MustGrow and Phospholutions sign distribution agreement

MustGrow and Phospholutions sign distribution agreement

RhizoSorb® can increase phosphorus efficiency by up to 50% when substituted for conventional commodity fertilizers and applied to corn and other crops.

Phospholutions entered into a distribution agreement with MustGrow in June. This allows MustGrow to sell RhizoSorb through NexusBioAg, its Canadian sales and distribution division.

RhizoSorb® is a patented technology designed to substitute for conventional commodity fertilizers such as monoammonium phosphate (MAP) and diammonium phosphate (DAP). The technology, because it can be integrated into the phosphate production process, offers the same ease of application as these traditional granular fertilizers, while requiring no changes to existing equipment or practices.

RhizoSorb® increases phosphorus efficiency by up to 50%, according to Phospholutions, allowing farmers to half the amount of phosphorus traditionally applied, while maintaining (and even improving) yield. By optimising fertilizer inputs and reducing costs without sacrificing yield, the resulting improvement in nutrient use efficiency translates to a better return on investment for growers – equating to potential savings of up to $20 per acre.

In addition to its economic benefits, RhizoSorb® delivers a host of environmental advantages, according to Phospholutions, such as reducing CO2 e emissions by 45%, phosphorus runoff by 78% and leaching by 84%, compared to conventional MAP fertilizer.

“With approximately 94.5 million acres of crop production that depend on phosphate, Canada is a key market,” said Craig Dick, sales and marketing VP at Phospholutions. “We are proud to partner with MustGrow to deliver RhizoSorb® to retailers and growers across Canada.”

“This partnership marks another major milestone in Phospholutions’ journey,” added Hunter Swisher, CEO of Phospholutions. “Partnering to bring more cost-effective fertilizer solutions to the Canadian market supports our broader global expansion efforts.”

“MustGrow and Phospholutions share a common mission to improve the global food system through sustainable production solutions,” said Colin Bletsky, COO of MustGrow. “Phosphorus is the second most-used nutrient in global food production, making its efficient and responsible use a top priority for both our companies and the growers we serve.”

Phospholutions also signed a US distribution agreement with The Andersons in May. This allows The Andersons to distribute RhizoSorb® from the 2026 crop year onwards.

“We are thrilled to expand our partnership with The Andersons through this distribution agreement,” said Hunter Swisher. “Their trusted presence in the Midwest and long-standing commitment to innovation in agriculture make them an ideal partner as we scale RhizoSorb across the U.S.”

Alongside this distribution agreement, Maumee Ventures, The Andersons venture capital arm, recently led an additional round of investment in Phospholutions, underlining their confidence in the company, its technology and long-term vision.

“As an early investor and partner, we continue to be impressed by the progress the company has made in scaling their solution to improve phosphorous efficiency, and we are looking forward to this next chapter in our relationship with the company,” said Andy Spahr, SVP for Agribusiness at The Andersons. “As a result, growers throughout the U.S. will soon benefit from greater access to sustainable and high-efficiency phosphorus solutions for staple crops like corn and soybeans.”

Tim Mahoney was recently appointed VP of business development at Phospholutions. He will play a key role in expanding partnerships and supporting international expansion, manufacturing and distribution of RhizoSorb® .

“This agreement with The Andersons is a pivotal moment for Phospholutions and for retailers seeking relief from a supply constrained market,” said Mahoney.

“We’re committed to ensuring RhizoSorb® is readily available and well-supplied to our channel partners.”

Topsoe technology selected for Indiana refinery

Topsoe has been selected as the renewable diesel technology partner for CountryMark’s Mount Vernon, Indiana refinery. Located in southwestern Indiana, the refinery processes 35,000 bbl/d of crude oil. With the addition of Topsoe’s HydroFlex technology, CountryMark aims to produce up to 250,000 barrels of renewable diesel annually. The new unit is expected to enable an emission avoidance of approximately 84,500 t/a of CO2 e. CountryMark, a farmer-owned cooperative, will use local soybean oil as the primary feedstock to produce renewable diesel, helping create a locally sourced renewable fuel economy in Indiana.

Marimaca to acquire acid plant

Marimaca Copper Corp. says that it has recently executed a binding asset purchase option agreement to acquire a used sulphuric acid plant in Chile from CEMIN Holding Minero. Sulphuric acid is one of the key input costs for the Marimaca Oxide Deposit, and the ability to produce a significant amount of its own supply will reduce exposure to a volatile acid market. The agreement has an exclusivity period of three months to allow further detailed technical and engineering reviews including capital and operating cost estimates for the installation and operation of the 150,000 t/a sulphuric acid plant, whose output would represent approximately 30-40% of total acid consumption at the Marimaca Oxide Deposit, depending on the phase of development. Marimaca says that, based on market research and quotations received, the estimated equipment cost of a new sulphuric acid plant of similar capacity is approximately $35-40 million, with a total installation cost of $50-60 million. The cost of breaking down and relocating the plant to the site at Mejillones and the start-up costs of the used plant are expected to be materially lower than cost of new equipment. Indicative operating costs show the potential for an approximately 30% reduction in acid cost relative to current long-term forecast and normal historical spot and contract acid prices delivered to Mejillones.

Upcycle launches potassium sulphate project

Upcycle Minerals Inc. has launched a brine to potassium sulphate fertilizer with carbon capture project in south-central Saskatchewan. The company says that it plans to use its mineral assets, including the Tuxford potash mineral permit and the Whiteshore and Lydden Lake Alkali Leases as feedstock for its patented process. Along with the production of potassium sulphate (SoP), the process also generates two co-products with established markets; ammonium sulphate fertilizer and precipitated calcium carbonate. Upcycle says that it intends to become an ecologically conscious, low-cost producer of SoP with low net CO2 emissions.
