Ny NPK gjødsel for tropiske markeder

Offentlig prosjektsammendrag

Ensuring high-quality NPK products is essential for Yara to maintain its premium position and grow our market share in the field grade NPK segment. Shipment of large volumes of NPK fertilizers to tropical markets presents challenges, as NPK fertilizers are prone to water ab-sorption. This leads to caking, reduced crushing strength and increased dust formation, complicating the handling process in these regions. Preventing water absorption is crucial and a universal solution remains elusive due to the complexity of NPK products. To create an NPK product that withstands tropical conditions, improvements are needed in two areas: 1) Developing advanced coatings that prevent humidity absorption while maintaining anti-caking and anti-dusting properties, and 2) Enhancing the NPK salt matrix with specific additives to improve water-binding properties and physical strength. This project looks at a combination of these strategies, which is expected to offer the best solution.
