Row Crops

Why Sprinkler Irrigation?

Row-crop farming is an intensive practice that requires significant quantities of fertilizers and a stable water supply to ensure the highest quality yields as possible.

Irrigation plays a crucial role in meeting each crop’s specific water needs so that plants can absorb the nutrients they need throughout the growing season. An efficient irrigation system provides adequate moisture based on the plant’s phenological stage, soil characteristics and environmental conditions where row crops are grown.

Senninger® offers multiple pivot, linear, and solid set products designed to improve the efficiency of irrigation over row crops. Some of our spray nozzles are ideal for small-seeded crops germination. Other applicators are designed to deposit water straight down into furrows to prevent wind-drift and evaporative losses at very low pressures.


  • Outstanding Uniformity
    Uniform distribution pattern helps achieve a more uniform root zone coverage, which results in higher moisture levels.
  • Ideal Droplet Size
    Sprinklers distribute water in larger droplets resistant to wind-drift and evaporation loss.
  • Low Application Intensity
    Irrigating with low application intensity prevents run-off and overwatering, which could lead to weed invasion or disease proliferation.
  • Low Operating Pressures
    Lower operating pressures from 6 to 20 psi (0.41 to 1.38 bar) reduce energy costs.

    LEPA applicators gently deposit water 8 to 18 inches near the soil surface. They provide 20% more water to the soil than conventional spray nozzles.

    Flow Range: 0.27 - 18.35 gpm (61 - 4168 L/hr)

    Pressure Range: 6 - 15 psi
    (0.41 - 1.03 bar)

  • LDN Spray

    LDN pads deliver different spray patterns and droplet sizes. Multiple deflector pads can be used to divide a larger flow into more streams.

    Flow Range: 1.09 - 15.78 gpm (248 - 3584 L/hr)

    Pressure Range: 10 - 15 psi (0.69 - 1.03 bar)

  • Pressure Regulators

    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.

Success in the Field

Location: Bakersfield, California USA
Crop: Potatoes, Carrots, Garlic, Onions & Watermelons

Senninger’s LDN UP3 nozzles helped Bob Bender of Tasteful Selections in Bakersfield, California obtain the highest germination rates he’s seen in carrots grown in the valley.

Bender installed the LDN UP3 on his linear machines and found that they gave him the fine droplet size he needed to germinate his small-seeded crops. He is also using less water thanks to the high distribution uniformity of LDN UP3s.

“I'm constantly looking for land where I could put this linear system on with this type of nozzle package because it's definitely paid dividends for us here at Tasteful Selections,” Bender said. “I would recommend this for California production, especially for the amount of vegetables and the small-seeded products that are grown out here. I can't think of anything actually at this point that could improve what we're doing now.”
