RhizoSorb Helps Growers Cut Phosphate Fertilizer Costs Without Sacrificing Yield, Phospholutions Says at Commodity Classic

Reducing fertilizer costs without sacrificing yield potential is top of mind for many farmers in today’s uncertain ag economy.

At the Commodity Classic trade show, Brownfield spoke with Craig Dick, Vice President of Sales and Marketing for Phospholutions, who was joined by central Iowa farmer Andy DeVries to discuss how growers are using the company’s RhizoSorb technology to improve phosphorus efficiency.

Dick says RhizoSorb allows farmers to reduce the cost of phosphate fertilizer without taking the risk of skipping an application to save money.

Although growers might think about cutting back on phosphate when margins are tight, Dick says that can come with a downside yield risk. With RhizoSorb, he explained, you can maintain your fertilizer program and typically save about 10 percent on phosphate costs while still protecting yield potential.

DeVries says he has been using Phospholutions products on his farm for four years after first trying RhizoSorb on a trial basis. Since then, he says the results have been consistent—even through challenging weather conditions.

DeVries says the current agricultural landscape can feel uncertain, but he appreciates the science behind the technology.

“In agriculture right now, absolutes are hard to come by,” he said. “But Phospholutions knows what they’re talking about and they can back it up.”

Dick says the company has just completed its second year of commercial sales with more than one million acres treated with RhizoSorb. Adoption has been strongest across the Midwestern Corn Belt in soybean production, but the company is expanding into new areas.

“We’re also seeing growth in Canada, the wheat belt of Kansas and Oklahoma, and the Pacific Northwest,” Dick said.
