Liquid Ammonium Polyphosphate Details
Risso® Liquid Ammonium Polyphosphate (APP) is a high-purity, water-clear phosphorus fertilizer designed for efficient early-stage crop nutrition. With a balanced formulation of 10–11% nitrogen and 34–37% phosphate (P₂O₅), Risso® APP delivers rapid phosphorus uptake and extended availability, making it the ideal choice for starter fertilizer programs across row crops, vegetables, and specialty crops.
Formulated through advanced ammoniation of phosphoric acid, it combines orthophosphate (readily available) and polyphosphate (gradually released), promoting both immediate root activation and long-term phosphorus support.

Key Benefits
Dual-Form Phosphorus Delivery
~30–40% orthophosphate for fast absorption + ~60–70% polyphosphate for sustained release100% Water-Soluble, Crystal-Free
Clear liquid solution that prevents plugging in fertigation and banded systemsEnhanced Nutrient Mobility
Polyphosphate chains can chelate micronutrients like zinc, iron, and manganese, improving bioavailabilityFlexible Application Compatibility
Suitable for drip irrigation, starter banding, foliar feeding, and tank mixingCrop Safety & Soil Compatibility
Neutral pH (~6.0–6.2) ensures safe placement near seeds or roots without phytotoxicityOptimized for Precision Agriculture
High analysis, consistent formulation supports GPS-guided placement and liquid nutrition systems
Recommended Use Guidelines
| Application Type | Rate (Typical) | Best Timing |
|---|---|---|
| Starter Band (in-row) | 2–4 gal/acre (20–40 L/ha) | At planting or transplanting |
| Drip Fertigation | 3–7 L/ha/application | Early vegetative and root stages |
| Foliar Spray | 1% solution (v/v) | During P-demanding growth phases |
| Tank Mixing | Compatible with most NPK and micros; avoid mixing with alkaline inputs or calcium-based products |
💡 Pro Tip: Apply Risso® APP in cool, moist soils where phosphorus availability is limited. Early application ensures improved root architecture and stand uniformity.
