Senninger Irrigation


Innovative irrigation solutions from Senninger have led the industry since the company’s inception.  The Florida-based sprinkler manufacturer keeps an ongoing focus on enhancing irrigation practices by providing growers with reliable products that offer not only water productivity, but also water efficiency. The new Xcel-Wobbler UP3 TOP, LDN Bubbler Pad and the Shroud illustrate the company’s wide range of solutions designed to meet specific irrigation needs, from the top of the pipe to close to the crop.

Xcel-Wobbler® UP3® TOP

top_irrigation_xcelwobblerSenninger has expanded their patented Wobbler technology with a new top-of-pipe Xcel-Wobbler that uses the innovative UP3 easy-change nozzle.  The new Xcel-Wobbler UP3 TOP can be mounted along the entire length of the center pivot using nozzles from #6 through #26.

This sprinkler works at low pressure to save energy while delivering wind-resistant large droplets.  The product is cost-effective, as well. A sprinkler package with the Xcel-Wobbler UP3 TOP, the PSR pressure regulator, and a steel nipple can cost less than typical top-of-pipe solutions.

Xcel-Wobbler UP3 TOP provides a gentle rain-like application suitable for all soils and various terrains.  Consistent with Wobbler technology, it delivers an instantaneous application over a large area. This approach minimizes the impact of the sprinkler pattern and preserves soil structure and infiltration capabilities. It also helps prevent run-off and wheel rutting.

Close Spacing with LDN Bubbler Pads & LDN Shroud
Technological evolution is geared toward improving performance, providing specific solutions, and addressing challenging conditions.  One such irrigation technology started 30 years ago with a close partnership between Senninger and the researchers at the Texas A&M AgriLife Research & Extension Center, through which was developed the first Low Energy Precision Application (LEPA) sprinkler.

Today, LEPA has evolved into installations where the sprinklers are placed 30 inches apart ‒ known as close spacing.  By combining the use of Low Drift Nozzle (LDN) Bubbler Pads or LDN Shrouds with conservation tillage, growers are seeing water savings and increased yields. Close spacing installations of LEPA sprinklers offer the following advantages over other irrigation methods:

·         Reduce evaporation loss

·         Avoid wetting crop leaves

·         Prevent wind-drift losses

·         Achieve a more uniform root zone coverage

·         Maximize effectiveness of water usage

LDN bubbler is ideal for maximizing water efficiency.
LDN Shroud is ideal for germination & low crop watering.


LDN Bubbler


LDN Shroud

Success with close spacing can be improved by using the right irrigation equipment and correct farming practices for various field conditions.  Because close spacing sprinklers are mounted 8 to 18 inches above the ground to prevent wind-drift and evaporation, they are best suited for relatively flat farms. Strip-till and no-till farming methods are recommended to avoid run-off.

Circle planting allows the bubble application to be centered in furrows. It is used by growers who want to prevent wetting the crop canopy. The LDN Bubbler Pad gently deposits water directly into the furrows, creating a narrow stream that avoids wetting the foliage. This aerated stream provides a cascade of bubbling water that resists high temperatures and strong winds, allowing 20% more water to reach the soil compared with spray irrigation.

By contrast, the LDN Shroud deflects water down in a wide, dome-shaped pattern that gently delivers the water without spraying. This product is ideal for germination, low crop watering, and sensitive soils that are prone to compaction. Due to its less concentrated distribution pattern, LDN Shroud can be used on fields without furrows and on rolling terrains.

Both options can conveniently be converted back to spray irrigation with just a flip of the deflector pad.

Close Spacing irrigation reduces evaporation rates, ensuring a higher percentage of water usage actually goes to a crop

Water availability and pumping costs are two major issues growers and irrigators have faced in recent years.  Unfortunately, these concerns are far from diminishing, with unpredictable rainfall, increasing temperatures and rising demands for energy and water. Keeping farm profits sustainable and at the same time meeting the growing need for more food, will require the combination of more efficient farming practices and new irrigation application technologies.

