Growers are switching to RhizoSorb to improve their phosphate fertilizer and seeing real results -- from lower per acre cost to higher yield. Explore below to see RhizoSorb in action, hear from other growers, and see our latest trial data.
With twice the phosphorus efficiency, apply 50% less phosphorus for equivalent agronomic output. That translates to a 10% savings per acre, compared to MAP.
RhizoSorb has been tested on major row crops, including corn, soy, wheat, canola, and potatoes. With five years of data, RhizoSorb consistently delivers the same or better yield.

From the field, growers often ask:
Rhizosorb 8-39-0 is a next-generation dry phosphate fertilizer that replaces MAP or DAP.
RhizoSorb technology is incorporated into traditional phosphate manufacturing, resulting in a finished granule that improves phosphate use efficiency, reduces input costs, and maintains crop yields.
Phosphate is adsorbed onto the surface of RhizoSorb® during granulation and keeps phosphorus from tying up in the soil when applied to fields.
RhizoSorb® controls the release of phosphorus based on plant needs rather than environmental conditions like MAP or DAP.
RhizoSorb® reduces soil tie-up and environmental loss by keeping more of what's applied available throughout the season.
In addition to years of product development and research by Penn State, hundreds of replicated, small plot and on-farm trials have been completed. Trials have been conducted across 18 states and over a period of 5 years.
RhizoSorb® reduces phosphate runoff by 78%. In addition, a third-party Life Cycle Assessment shows RhizoSorb® has a 45% lower GHG footprint per acre than traditional MAP.
RhizoSorb® can be blended and applied like any other dry fertilizer and the application method doesn’t affect performance.
RhizoSorb® is available now! To learn more about RhizoSorb®, contact Phospholutions to connect with a regional sales representative or reach out to your local ag retailer.
Although the cost per ton is higher, RhizoSorb® is cheaper per acre than MAP. RhizoSorb® is more efficient; therefore, we use less fertilizer to deliver the same amount of phosphate to the crop.
On average, growers save $5-7 per acre, and RhizoSorb® has demonstrated a yield increase of 3-5 bushels, generating an ROI of $20 per acre compared to MAP.
Unlike other products on the market, RhizoSorb® has reliable and consistent results across crops and soil types. It doesn't cost more to use, and no changes to retail or farm operations are needed. RhizoSorb® technology is not a biological or biostimulant but rather a soil chemistry approach to controlling the release of applied phosphates.
Growers can take advantage of RhizoSorb®'s Grower Guarantee Program. This program protects their revenue up to $40 per acre if yields are less than their 10-year APH or actual production history. Growers must apply a minimum of 200 acres of RhizoSorb® to corn or soybeans and enroll at Phospholutions.com.
RhizoSorb® 8-39-0 helps growers improve phosphorus efficiency while also reducing fertilizer application rates — creating operational advantages beyond nutrient performance. The article explores how lower fertilizer rates can reduce refill stops, improve planting efficiency, streamline logistics, and help growers maximize narrow planting windows. By extending acres covered per fill and reducing downtime, RhizoSorb can improve overall system efficiency and help protect yield potential through more timely planting.
Phosphorus has long been managed under a “build and maintain” philosophy: apply enough fertilizer to keep soil phosphorus levels high and protect yield potential. But this article explores the hidden downside of that approach. As soil phosphorus levels rise, crops can begin taking up more phosphorus than they actually need — a phenomenon known as luxury consumption. That extra uptake doesn’t increase yield, but it does increase nutrient removal, fertilizer replacement needs, and overall production costs.
As fertilizer affordability and domestic supply concerns continue to intensify, Phospholutions urged policymakers to consider phosphorus efficiency as a practical and immediate lever to strengthen U.S. fertilizer resilience.
Phospholutions today announces a year of commercial growth as the company enters its next phase of adoption. The milestones come as phosphorus has been designated a U.S. critical mineral, with supply increasingly constrained and price volatility rising, highlighting the significant need for greater nutrient efficiency.
Phospholutions announced today the addition of Julia Andrus as Marketing & Communications Manager, strengthening the company’s commercial capabilities as adoption of its phosphorus efficiency technology continues to grow.
