Subsurface Drip Irrigation Demo at Husker Harvest Days

During Husker Harvest Days (HHD) this year, you’ll have a hard time seeing the newest irrigation addition at the show site six miles west of Grand Island. That’s because it’s underground.

A subsurface drip irrigation (SDI) system is watering a corn field south of the exhibit area in 2013. It’s the first time an SDI system has been installed at HHD. For 35 years, HHD has showcased irrigation technology and has featured center pivot manufacturers, pipe manufactures and dozens of other irrigation equipment suppliers. About every type of center pivot and lateral-move system has been installed during those years.

Roger Luebbe, site manager at HHD, says the SDI system replaces a hose-drag lateral move sprinkler that had been there for years and was “showing some fatigue.” Because of its efficiency and water delivery uniformity, SDI can save one-third of the water applied by a center pivot and 2/3 of the water applied by gravity irrigation systems.

Drip Irrigation Product Catalog – now available in English and Spanish Languages

Toro Micro-Irrigation Product CatalogToro recently announced that its micro-irrigation (aka. drip irrigation) product catalog for the agriculture industry is now available in both English and Spanish languages. The catalog covers Toro’s entire micro-irrigation product offering and highlights features, benefits, and specifications for each product.

However, what’s most interesting is that with the addition of a Spanish language catalog, Toro has displayed its dedication to customers throughout Latin America, as well as its commitment to accuracy and quality.

Texas Farm Increases Efficiency with Subsurface Drip Irrigation (SDI)

Crops Manager for Daisy Farms, Jeff Fowler, is utilizing subsurface drip irrigation (SDI) and GPS technology to improve the dairy and crop operation’s efficiency. The subsurface drip irrigation system was installed on clay soils to make good on its commitment to conservation and environmental stewardship, as well as to get the most out of every drop of water.

“Drip irrigation is close to 100 percent efficient,” Fowler says. “We put water straight to the roots; we get no runoff; we don’t need as much water. When we put on a half-inch, we get a half-inch. We don’t have to apply three-fourths of an inch to get what we need.”

Toro Irrigation During a Drought: Subsurface Drip Irrigation (SDI)

As the worst drought in 50 years gripped America’s farmland in the summer of 2012, and crop failure was rampant, three Nebraska producers reported increased soybean yields and significantly lower water use at the same time by using Subsurface Drip Irrigation (SDI) to deliver water and nutrients directly to the roots of their crops. This was in contrast to the typical practice of applying water to the surface with gravity or sprinkler irrigation systems. In addition to improved yields and resource use efficiency (RUE), other benefits cited included an improved ability to farm in drought conditions, improved flexibility and improved convenience. In each of these case studies, the producer found SDI a worthwhile investment.

Farmers Increase Production, Efficiency with No-Till & Drip Irrigation

SDI on CottonCalifornia cotton growers and water-starved fields could benefit from a conservation tillage practice not typical to this Golden State cash crop, although the practice is widely implemented and accepted elsewhere in the United States.

At Lucero Farms in Firebaugh, Calif., the decision this spring to implement no-till practices on cotton planted in western Fresno County seems a good one given a 20-percent water allocation via the State Water Project.

Colorado Farmers Try Subsurface Drip Irrigation

In the back of almost every farm truck you are likely to find a pair of muddy irrigating boots. Stepping in the mud to shovel and straighten creases is common in the area, so getting muddy boots is just part of the job for most farmers. But one type of irrigation has the potential to get rid of some of the muck.

Subsurface drip (SDI) is a low-pressure, high-efficiency irrigation system that uses buried drip tubes or drip tape, essentially plastic tubing with holes in it, to meet crop water needs. This type of irrigation effectively waters the crops but keeps the surface dry. “The thing about this is that there is no run-off. If we do it correctly, there is no deep percolation. So essentially everything goes to the crop. So it’s very, very efficient,” said Calvin Pearson, research agronomist at the Colorado State University Fruita Agricultural Experiment Station.

Grants & Drip Irrigation Seen as Solution to Nitrate Contamination

Nitrate contamination is a common issue for growers in the Salinas Valley. Since nitrates can cause serious health issues and can negatively affect marine wildlife, significant grant money is being devoted to the issue. Drip irrigation is also part of the solution since it applies the right amount of water exactly where it is needed, increasing plant health and minimizing runoff.
