Grower Testimonials
RhizoSorb, backed by testimonials from farmers in the field.
We have been using RhizoSorb on our farm for three years to save time on application, enhance phosphorus uptake, and achieve the same or better results with less fertilizer.
We've used RhizoSorb on over 1,000 acres to enhance phosphorus availability and uptake, helping us get the most value from our fertilizer investment.
RhizoSorb makes phosphorus more readily available and you can see it in the tissue phosphorus levels with more visual root mass. It's an easy switch from MAP.
Trying RhizoSorb in strip-till applications has been stable and we have not had any issues with compatibility. We have seen better phosphorus levels and yield.
Better Efficiency. Improved ROI. Proven Technology
RhizoSorb 8-39-0 is the Next Generation of Phosphorus Fertilizer that is proven in hundreds of small plot and on-farm trials demonstrating consistent yield results and cost savings to row crop producers across North America.
Insights from Phospholutions
Understanding P Build-Up at the Surface and Depletion Below
Why do some crops struggle to access phosphorus even when soil-test levels appear adequate? Technical Agronomist Taylor Strehl shares how phosphorus stratification develops in modern reduced-tillage and no-till systems, creating uneven nutrient distribution throughout the soil profile. Learn why phosphorus placement, fixation, and accessibility impact crop nutrition, how standard soil tests can miss subsurface depletion, and how RhizoSorb® technology helps improve phosphorus availability by expanding the zone of plant-accessible phosphorus.
The RhizoSorb Efficiency Cascade
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.
The Catch-22 of Phosphate Soil Fertility
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.
Phospholutions Calls for Fertilizer Efficiency to Be Included in U.S. Supply and Affordability Strategy
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 Marks Year of Growth; Adoption Accelerates Ahead of Spring Farming Season
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.
