September 2021
The September issue of World Fertilizer begins with a report from CRU on Asia’s fertilizer market. In our cover story, Kreber demonstrates how particle engineering can be used to improve nitrogen use efficiency, while Johnson Matthey explores the technologies that have been jointly developed with KBR to enable ammonia and methanol co-production. The issue also focuses on plant safety, with contributions from Reuter-Stokes, Bluefield Process Safety and Grandperspective GmbH.
This month's front cover is brought to you by Kreber.
