The quarterly Electronic International Fertilizer Correspondent (e-ifc) provides a chanel for the latest research findings from IPI projects. It also includes details about K in the literature and up-coming IPI events.
Other developing issues and topics that may have an impact on nutrient management are discussed in the 'K for thought' section.
As well as reading the current and back issues online, you can also subscribe to our e-ifc email alert service. For more information on this free service, please visit the subscription page.