Combining the efforts of researchers, manufacturers and growers, Close Spacing irrigation has been gaining ground in many dry regions across the US.  Growers have seen about 25 % in water savings while also enjoying increased yields. They are also adopting this practice in areas where water is beginning to be regulated, or simply as a means to increase yields.

In addition to Texas, where its predecessor LEPA (low-energy precision application) was developed, now close spacing irrigation is effectively used in Arizona, Nevada, New Mexico, California, Kansas, Colorado and Idaho. LEPA was originally used for cotton. Close spacing currently benefits a variety of crops such as potatoes, onions, carrots, alfalfa and corn.

Just like other irrigation solutions, close spacing came about from an ongoing contact with growers and researchers, a strategy that has enabled product development and installation variability to meet specific needs.

Traditional LEPA irrigation helps reduce evaporation losses. In LEPA systems, applicators are mounted far apart to irrigate every other furrow, which translates to a precision application that wets less than half the soil surface. A few years ago, growers in northern Texas looked at combining conservation tillage practices with LEPA heads but closing up the drop hose spacing. Water distribution over most of the soil surface increased the application efficiency; crop residue held the water in place, allowing it to soak in and fill the soil profile.

The versatility of bubble sprinklers, such as the LDN with its bubbler pad and shroud, offers growers the opportunity to combine spray application with bubble application at various crop stages. Bubble sprinklers also alter height off the ground, the spacing of the first spans and the application rate by irrigation cycle.

Close spacing adoption by growers across the country is reliable evidence of the effectiveness of the practice. In addition to growers’ enthusiasm, close spacing and LEPA technology have also attracted the interest of several researchers. Leon New and Guy Fipps of Texas A&M determined that with LEPA sprinklers, at least 20 percent more water will reach the soil surface than with conventional spray nozzles. This technology has been used primarily for row crop irrigation with application efficiencies typically exceeding 95 percent.

As part of the Irrigation Sustainability Component of the Canada-Saskatchewan Agricultural Green Plan Agreement, a study was initiated in 1994 to evaluate the potential of implementing LEPA technology in Saskatchewan. This study indicated differences between the conventional high-pressure and low-pressure center pivot technology. Compared to the high-pressure application, low-pressure application (LEPA) achieved greater application efficiency and a reduction in energy consumption. Per the study, “Crop yield for a high-water-use crop (i.e., fava bean) displayed increased yield using low-pressure system application.”


Close Spacing irrigation using LDN sprinklers in Nevada

Trials conducted by irrigation specialists Howard Neibling and Troy Peters in different parts of Idaho, Washington, Oregon and Nevada generated interest among Northwest growers. Neibling and Peters tested LEPA in wheat, alfalfa, oats, mint, silage corn, grass seed and beans, and observed good soil infiltration. Arco, Idaho, grower Mark Telford stated his intention to use LEPA in potatoes after he witnessed water savings in wheat under windy conditions.

A recent publication described an irrigated cotton field trial that included Senninger nozzles used for LEPA instead of traditional flood irrigation. The trial was developed at the USDA-ARS’s U.S. Arid-Land Agriculture Research Center in Maricopa, Ariz., where once again the declining of water supplies is calling attention to more efficient systems.

Natural Resources Conservation Service officials in Texas have endorsed conversion of existing center pivots and linears to precision application-residue managed (PARM) sprinklers, which qualify for federal funding. PARM is based on LEPA and close spacing principles that promote better irrigation practices that save water and energy and produce better yields.

Mini-Wobblers are suitable for Solid Set, Nursery & Greenhouse Irrigation.

Mini-Wobblers are suitable for Solid Set, Nursery & Greenhouse Irrigation. They provide instantaneous and uniform coverage over a large area. Mini-Wobblers are designed to operate at low pressures and deliver consistently sized droplets resistant to wind-drift and evaporation. As is typical of Senninger Wobbler® technology, these little maximizers help growers save energy and increase benefits through efficient irrigation practices.

