Comparison between Rongqing’S KIESERITE and ESTA® Kieserit GRAN
Those who frequently gain exposure to magnesium fertilisers, Kieserite, and magnesium sulphate, will undoubtedly be familiar with K+S’s ESTA® Kieserit GRAN. Both are kieserite products, but what distinguishes Rongqing Chemical’s kieserite granular from K+S’s ESTA® Kieserit GRANular? Let us briefly introduce the manufacturers of these two product categories:Rongqing Chemical, one of China’s established sulphate producers, operates its magnesium sulphate and sulphate-magnesium fertiliser facilities in Yingkou, Liaoning, where known as China’s Magnesium Capital. Leveraging Yingkou’s magnesite resources, Rongqing runs five modern production lines with sulphation technology, achieving a daily output of 500 tonnes for Kieserite granules and an annual capacity of 20,000 tonnes for magnesium sulphate. Rongqing Chemical is certified with ISO9001, FAMI-AS, and REACH registrations, consistently supplying various trace element magnesium fertiliser raw materials to global branded fertiliser manufacturers, distributors, importers, high-end fertiliser R&D entities, and raw material procurement operations.K+S, is a global salt producer and a leading potash fertiliser supplier. It maintains production bases in Europe and the Americas, with distribution centres in Africa and Asia. K+S pursues the policy of regional procurement and supplying mineral raw materials, products, and solutions to customers worldwide. To summarise comprehensively, the similarities and differences between Rongqing Chemical’s Kieserite Granular and K+S’s ESTA® Kieserite Granular are as follows: Similarities: 1. Both are mineral fertilisers, with magnesium and sulphur as their primary fertilising elements.2. Post-application benefits for crops include: immediate supply of dual sulphur-magnesium elements, suitability for diverse soils with pH restoration properties, synergistic enhancement of NPK fertiliser utilisation, promotion of root growth, and improved crop absorption capacity.3. Physical characteristics and application advantages: suitable for standalone application or blending with NPK fertilisers without reaction, making it an ideal co-blended fertiliser choice for farm fertilisation systems. The granular fertiliser exhibits excellent hardness and uniform particle size, making it suitable for modern mechanised fertilisation operations.4. Suitable…
