Urea Phosphate (UP)

Key Specifications

Final acceptance limits and analytical methods should follow the agreed specification and batch Certificate of Analysis (COA).

Applications

1. Fertigation

• Nitrogen and Phosphorus Supply: Provides both nutrients through suitable irrigation systems.

• Acidifying Action: Helps lower irrigation-water pH, depending on water alkalinity and application rate.

• Program Selection: Match the nutrient contribution to crop needs and the existing fertilizer program.

2. Soluble Fertilizer Production

• Fertilizer Blends: Used as a nitrogen-phosphorus component in suitable soluble formulations.

• Liquid Fertilizers: Used in selected liquid fertilizer preparations.

• Compatibility Checks: Confirm dissolution, final pH and compatibility with other ingredients.

3. Irrigation-Water Management

• Bicarbonate Reduction: Its acidity can help neutralize bicarbonates in irrigation water.

• Deposit Management: May help limit carbonate-related deposits under suitable operating conditions.

• System Evaluation: Check water chemistry, equipment compatibility and final nutrient levels before use.

Safety and Handling

Urea phosphate is acidic and corrosive and can cause severe skin burns and eye damage. Avoid inhaling dust and prevent skin and eye contact.

Use suitable protective gloves, protective clothing and eye/face protection. Follow the current Safety Data Sheet (SDS) for handling, storage and spill procedures.

Frequently Asked Questions

Does urea phosphate supply potassium?

No. A 17-44-0 grade provides nitrogen and phosphate but no declared potassium. Potassium should be supplied separately where required by the crop nutrient program.

Can it be mixed with calcium nitrate?

Do not combine it with calcium-containing fertilizers in the same concentrated stock solution, as precipitation may occur. Use separate stock tanks and confirm compatibility for the intended system.

How much is needed to reduce irrigation-water pH?

The required amount depends on water alkalinity, target pH and the nutrient contribution. Water pH alone is insufficient to determine the application rate.

Can it remove every type of irrigation blockage?

No. Acidification may help manage carbonate-related deposits, but blockages can also arise from suspended solids, biological growth or other precipitates. Identify the cause before selecting a treatment.