The upright mini-Wobbler is often used for container crops or in field irrigation.  It mounts readily to a riser adapter which offers great installation flexibility with the ability for easy relocation from one field to the other.  The inverted model, ideal for tunnels with high walls, allows unobstructed cultivation inside the greenhouse.



Xcel-Wobblers provide instantaneous and uniform coverage over a large area.

Xcel-Wobbler’s larger flows provide a greater area of instantaneous application minimizing the impact of the sprinkler pattern preserving the soil structure and infiltration capabilities.  It also helps prevent run-off.  This energy-saving sprinkler can achieve a Distribution Uniformity in excess of 95%, with very low evaporative loss.  Its counter-balance design reduces vibration for smooth, stable performance.  Xcel-Wobbler is ideal for germination, salt leaching and frost protection.

Senninger Wobbler technology

In 1978 Senninger marked an important milestone by introducing Wobbler® technology, which combined the rotation of a grooved deflector with wobbling action.  This innovative design launched a new generation of sprinklers, providing irrigators with the benefits of lower application intensity, excellent distribution uniformity and large area of coverage at low pressures.

Featuring these benefits, mini-Wobblers and Xcel-Wobblers have become two of the most effective water applicators for the Solid Set systems.

A Closer Look at Close Spacing

No comments

Bubble heads use less energy than conventional sprinklers, and provide a narrow stream that avoids wetting the foliage.

In the mid 80’s researchers at the Texas A&M Research & Extension Center worked with Senninger Irrigation to develop the first Low Energy Precision Application (LEPA) sprinkler.  Using LEPA bubble sprinklers close to the ground helped combat wind-drift and evaporation and helped them make the most out of the water they had.

A few years ago, North Texas growers looked at combining conservation tillage practices with LEPA heads but closing up the spacing. This distributes water over most of the soil surface increasing the application efficiency”. The crop residue holds the water in place allowing it to soak in and fill the soil profile.  Subsequent fewer irrigation cycles are required to keep water in the root zone to promote crop development. For growers, this means irrigation can be reduced from watering over a seven day cycle to watering over a two day cycle.

Growers now use strip-till and no-till switching their regular spray systems to LEPA (Low Energy Precision Application) bubble sprinklers, such as Senninger’s LDN Bubbler Pad and LDN Shroud, and strategically placed the sprinklers closer together and low to the ground.

The Senninger double gooseneck combined with the Truss Rod Hose Sling facilitates precise spacing by creating two drops from one outlet. Growers saw significant water savings and increased yields and in fact, Texas NRCS has endorsed conversion of existing center pivots and linears to a Precision Application – Residue Managed (PARM) sprinklers which qualify for funding.

Weather patterns have created renewed interest in this type of irrigation practice in many areas of the US. In addition to Texas, now close spacing irrigation is effectively used in Arizona, Nevada, New Mexico, California, Kansas, Colorado and Idaho.

Growers are combining various components of this practice differently and achieving great success. They alter the spacing on the first few spans, combine spray application with bubble applications at various crop stages, vary the sprinkler height off the ground, and even alter the application rate by irrigation cycle. Numbers vary by soil type and crop but typically there are yield increases and yet a 20% water savings.

How do LEPA sprinklers irrigate?

Bubble heads use less energy than conventional sprinklers and can operate at lower flows anywhere from 0.27 to 21.18 gpm.

Senninger offers two types of bubble applicators:
The  LDN Bubbler Pad deposits water straight down into furrows and distributes water in a narrow stream that avoids wetting the foliage. This aerated stream provides a cascade of bubbling water instead of a fine mist, so growers don’t have to worry about evaporation due to high temperatures and low humidity or strong winds blowing away fine droplets.

The LDN Shroud deflects water down in a wide dome-shaped pattern that gently distributes water without spraying. This type of bubble can be used on fields without furrows and on rolling terrains due to its less concentrated distribution pattern. The LDN Shroud is ideal for germination and low crop watering and for growers concerned about compaction of sensitive soils.
