Product description
Urea phosphate (UP 17-44-0) is a fully water-soluble, acidic combination of urea and phosphoric acid, supplying nitrogen and phosphorus while lowering the pH of irrigation water and the root-zone micro-environment, which helps release phosphorus that would otherwise be fixed in calcareous or alkaline soils.
Dual nutrition and pH correction
Delivers readily available nitrogen and phosphorus together with an acidifying effect that improves nutrient availability in high-pH soils and irrigation water.
Clean dissolution for fertigation
Fully water-soluble with no insoluble residue, making it compatible with drip and sprinkler fertigation systems without clogging emitters.
Soil & drip-line maintenance
Periodic use helps prevent calcium carbonate scaling in drip lines and emitters irrigated with hard or alkaline water.
Specification
Available in fertigation and foliar grades.
| Product | Specification | Total-N% | P2O5% | K2O% | Solubility |
|---|---|---|---|---|---|
| UP | 17-44-0 Fertigation Grade | 17 | 44 | – | 100% water-soluble |
| UP | 17-44-0 Foliar Grade | 17 | 44 | – | 100% water-soluble |
Key usage scenarios
Where urea phosphate delivers the most value.
Drip & sprinkler fertigation
Clean, residue-free dissolution keeps emitters and filters clear while delivering N and P directly to the root zone.
Calcareous & high-pH soils
The acidifying effect helps convert fixed soil phosphorus into plant-available forms.
Hard or alkaline irrigation water
Periodic dosing helps prevent carbonate scale build-up in drip lines and emitters.
Foliar nutrient correction
Fast-acting foliar source of nitrogen and phosphorus during critical growth stages.
Advantages
A precise, acid-forming NP source for modern irrigation systems.
Full water solubility
No insoluble residue, ideal for fertigation and foliar application equipment.
Soil-pH correction
Acidifying action helps unlock phosphorus fixed by calcium or high pH.
Irrigation-system maintenance
Helps control carbonate scaling in drip and sprinkler infrastructure.
Fast nutrient availability
Readily available nitrogen and phosphorus for rapid crop response.
Application flexibility
Suited to fertigation, foliar spray and combined soil-and-irrigation-water treatment.
