DuraPHOS
Triple Super Phosphate Fertilizer
Spring Phos. Minimize seedling loss.
DuraPHOS™ is a nitrogen-free, straight phosphate fertilizer platform ideal for spring application, serving as the foundation for a proactive soil nutrition strategy. As a water-soluble phosphate, DuraPHOS has demonstrated equivalent agronomic performance to ammoniated phosphate fertilizers. With its low salinity, DuraPHOS reduces potential seedling loss, enables precision application and maintains soil productivity.



An Effective Fertilizer for Spring Application that Maximizes Seed Safety
DuraPHOS offers a safer solution for phosphate needs as part of your spring planting plan. Relative to ammoniated phosphates like MAP and DAP, DuraPHOS has lower salinity and is ammonium free, making it a safer option to avoid seedling injury due to salt stress and ammonia toxicity.
Fertilizer Flexibility Through the 4Rs
DuraPHOS is the straight phosphate fertilizer that offers flexibility for variable rate application. With our DuraPHOS platform, you can optimize soil productivity by applying the exact amount of phosphate you need, precisely where your crops need it, whether seed-placed, banded or broadcast. This flexibility allows you to differentiate nutrient application according to changing needs throughout the plant cycle without compromising seed safety. As a single-source fertilizer, DuraPHOS enables precision phosphate placement.
DuraPHOS provides farmers with the 4Rs:
- The right nutrient
- In the right amount
- At the right time
- In the right place


Ultimate Phosphate Availability
While DuraPHOS draws on the strength of phosphate rock, it is a complex product made from phosphoric acid (H3PO4) and treated rock phosphate. Together they enhance phosphate availability and usability for farmers.
