from the splashing of adjacent sprinklers, grit, and direct UV damage.

LDN® LEPA

LDN® LEPA bubblers help ensure 95% to 98% of water pumped gets to the crop’s root zone. These sprinklers are installed 8 to 18 inches (20 to 46 cm) above the ground to combat wind-drift and prevent evaporation loss.

LDN® Spray

The LDN® (Low Drift Nozzle) offers growers multiple ways to irrigate and control of the sprinkler’s distribution pattern and trajectory. Its streamlined body can handle the rigors of traveling through tall crops.

Xi-Wob™

The Xi-Wob™ takes the instantaneous, uniform distribution pattern popularized by the i-Wob®2 to semi-rigid PE and steel drops. It provides the same low operating pressure, wide area of coverage, and low application intensity as the i-Wob2.

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.

Senninger® black and white pressure regulators are renowned for their accuracy, durability, and ability to maintain the overall efficiency of an irrigation system.

"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."
