Phosphorus has always been essential for attaining high-yielding crops. But today, it’s also one of growers’ biggest financial challenges. Since May 2025, phosphorus fertilizer prices have increased by 16%, while DAP prices climbed another 6% from April to May 2026, reaching an average of about $914 per ton. Grain prices have also remained under pressure, forcing growers to rethink one of their largest input investments.
However, many are asking a different question: How can I get more output from the phosphorus I already have?
Instead of applying more phosphorus to maximize yield potential, growers can improve the return on every fertilizer dollar by making better use of the nutrients already present in their soil.
Understanding Phosphorus Use Efficiency
Unlike nitrogen, phosphorus doesn’t readily leave the field. Instead, much of it becomes chemically tied up in the soil shortly after application. As phosphorus reacts with positively charged elements such as calcium, magnesium, iron and aluminum, less of the nutrient remains available for crop uptake.
This has challenged growers for decades. Many fields contain substantial phosphorus reserves, yet crops can still struggle to access enough of the nutrient during key growth stages. With fertilizer prices placing additional pressure on profitability, maximizing phosphorus availability has become just as important as the application itself.
“The goal isn’t simply applying more phosphorus—it’s getting more value from every pound,” said Dave Schwartz, Vice President, Strategic Retail Accounts at Verdesian Life Sciences.
A New Approach to Phosphorus Management
Historically, phosphorus-efficiency technologies have focused on preventing newly applied nutrients from becoming fixed in the soil. Verdesian’s Phree-uP® technology builds on that foundation with a dual-action approach designed to help growers improve phosphorus availability in two ways.
First, Phree-uP® helpshelps protect newly applied phosphorus, keeping more of the fertilizer investment available for crop uptake. Second, the technology is designed to stimulate phosphorus-solubilizing enzymes and beneficial microbial activity that release phosphorus tied up in the soil, making previously unavailable nutrients more accessible to growing plants.
These two mechanisms help address both current fertilizer applications and the long-term phosphorus reserves many fields have accumulated through years of commercial fertilizer or manure applications. Across 66 sites from 2021 to 2025 in trials of cherry, corn, cotton, peanut and potatoes, Phree-uP®’s dual-action approach increased yield by 8.8%.
Tapping Into Your Phosphorus “Bank Account”
“Many fields already have a full bank account of phosphorus. The challenge is making more of it available to the crop,” noted Schwartz.
Across much of the Midwest and other production regions, fields have accumulated significant phosphorus reserves over decades of fertilizer and livestock manure applications. While soil tests often indicate elevated phosphorus levels, much of the nutrient remains chemically unavailable to crops.
By helping make some of those existing phosphorus reserves available, growers have an opportunity to improve nutrient use efficiency while potentially reducing reliance on high-cost fertilizer applications.
Confidence and Flexibility Amid High Fertilizer Prices
As phosphorus and other agricultural input costs continue to rise, many growers are evaluating ways to reduce application rates. The challenge, however, is doing so without sacrificing yield.
Field experience with Phree-uP® has shown encouraging results in maintaining crop performance at lower phosphorus application rates. In some comparisons, reducing phosphorus inputs from 100 to 75 pounds per acre with Phree-uP® yielded results comparable to applying the full rate without the technology.
That kind of flexibility can have a meaningful economic impact during years when fertilizer costs are elevated.
Improving ROI and Long-Term Sustainability
Every fertility decision ultimately comes down to return on investment and growers’ long-term sustainability. With fertilizer costs expected to remain elevated in 2027, today’s market conditions are forcing both growers and retailers to find ways to stretch fertilizer dollars without compromising productivity.
For growers facing higher fertilizer costs and tighter margins, improving phosphorus availability isn’t just about nutrient management; it’s about protecting profitability. And for retailers, helping customers maximize nutrient efficiency creates an opportunity to deliver greater value while supporting agronomic success.
Verdesian Life Sciences offers a comprehensive portfolio of nutrient use efficiency products that support growers’ ROI and long-term sustainability, including Phree-uP®, which was recently registered for distribution in the Canadian and California markets.
