Growers are always looking for ways to maximize yields. This can mean installing irrigation equipment in areas where the water supply is less than ideal.
Troy Long, Valley® director of product management, says that growers are continuously looking for more land to be placed under irrigation.
“In some instances, this means that the water supply available may be less than desirable from a water quality standpoint.”
Corrosive water shortens the life of irrigation machines, Long explains. “Often, dealers are submitting water samples on behalf of the grower to determine the expected life of the machine pipeline before the grower makes that investment.”
Essential Durability and Reliability
Shan Carling of Carling Farms grows corn and alfalfa near Orem, Utah. He started replacing his galvanized center pivots with PolySpan® machines about eight years ago when he began losing his battle with corrosive water.
“Our water just eats up galvanized pipe around here. I’ve seen machines fall down after six years because the water corrodes the pipe so quickly,” says Carling. “We’d usually have to replace our pivots after about 15 years, so we decided PolySpan was worth the investment. Our PolySpan pipes should last forever,” he explains. “From all I’ve seen, they’ll probably be around longer than I will.”
Today, Carling has 14 PolySpan machines and only three galvanized pivots. “When the time comes, we’ll replace those three with PolySpan, as well,” he says.
Across the country in South Carolina, Pat Rogers and his family have been growing mostly cotton and peanuts. They’re new to irrigation and appreciative of its benefits.
“Cotton and peanuts are very management and labor intensive,” Rogers says. “We are switching to more corn and soybeans under pivots, because it takes less labor and it’s more profitable. Irrigation also allows for better crop rotation for us.”
Rogers has a stationary pivot and two towable machines that cover five pivot points. All of the pivots are equipped with PolySpan pipe.
Their land sits on a former mineral spring, and the water smells and tastes of sulfur and iron. Based on his knowledge of groundwater conditions and a family member’s recommendation, Rogers opted for PolySpan on all of his irrigation machines.
“We want the longevity and durability,” he says. “We knew right away we were going to invest in the PolySpan solution.”
PolySpan also works well for fertigation, making the investment even more attractive to Rogers.
“We believe the longer lifespan is worth the added cost. We’ll definitely get a greater payback with PolySpan,” Rogers predicts.
To protect their investment, more growers are using Valley PolySpan pipe on their center pivots. PolySpan pipe resists corrosion from water with high or low pH, chlorine, sulfates, saltiness, softness, and more. Protection is provided by coating the inside of a galvanized pipe with High Density Polyethylene (HDPE), a substance that is completely inert and can last indefinitely, no matter what type of water is running through it.
