Nabta-URP 17-44-0 (Urea Phosphate)
Highly acidic crystalline fertilizer (pH ~2.0 in solution). Dual purpose: nutrient supply + soil/water pH correction for alkaline and calcareous soils.
Application Guidelines
- Fertigation: Use in all fertigation schedules when potassium is not required. Excellent for cleaning calcium carbonate deposits from drip lines
- Foliar: Low concentration (< 1%) for phosphorus supplementation
- Soil application: Acidifies root zone in high-pH soils, improving micronutrient availability
- Key benefit: In alkaline soils (pH > 7.5), URP unlocks fixed phosphorus and improves Fe, Zn, Mn uptake
- Caution: Do not mix with calcium or magnesium products. Start with lower rates in sandy soils
