Day 1: Compound Fertilizer Production Hall & Warehouse

Delayed Evening Tour Due to Safety Inspection

Arrival & Schedule Adjustment
The Korean delegation arrived in Tai’an at around 16:00. At the time, senior management was conducting a safety inspection of the factory. To ensure safety and production order, the factory arranged the tour after the inspection was completed.
Tour Highlights
- Raw Material Weighing & Automated Blending: Demonstrated automated formula systems ensuring precise NPK ratios.
- Mixing & Granulation: Explained key parameters of wet/dry mixing and drum granulation processes.
- Drying, Screening & Packaging Logistics: Showcased intelligent packaging, automated palletizing, moisture protection, and FIFO warehouse management.

The delegation highly appreciated Risso’s strict adherence to production safety, quality management, and warehouse traceability systems.

Day 2: Resin Coated Urea Production Line

The second-day focus was on Risso’s newly built Polymer Coated Urea (PCU) production line. The technical team provided detailed demonstrations of:

Automated Production Equipment
Including pre-heating granulation, resin coating, drying & curing, and online quality inspection systems, highlighting efficient and stable production.
Online Quality Control
Real-time monitoring of coating thickness, nitrogen content, and release curves ensures consistent controlled-release performance.

Laboratory Float Test

To verify PCU’s performance in shallow water applications such as paddy fields, the delegation observed laboratory float tests:

Testing Method: Small samples were taken from bulk product and placed in lab water tanks to observe sedimentation speed and depth.
Results: The resin-coated urea pellets were uniform and sufficiently dense, fully sinking within minutes, demonstrating excellent anti-floating performance suitable for Korean paddy cultivation.

The three-member delegation expressed high appreciation for both the test results and the production line automation, and showed strong interest in further field trials and long-term supply cooperation.

Polymer Coated Urea (PCU)) Technology Highlights

Precision Release: Multi-layer resin coatings enable customizable release cycles ranging from 30 to 120 days, adaptable to various crops.
Durable Coating: Resistant to mechanical damage, suitable for long-distance transport and diverse fertilizer application equipment.
Environmental Benefits: Reduces nitrogen volatilization and leaching, improves fertilizer efficiency, and complies with Korean and international environmental standards.

Business Discussions & Cooperation Prospects

Risso and the Korean delegation discussed market requirements, customized formulations, and long-term supply. The delegation highlighted Risso PCU’s anti-floating, long-release, and automated production capabilities and confirmed plans to proceed with field trials and procurement cooperation.

Conclusion: Risso’s Ongoing Innovation

This visit not only confirmed the safety, reliability, and high quality of Risso’s compound fertilizer and PCU products, but also demonstrated the company’s leading position in controlled-release fertilizer technology, intelligent production, and quality management systems. Risso will continue to innovate, providing high-efficiency and environmentally friendly fertilizer solutions for global agriculture.
